FAQs

How many watts are in one horsepower?
One mechanical horsepower equals 745.69987 watts, which is about 0.7457 kilowatts. This tool uses that standard mechanical definition for all horsepower conversions.
What is the difference between mechanical and metric horsepower?
Mechanical horsepower (about 745.7 watts) is based on 550 foot pounds force per second and is common in the US and UK. Metric horsepower (about 735.5 watts) is slightly smaller. This converter uses mechanical horsepower.
How do I convert kilowatts to horsepower?
Divide the kilowatt value by 0.74569987, or multiply by about 1.34102. For example, 5 kW is roughly 6.7 horsepower. Just select kilowatt as the from unit and horsepower as the to unit here.
Is one megawatt the same as a thousand kilowatts?
Yes. One megawatt equals 1000 kilowatts, which is one million watts. Megawatts are typically used to describe large power plants and grid scale generation.
Does this tool round the results?
Results are shown to six significant figures and trailing zeros are trimmed for readability. The underlying calculation keeps full precision, so copied values reflect the rounded display.
