Say you have an electric engine that consumes 8 amps at 12 V, and you would like to know how much this would translate in kilowatt hours?
Go to Google’s search box and type
8 amps * 12 v * 1 hour
And you will get the total output in Joules, which is 345,600 joules.
Then tell google
345600 joules to kwh
And google will tell you
0.096 kilowatt hours (which is what a small electric fan will consume in an hour), or the same as 8 * 12 = 96 watts * 1 hr, 96 Wh
Was trying to figure out how to do this again! I think I learned a little bit more by reading this though.
Also, for a one-liner version in kwh, do “(8 amps * 12 volts * 1 hour) in kwh”
