功率 Converter
免费功率转换器, 即时换算瓦特、千瓦、马力和英热单位/小时
使用 OmniConverter 免费在线功率换算器在瓦特、千瓦和马力之间即时换算。1 千瓦等于 1,000 瓦，1 马力等于 745.7 瓦。无论你是比较发动机功率、计算电力消耗还是解决工程问题，都能获得精确的实时换算。
使用方法
通过三个简单步骤进行转换。
输入功率值
在「输入值」字段中键入您的功率测量值。例如，输入 100 转换 100 瓦，或输入 1.5 转换 1.5 千瓦。
选择源功率单位与目标单位
在左侧选择输入单位（例如瓦、千瓦、兆瓦、马力、BTU/小时），在右侧下拉菜单中选择所需输出单位。
查看转换后的功率输出
结果会实时计算并显示。非常适合比较发动机功率、电器能耗、太阳能板以及工业或机械功率需求。

实际应用场景
在中国，汽车功率通常用马力（PS）表示，但官方登记证书上标注的是千瓦（kW）。1马力=0.735千瓦，一台大众速腾150马力相当于110千瓦。电动车时代，消费者比较特斯拉Model 3（194kW/264马力）和比亚迪汉（180kW/245马力）时需在两种单位间切换。空调的制冷量用「匹」表示, 1匹≈2.5kW, 这与国际通行的BTU/hr（1匹≈8,000 BTU/hr）并存。购买空调时要换算清楚。家庭用电功率：电磁炉2,200W、电热水器3,000W，但计算同时使用率时要考虑总功率不能超过电表容量（居民通常8-12kW）。太阳能光伏板按峰瓦（Wp）计算，一个典型家庭户用系统约5-10kWp。在物理课上，学生需掌握W与kW·h的区别。工业电机铭牌上同时标有kW和HP。中国电网频率统一50Hz。

常见换算问题的快速解答
空调匹数与功率如何换算？+
一匹约等于735瓦（0.735 kW）。1.5匹空调约1,100 W。
电动车充电功率怎么算？+
家用慢充约7 kW（220V 32A）。快充桩可达120 kW以上。
如何将kW换算成马力？+
kW乘以1.341即可得到马力（HP）。
如何将W换算成kW？+
W除以1,000即可得到kW。
一台家用电器功率怎么看？+
电热水壶约1,500 W（1.5 kW），电饭煲约700 W，空调约1,000-2,000 W。
如何将BTU/h换算成kW？+
BTU/h乘以0.000293即可得到kW，用于空调制冷量。1匹≈2,500 BTU/h。
1度电等于多少千瓦时？+
1度电 = 1 kWh。1000瓦电器使用1小时消耗1度电。
