 dyne  g cm/s^{2}  i dyne
 CGS unit of force. One dyne is the force that accelerates a mass of one gram at the rate of one centimeter per second per second. Expressed in SI units, the dyne equals 10^{5} newton.

 Poundal  i Poundal
 English unit of force used in engineering. One poundal is the force that accelerates a mass of one pound at the rate of one foot per second.

 N  i Newton
 SI unit of force. A force of one newton will accelerate a mass of one kilogram at the rate of one meter per second per second.

 lb_{f}  i pound force
 One pound of mass is 0.453 592 kilograms and the acceleration of gravity averages 9.806 65 m/s^{2} at the surface of the Earth, one pound force equals the product of these two numbers, 4.448 221 615 newtons.

 kg_{f}  i kilogram force
 Unit of force equal to the gravitational force on a mass of one kilogram.

 kN  i Kilo Newton

 Sthene  i Sthene
 Metric unit of force, part of the metretonnesecond system sometimes used by European engineers. One sthene is the force required to accelerate a mass of one tonne at a rate of 1 m/s^{2}. Thus the sthene is equal to the kilonewton

 kip  i kip
 Informal unit of force, sometimes used by engineers to express the amount of weight borne by a structure. One kip equals 1000 pounds (453.59 kilograms) of force or about 4.4482 kilonewtons The name of the unit is an abbreviation of kilopound.

 tn_{f} US  i ton force US
