SAE stands for Society of Automotive Engineers. This form of measurement was used primarily on cars made in the USA. This is why more often than not if you’re in the United States, you’re most likely finding wrenches and sockets in SAE sizings. AE sockets are sized in inches and fractions of inches.
What does SAE and MM stand for?
Tool measurements are either “Metric” or “Standard.” The latter refers to SAE tools. SAE tools are measured in 1/1000 of an inch. Metric tools are measured by the metric system. The “mm” listed on metric tools refers to millimeters.
What size is 18mm in SAE?

What is the difference between Imperial and SAE?
SAE is a reference to the American standard sizes for parts and tools. USCS is the American system of units in which SAE standard sizes are measured. Imperial is another system of units formerly used in the UK.
What is SAE used for?
SAE is commonly used in North America to indicate United States customary units (USCS or USC) measuring systems in automotive and construction tools. SAE is used as a tool marking to indicate that they are not metric (SI) based tools, as the two systems are incompatible.
Does SAE stand for?
The letters SAE stand for the Society of Automotive Engineering. The SAE was founded in 1905 by Andrew Ricker and Henry Ford. At the outset, its sole aim was to provide an umbrella organization for the scattered automotive engineers who usually worked alone in various parts of the country.
What is SAE vs metric?
Metric and SAE wrenches have different systems of measurement. Metric sockets and wrenches use the metric measurement system. … SAE wrenches use the imperial measurement system, mostly used in the United States, where it’s described using inches, or fractions of an inch. For this, you’d get a 1/3inch wrench or socket.

Is SAE the same as Whitworth?
These bolts have a fine thread, with a different thread count from an American National Fine (also known as SAE). The BSF threads have an included angle as the Whitworth threads, with an included angle of 55° where as the American National Fine (SAE) threads have an included angle of 60°.

What is SAE oil?
SAE stands for Society of Automotive Engineers. The SAE developed a numerical classification system to define the viscosity or thickness of oil. … Basically, the higher the number in a Monograde oil, the thicker the oil would be at operating temperature.
What is standard and metric?
Standard vs Metric Wrench The Measurements
They have varied methods of measuring the width, diameter, and length. The metric wrenches will give you the measurement in 10cm, 8mm, and so on. But a standard wrench, on the other hand, will be measured in inches and therefore might include some fractions.
What are SAE units?
Standard American English and the Metric System
Today, measuring in feet and inches is part of the Standard American English (SAE) or Imperial units of measurement, along with volumes like gallons and fluid ounces and weights like pounds. It’s standard in the United States and two other countries in the world.
