用电器的功率乘上使用时间(累计时间)就等于用电量。公式;KW*H=电量。用电量乘上当地的电价就是费用(元)。

一般家庭交电费的时候是按自己家这个月使用了多少度电,一度电按0.5元左右算的,比如这个月用电100度,电表上会显示的,那么这个月电费就是100度x0.5元=50元。那么这100度电是怎么得出来的呢?家用电器一般都标有功率,这个功率的意思就是这个电器开启一个小时能耗几度电,1000瓦=1度电,也就是标注功率为1000瓦的电器开启一个小时就耗1度电。那么一般的电器功率是多大呢?比如洗衣机功率大约为100瓦左右,那么一个小时就能耗0.1度电,热水器一般为1200瓦左右,那么开启一个小时就能耗1.2度电,还有一点要注意,电器上标注的功率是连续开启一个小时耗的电量,如果开半小时那就只耗标称功率一半的电量。
