1千瓦时等于多少度电
1千瓦·时(kW·h)=1度(kW·h)。
度,中国家庭电量常用单位,即千瓦时,符号为KW·h,功率为1000瓦的设备一小时的耗电量为1度电。
千瓦时就是平时所说的“度”,是电功的单位,符号:kW·h,计算公式为功率乘以时间。假设一台耗电设备的功率为2500瓦,即其一小时的耗电量为2.5千瓦时,也就是一小时2.5度电。
扩展资料:
电功率的公式:P=W/t (公式中的t表示时间,基本单位为秒-s,也常用单位小时-h来作计算)
电功率的测量公式:P=UI (公式中的U表示电压,基本单位为伏特-V;大写I表示电流,基本单位为安培-A)
根据欧姆定律:U=IR (公式中的R表示电阻,基本单位为欧姆-Ω)。
千瓦·时的单位转换:
一千瓦·时等于:3.599712×10焦耳。
一千瓦·时等于:1.3596112米制马力·时。
一千瓦·时等于:1.3408927英制马力·时。
一千瓦·时等于:8.599712023×10 千卡。
一千瓦·时等于:3.411×10 英热单位。

一千瓦时等于多少度
1千瓦时(千瓦时)=1度。千瓦(Kilowatt),早期为电的功率单位,现在有延伸为整个物理学领域功率单位的趋势。在容电学上,千瓦时(Kilowatt-hour)与度完全相等,只是称谓不同。
简介
“千瓦时”这个单位主要用于量度电力,因为“千瓦时”比焦耳更容易被大众了解,并更易转化为电器使用时数。另一方面,焦耳相对“千瓦时”的单位量度太小,较不方便计算,而中国大陆亦有公共机构在收费单上使用“兆瓦时”来代替“千瓦时”。在中文里,"千瓦"有时被写为瓩。
单位换算
1千瓦时的物理意义是:功率为1kW的电器,工作1小时所消耗的电能(或说工作1小时所做的功)一千瓦时相等于:3.599712×106焦耳,1.3596112米制马力时,1.3408927英制马力时,8.599712023×102千卡,3.411×103英热,2.655147×106英尺磅。
1千瓦时等于多少度?
1度=1千瓦·时
就是:1000瓦×1小时,也就是说如果有一台功率为一千瓦的热水器,它工作一小时所消耗的电能是一度。千瓦时就是平时所说的“度”,是电功的单位,符号:kW·h。
千瓦·时是一种能量量度单位,表示一件功率为一千瓦的电器在使用一小时之后所消耗的能量,或等于3.6百万焦耳。
“千瓦‧时”这个单位主要用于量度电力,因为“千瓦‧时”比焦耳更容易被大众了解,并更易转化为电器使用时数。再加上焦耳这个单位比较小,与千瓦·时相比单位量度太小,所以很少使用。
