1 Kilowatt = 1000 Watt
Key Formulas
Kilowatt → Horsepower (mech)
hp = kW × 1.34102Horsepower (mech) → Kilowatt
kW = hp × 0.7457Watt → Kilowatt
kW = W × 0.001Kilowatt → Watt
W = kW × 1000Formula
W = kW × 1000Generator and solar system specs are typically expressed in kilowatts, while individual appliance ratings appear in watts. When planning a backup power system, you need to convert the generator's 7 kW rating to 7,000 W to compare it directly against the watt draw of each appliance. The same applies when calculating a circuit's capacity: a 20-amp, 120 V circuit provides 2,400 W = 2.4 kW.

Real-World Examples
A 1 kW microwave oven draws 1,000 W — the standard benchmark for kitchen appliance power consumption.
1 kW = 1000 W
A 3.5 kW electric clothes dryer draws 3,500 W — one of the highest single-appliance loads in a home, significant for circuit sizing.
3.5 kW = 3500 W
A 7.2 kW Level 2 EV charger draws 7,200 W from a 240 V outlet — enough to add 25–30 miles of range per hour to most EVs.
7.2 kW = 7200 W
A 0.35 kW solar panel at peak sun produces 350 W — a standard residential panel size for rooftop arrays.
0.35 kW = 350 W
