Mechanical Units of Measure - Metric & English

Here is a collection of some of the most often used mechanical units. Both SI (metric) and SAE (English) units are given. There are two fundamental types of units: base units and derived units. Base units include meter, foot, kilogram, second, etc. Derived units involve a combination of base units, such as square meter, kilometer/second, etc.

 

Name SI Base Unit Symbol English Base Unit Symbol
Length meter m foot ft
Area square meter m2 square foot ft2
Volume cubic meter m3 cubic foot ft3
Mass kilogram kg pound mass lb
Density kilogram/cubic meter kg/m3 pound/cubic foot lb/ft3
Time second s second s
Speed kilometer/second km/s foot/second ft/s
Force newton N pound-force lbf
Pressure pascal P pound/square foot lb/ft2
Plane Angle radian rad degree °
Solid Angle steradian ster square degree deg2
Momentum kilogram*meter/second ρ pound*foot/second ρ
Torque newton*meter t pound-force*foot t
Young's modulus pascal E pascal E
Kinetic energy joule K watt*second K
Potential energy joule U watt*second U
