How many joules are in a kilowatt-hour?

There are 3,600,000 joules in 1 kilowatt-hour (kWh).

Detailed answer

Power × time: 1 kW = 1,000 J/s. Over 3,600 seconds (one hour), energy = 1,000 × 3,600 = 3,600,000 J = 1 kWh.

Relationship context

Electricity meters and utility bills use kWh; physics and SI work often convert to joules.
