Apa itu?
Power is the rate of energy transfer per unit of time. In mechanics, it measures an engine's ability to perform work. Power is the key parameter for comparing vehicle engines, sizing electrical installations, and evaluating heating and cooling system performance. It is closely related to torque and rotational speed.

Aplikasi praktikal
The automotive industry uses HP and CV to describe engine power. Electricians work in kW for installation sizing. HVAC engineers use BTU/h for heating and cooling systems. The kW ↔ CV conversion is essential for vehicle registration documents in Europe.
Panduan unit
Watt (W)
SI unit of power. One Watt equals one Joule per second. Used universally in electricity and physics.
Kilowatt (kW)
One thousand Watts. Standard for electric motors, domestic installations, and electric vehicles.
HP (Horsepower)
Mechanical (imperial) horsepower. Defined by James Watt. 1 HP = 745.7 W. Standard in USA and UK.
CV (Cheval-vapeur)
Metric horsepower. 1 CV = 735.499 W. Used in Europe for vehicle engine power ratings.
BTU/h
British Thermal Unit per hour. Used in North America for heating, ventilation, and air conditioning (HVAC) systems.
Tips praktikal
- 1
Fiscal horsepower on registration documents is not the same as actual CV power.
- 2
A typical compact car engine develops 60-120 kW (80-160 CV).
- 3
Average household electrical power is 6-9 kW.
- 4
HP and CV are very close but not identical: 1 HP = 1.0139 CV.
