With the metric conversion table above, standard to metric conversion should hopefully be a breeze!

With the dynamic society we live in, we are required to have basic knowledge of the units of measurements used today, which are either SAE and metric. We, however, are primarily conversant with only the system used in our home countries.

Conversion from SAE to the metric system is a tiring and grueling experience. Conversion charts are tables designed to help you easily switch from one to another without making any errors. Many people often complain that the charts in circulation are challenging to use; we decided to create and design one that you can quickly utilize.

Do I need a table? This is a question that we often ask. What we fail to realize is that different items come in various measuring systems. The king-sized bed you use could be sold in inches while bedding is in centimeters; thus, having basic knowledge of the sizes will help you choose the right sized items. Placing your orders in online businesses requires prior knowledge of the goods needed to avoid costs incurred on returning.

Choosing the appropriate wrench size for basic repairs will test your knowledge of the units as well. Their sizes could be written in millimeters while those of nuts and bolts are in inches. Our table will quickly help you navigate through such experiences.

Have you ever traveled to a foreign country and found measuring volume units different from what you are used to? Maybe water sold in ounces or petrol in gallons? To refill enough gas for your car, conversion to volume units you are familiar with is vital. Evening news bulletin giving the price of crude oil in barrels while we only understand liters necessitates a relevant chart.

It is advisable to have your work done to perfection. A task as easy as buying an electric cord for your house could leave you homeless! The reason for this being if you get the wrong one, it could lead to a fire that will burn down your house. Nonetheless, you can view an electrical cord guide here.

For your convenience, we have listed the SAE equivalents in Millimetres, centimeters, inches and even feet! Let’s take a closer look at all of these in detail.

What is SAE, Or Standard?

SAE stands for Society of Automotive Engineers, now known as SAE International, who standardized the units for ease of usage. The organization has a membership of over 138,000 all over the world and is responsible for advancing and setting standards in the engineering space. SAE has set standards for measurement that are not only followed by most of North America’s construction and automotive industry, but have also made engineering, production and the sales aspect a piece of cake.

Units of measurement are a medium of communication; hence standard size lengths were needed to enhance accuracy. The system was initially developed by the Roman Empire, where one foot was generally the length of a foot of a human being. An inch, however, was the width of a thumb.

SAE International took these basic units one step further and developed the evolved SAE system of measurement and continues to spread other technical information and set North American standards in the construction and auto industry through its forums, magazines, journals and periodicals.

It is mainly used in the UD and formerly in the UK. In the UK, it is referred to as the Imperial system. Other countries adopted another method of measurement, metric, leaving the two countries as the system’s primary users. Units of division in this system are in eighths and twelfths. With these scale graduations, it becomes tough to read the scale.

SAE units are also granted the label of UD Customary Units (USCS). This indicates that it is the official unit use in USA and is not the same as the Metric system and is also incompatible with the British Imperial system. It is a common mistake to use the Imperial system and SAE interchangeably, but the both are different systems of measurement.

They were used during the industrial revolution in the USA, thus cementing their use. The manufacturing and construction industry adapted its use as the accepted standard. You can use our metric to standard conversion tables to get the units you may need for your project. Now let us take a closer look at the metric system used in other parts of Europe and some parts of Asia and Africa too.

What is the Metric System?

It is a measurement system that was developed in the 18th century after the French Revolution. It is a measurement system with meter, liter, and gram as the standard for length, volume, and mass. You will most certainly realize this model of representing lengths is the most common globally.

Units of measurements are subdivided into tenths, making the reading of this scale much easier than the other systems. The most common engineering level of the scale is the millimeter (mm). It is easier to read, and, being the smallest, it can represent any length.

What makes the system most resourceful is the ability to be intuitive and interconnected, for instance 1 liter of water will weigh 1 kg.

Thanks to it’s convenient method of measurement and Napoleons triumphs all over Europe, this system of standardization spread far and wide. Great Britain also accepted some parts of the metric units over the British Imperial system. The older generations in Britain may still use the older Imperial method but the youngsters prefer their kilograms and millimeters.

What are millimeters and centimeters used for?

Both Millimeters(mm) and centimeters(cm) are part of the metric system. While MM is a unit of length, CM can be used for both length and area. One MM is 0.1cm and one CM is 10mm. Since MM is the smaller unit, it is used in the denotation of the very small but visible lengths and distances. For instance the thickness of a wire, the length of your nail, and size of an insect sized specimen in a lab.

A centimeter on the other hand, is a larger unit and is roughly the 100th part of a meter. It can be used to measure the size of medium range objects, for instance, the distance between two points in the vicinity. Where larger distances are involved, the meter is chosen over the centimeter.

SAE (Standard) vs. METRIC UNITS

When it comes to the whole debate of SAE (standard) vs metric, here’s what you need to know.

SAE was, with time, incorporated into the whole automotive industry. In the beginning, the standard was only used for vehicles. However, they are currently utilized in all modes of transport. Airplanes and boats adapted the system to become the preferred means of measurement when SAE changed from Society of Automobile Engineers to Society of Automotive Engineers.

The metric system is more prevalent in other countries. Major vehicle manufacturing hubs such as Japan, Germany, Korea and France use this mode. As a result, we now have vehicles with nuts and bolts in the metric system, which led to the development of SAE wrench sizes and metric-sized wrenches.

