Часто задаваемые вопросы
›How many watts in a horsepower?
1 mechanical horsepower (US/UK) = 745.7 W. 1 metric horsepower (PS, used in Europe) = 735.5 W. They differ by about 1.4%.
›kW or hp on car specs?
Both are used. 1 kW ≈ 1.341 mechanical hp. European car ads often list both, e.g. '150 kW (204 hp)'.
›What does BTU/h measure?
Heat output or cooling capacity over time — common on air conditioner and furnace ratings. 1 ton of cooling = 12,000 BTU/h ≈ 3,517 W.
›Is the converter free?
Yes — free, no signup, runs in your browser.
›How accurate is it?
Double-precision (15+ significant digits) — more than precise enough for engineering work.
