A watt is 1 Joule per Second (1 J/s). E.g. Every second, your device draws 1 Joule of energy. This energy over time is called "Power" and is a rate of energy transfer.

A watt-hour is (1 J/s) * (1 hr)

This can be rewritten as (3600 J/hr) * (1 hr). The "per hour" and "hour" cancel themselves out which makes 1 watt-hour equal to 3600 Joules.

1 kWh is 3,600 kJ or 3.6 MJ
