>It makes a lot of sense to specify energy in Wh in electrical engineering. It's much easier to convert to other useful measurements involving volts, amps, and watts than joules are. Easier how? A watt-hour is just 3600 joules - the number of seconds in an hour. 1 joule = 1 volt * 1 amp * 1 second 1 watt-hour = 1 volt * 1 amp * 3600 seconds
