一千瓦时大概是用了几度电?
1千瓦时俗称一度电,是电能的单位。千瓦是功率单位,一千瓦时代表一千瓦功率的电器工作一小时所用的电能。
“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。
1kW·h = 3,600,000焦耳= 3.6 百万焦耳。
另外有比千瓦·时次一级的单位,为瓦·时(符号:W·h,在商品描述里为Whr) ,是“千瓦·时”的千分之一,一般有六枚电芯的笔电电池所储存的能量约为56 Whr。1W·h = 3,600 焦耳。
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。

1kw是多少度电?
1度电。
1千瓦时等于1度电。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。
1千瓦时等于1度电,千瓦时的缩写为度,也就是一种电工单位。2.1 kwh它代表的一个小时内功率为1000瓦的设备所消耗能量,所以影响家庭用电的因素也非常多,比如使用节能电器商品也会节省更多的一些电能等。
用电注意:
1、当我们在用电时,一定要有一些必备的工具,比方说验电笔,螺丝刀等这些工具都要有的,以免家里的线路出现问题,才能及时等到维修。
2、在家里,电表应安装在总保险上,因总保险安装到电表上它直接就会预防电表出现漏电这些事故。
3、在使用电源时,保险丝很容易熔断或是开关漏电事故,当我们需要在打开开关电源之前一定要找出原因。任何情况下都不能用电线压安全开关,强行送电容易造成触电事故。
4、当家居饰品与设备不满足家庭用电容量时,一定要及时更换,不能正常使用千万不能用,一旦过载操作就会损坏电气设备并且可能引起火灾。
一千瓦等于多少度电???
1千瓦时=1度电,千瓦时(kWh)是电能表抄表时的单位;千瓦时是一个能量量度单位,表示功率为一千瓦的电器使用一个小时的耗电量。
