Technical measurement units
Power and force are different physical quantities, so different units are used for each. Here are some examples:
Units of Force
- Newton (N) - SI unit
- Dyne (dyn) - CGS unit
- Pound-force (lbf) - Imperial unit
- Kilogram-force (kgf)
Units of Power
- Watt (W) - SI unit
- Horsepower (hp) - British and American unit
- Foot-pounds per minute
- Foot-pounds per second
- BTU per hour (BTU/h)
- Calories per hour
- Erg per second (erg/s) - CGS unit
Units of Energy
- Joule (J) - SI unit
- Calorie (cal) - commonly used for heat energy
- British Thermal Unit (BTU)
- Electronvolt (eV) - used for energy at the atomic and molecular scale
- Foot-pound (ft·lb)
- Erg - CGS unit
