功率转换器 - 转换 W、kW、hp、BTU/h

如何将 horsepower 转换为 watts？ To convert mechanical horsepower (hp) to watts, multiply by 745.7. For example, 100 hp = 100 × 745.7 = 74,570 watts (74.57 kW). Note: metric horsepower (PS) = 735.5 watts, electric horsepower = 746 watts.

不同类型马力有何区别？ Mechanical horsepower (hp) = 745.7 W, metric horsepower (PS/CV) = 735.5 W, and electric horsepower = 746 W. Mechanical hp is used in the US, PS in Europe, and electric hp for motors. The differences are small but matter for precision.

一千瓦等于多少瓦？ One kilowatt (kW) equals exactly 1,000 watts (W). Similarly: 1 megawatt (MW) = 1,000,000 W, 1 gigawatt (GW) = 1,000,000,000 W. This is the standard SI metric system for power.

HVAC 系统中的每小时 BTU（BTU per hour）是什么？ BTU/h (British Thermal Unit per hour) measures heating/cooling power. 1 BTU/h = 0.293 watts. Air conditioners are often rated in BTU/h (e.g., "12,000 BTU" actually means 12,000 BTU/h ≈ 3.5 kW or 1 ton of refrigeration).

什么是制冷吨（ton of refrigeration）？ 制冷吨等于 12,000 BTU/h，约为 3.517 kW。它表示在 24 小时内将一吨（2,000 磅）水冻结所需的制冷能力，常用于空调系统的额定。