Needless to say, this also means that if you’re an engineer looking to work on a foreign car from the metric parts of the world like a Nissan, Kia or Subaru, you’re going to be buying metric equipment like sockets. But if you’re only looking at the domestic market, then you’re good to go with SAE sockets.

Nowadays, however another innovation is also becoming more and more popular. Due to rising production costs in the USA, their big vehicle manufacturing companies source some parts in other countries. The trend has led to vehicles having different components with different measuring systems. You could find the engine and its members in the metric system while the rest of the car is in SAE, giving rise to the need for universal wrenches.

Repairs now require high-precision tools such as plasma glass cutters which accurately cut whatever component you need, or MIG welders for simple welding jobs. With vehicles now considered expensive investments, choosing the perfect wires for repairs requires an expert opinion.

Metric vs. Imperial System

For imperial vs metric, take a look at this section to get a better understanding of the two.

The Imperial system is a form of older standardizations that has now given way to more logical and thoughtful designs. It was mainly used in the UK. One foot was subdivided into twelve units or inches, whereas formerly, it was equal to 11.6 inches. We can now quickly and comfortably represent inches as a foot or vice versa. All these changes were made in ancient times by the monarch hence the name Imperial.

The UK, however, transitioned over later on. It was necessitated by the need to have a standard unit globally. The French had developed the metric system after the French Revolution and Napoleon’s conquets led to it’s acceptance in other lands.

Currently, it is the base International System of Units (SI) for length; if you use or understand both the metric and imperial system, you will find the former easier to use.

SI Units

These are universal units of measurements that were agreed on to reduce confusion that came with data representation. With these, scientists can easily discuss their findings globally. An engineer can design a car in Germany and send the design to China, where it will be manufactured to the exact length.

Preparing various tools of different sizes for motor vehicles needs high-quality lathe machines. We have prepared a list of high precision and easy to use lathe machines. They will give you the best quality for your money with medium-sized lathes which can fit in your garage.

What is the inch used for?

The inch is also a unit used commonly in both the USCS and the imperial units. Throughout history, it’s denotation has been shifting and adapting to the modern times. Originally meaning one-twelfth of a Roman foot, during the reign of King David I of Scotland, an inch went on to mean the size equal to the breadth of a mans thumb. But under the monarchy of King Edward II in the 14th century, the inch represented the size equal to three grains of dry barley, placed lengthwise next to each other.

Don’t worry though, today you won’t need barley to do the math. An inch officially means 2.54cm as of 1959.

What is the foot used for?

The origin of this one shouldn’t be too hard to guess. Human body parts were popular tools for measurement all around the world. While the foot was popular in Greece, Rome and China, other places used the cubit for units of length and area. While the standard Roman foot was 295.7mm, the Greek foot was around 302mm. This measurements changed again after the fall of these empires.

In England, archeologists have identified the use of this widespread unit dating back to the contruction of the Stone henge in the form of the Neolithic foot.

Due to the controversial nature of its denotation, it was not surprising that an international conference had to meet and standardize its value.

In imperial units, a standard foot denotes the value of 1/3 yard. But since 1959’s International Yard and pound agreement, the yard was standardized to the 0.9144 meters. This clearly meant the international standard for the foot was then simultaneously set at 0.3048 meters. It is widely used for measuring lengths and distances between points till date.

Acres?

Have you tried to buy land sold in acres and didn’t know the extent of the size? Real estate, just like engine-driven welding machines, is a long-term investment that requires you to have full prior knowledge due to the enormous amounts of money involved.

Purchasing the land without having a mental image could lead you to buy land smaller or larger than you need. Letting of apartments and office spaces has now been converted to square units. Getting a good value for your money will only happen when you know how big it is. We will help you change to the units that you entirely relate to.

Acres are a measurement of land and is part of both the USCS and the Imperial systems. It was designed in the Middles ages as the area that could ideally be ploughed by one ox and one man in a single day.

Today, it stands for various measurements in different countries. In the USCS, one acre is roughly 4840 square yard, but in SI, it is 4046.9 square meters. In the Imperial system, an acre refers to 1/640 parts of a square mile.

Fun fact and note of caution, sometimes the Puerto Rican Cuerda is called the ‘Spanish Acre’ which is actually equivalent to 0.96 acres. Confusing acre and spanish acre could land you in some trouble, so make sure to keep the two separate!

Conversion at home

When moving to a new office or apartment, you need extension cords to power your appliances. Choosing the right power cables can be a real struggle. You can get advice on how to choose the right extension here. In the link, you will get tips on connection and usage from the experts.

It is a landowner’s dream to have well-manicured lawns and property landscaped to their liking. If you have a garden, it will require a tractor suited for your property size. A tractor is an expensive investment; hence its needs proper guidance before purchase. You should not only strive to buy a top-rated machine but also the best fit for performing tasks when required.

While revamping your home, you will need a basic understanding of the units of measurement. Some of the materials you will need, like wood, are sold in foot, whereas others are in meters. With this knowledge, you will easily prepare for the renovations needed in terms of how big or small your furniture should be. Even if you’re looking to purchase property or buying some car parts, knowing your British units from your the American ones will give you the upper hand even before you start browsing.
