About Kilowatt and Horsepower (mechanical)

Detailed information about both units of measurement.

METRIC UNIT

Kilowatt

kW
Definition
One thousand watts. Standard unit for appliance power, EV motors, and engine output worldwide.
SI / Standard Information
SI-derived unit (kW). 1 kW = 1,000 W. The most practical unit for household appliances and vehicle power ratings.
Approximate Comparison
A kilowatt is about the power of a microwave oven or a small space heater.
Practical Applications
  • Electric motor and EV power rating
  • Home appliance power specification
  • Generator and UPS capacity
  • Solar panel system output
Real-World Examples
  • A typical home's electrical service is 10-20 kW
  • An electric car motor is about 150-300 kW
  • A window air conditioner uses about 1-2 kW
IMPERIAL UNIT

Horsepower (mechanical)

hp
Definition
An imperial unit of power equal to 550 foot-pounds per second. Used for engine output in the US and UK.
SI / Standard Information
Defined as 745.7 W exactly. Originally defined by James Watt to compare steam engine output to draft horses.
Approximate Comparison
One horsepower is roughly the sustained power output of a draft horse or about 10-12 humans.
Practical Applications
  • US and UK vehicle engine power ratings
  • Lawn mower and small engine specs
  • Industrial motor power in the US
  • Marine engine specifications
Real-World Examples
  • A typical family car has 150-250 hp
