SAE International, initially established as the Society of Automotive Engineers, is a U.S.-based, globally active professional association and standards developing organization for engineering professionals in various industries. Principal emphasis is placed on transport industries such as automotive, aerospace, and commercial vehicles.
SAE International has over 138,000 global members. Membership is granted to individuals, rather than companies. Aside from its standardization efforts, SAE International also devotes resources to projects and programs in STEM education, professional certification, and collegiate design competitions.
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. A common mistake is to use SAE interchangeably with the word "Imperial" units (British), which is not the same as the USCS standard that SAE uses.
SAE is perhaps best known in the United States for its ratings of automobile horsepower. Until 1971-1972 SAE gross power was used. Similar to brake horsepower (bhp), it gave generously unrealistic performance ratings. Since then the more conservative SAE net power, which takes into account engine accessory, emissions, and exhaust drags (but not transmission losses) is the standard.
