1 Kilowatt = 1000 Watt

Key Formulas

Kilowatt → Horsepower (mech)

hp = kW × 1.34102

Horsepower (mech) → Kilowatt

kW = hp × 0.7457

Watt → Kilowatt

kW = W × 0.001

Kilowatt → Watt

W = kW × 1000

Formula

W = kW × 1000

Generator 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
