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.
