Mistakes to avoid with power conversions
- kW vs kWh again: power is the rate, energy is the amount — a 2 kW kettle for 6 minutes uses 0.2 kWh.
- Mixing metric and mechanical horsepower (~1.4% apart) when comparing engine specs across regions.
- Sizing inverters/generators on running watts while ignoring appliance startup surges.
