- What is the practical difference between kW and kWh on an electricity bill?
- kW is power (how fast energy is used), while kWh is energy (how much was used over time). Your electricity bill charges for kWh: a 2 kW heater running for 3 hours uses 6 kWh.

- Historically different industries adopted different conventions. Automotive and industrial contexts in the US use horsepower, while the SI system uses kilowatts. Modern standards increasingly prefer kW, but horsepower persists in marketing.
