learn.whatIsHeading
Power measures the rate of energy transfer or work done per unit time. The SI unit is the watt (W = J/s). Power converters convert between watts, kilowatts, horsepower, BTU/hr, and calories/second.
分步指南
- 11 watt = 1 joule/second
- 21 kilowatt (kW) = 1,000 W
- 31 mechanical horsepower (hp) = 745.7 W
- 41 metric horsepower (PS) = 735.5 W
- 51 BTU/hr = 0.2931 W
例题解析
输入
150 horsepower engine
结果
111,855 W ≈ 111.9 kW
150 × 745.7 = 111,855 W
输入
2 kW electric heater
结果
2.68 hp · 6,825 BTU/hr
2000 ÷ 745.7 = 2.68 hp
