Supported Units

Watts (W) - SI unit of power; commonly used in electrical devices and energy systems.
Kilowatts (kW) - 1,000 watts; used for household appliances, solar panels, and small generators.
Megawatts (MW) - 1,000,000 watts; used in power plants and industrial-scale systems.
Horsepower (hp) - Used to rate engines and motors; multiple definitions (mechanical, metric, electrical).

Common Uses

Comparing car engine power ratings (e.g., hp to kW)
Converting solar panel output or generator ratings
Evaluating appliance power consumption
Calculating HVAC system requirements

Interpreting energy production in industrial or utility-scale settings

Frequently Asked Questions

How many watts are in one horsepower?

One mechanical horsepower is approximately 745.7 watts

What's the difference between kW and kWh?

kW (kilowatt) is a measure of power (rate of energy use), while kWh (kilowatt-hour) is a measure of energy consumed over time.

Why do some devices use horsepower instead of watts?

Horsepower is traditionally used for engines and motors because it was historically developed to quantify work done by machines like steam engines and cars, especially in the imperial system.

Can I use kilowatts and horsepower interchangeably?

They measure the same physical quantity (power), but their numerical values differ. 1 kW = 1.341 hp (mechanical), so a conversion is needed.
