eli5 What is the difference between kW and kWh
In: 0
The main difference between kWh and kW is in what they measure. To put it simply, a kilowatt is a measure of power and a kilowatt-hour is a measure of energy; power is the rate at which something uses energy, and energy is the capacity to do work.
To put it simply, kW is how much juice something needs to work, and kWh is how much juice something has that can be used to make that thing work.
You’d use kW to measure something like a light bulb, and you’d use kWh to measure something like a battery.
