Convert watts, kilowatts and megawatts to mechanical horsepower, metric horsepower (PS) and BTU per hour — for appliances, motors, engines and solar panels.
A 2 kW kettle is 2.68 mechanical horsepower in engine terms, or 6,824 BTU per hour of heat.
Result = input × source-unit factor ÷ destination-unit factor. All factors are relative to the same base unit; intermediate values are not rounded.
Watts, Kilowatts, Megawatts, Horsepower (mechanical), Metric horsepower (PS), BTU/hour. Read the labels carefully: regional or decimal/binary variants are separate choices.
Mechanical horsepower (745.7 W) comes from James Watt's steam-engine comparisons; metric PS (735.5 W) is defined as 75 kilogram-metres per second. Car specs use one, the other, or kilowatts.
