The joule and the kilowatt-hour are both units of energy. 15 kw · h is equivalent to how many joules? answer in units of j.

The solution for the problem is:

1 Watt = 1 Joule per second

1 Watt*second = 1 Joule

a Kilowatt is 1,000 Watts

an hour is 60 seconds times 60 minutes or 3,600 seconds

a Kilowatt * hour is 1,000 Watts in 3,600 seconds

15 W*h = 15,000 Watt*hour = 15,000 Watt * 3,600 seconds = 54,000,000 Watt*second

54,000,000 Watt*second = ? Joules

54,000,000 Joules / second = 54,000,000 Watts
