Question

express 1KWH in joules

Answer 1

Hiii machiii ✋..

➡️ 1 kWh = 1,000 J/s × 3,600 s. 1 kWh = 3,600,000 J. 1 kWh = 3·6 MJ

(mega joules: see prefixes) The kWh is a large unit of energy used to measure.

Answer 2

One kilowatt-hour is equal to 3600000 joules:

1kWh = 3600000J = 3.6⋅106J = 3.6MJ

So the energy in joules E(J) is equal to 3600000 times the energy in kilowatt-hour E(kWh):

E(J) = 3600000 ⋅ E(kWh)
