Watts to Amps Converter — Frequently Asked Questions
Q1 How many amps is 1500 watts at 120 volts? ▾
At 120V with a power factor of 1.0 (such as a standard electric space heater), 1,500 Watts draws exactly 12.5 Amps (1500 / 120 = 12.5 A).
Q2 How many amps is 2400 watts at 240 volts? ▾
At 240V, 2,400 Watts draws 10.0 Amps (2400 / 240 = 10 A).
Q3 What is power factor in AC electrical calculations? ▾
Power factor (PF) is the ratio of real working power (kW) to apparent power (kVA) in an AC circuit. Resistive heaters have a PF of 1.0, while electric motors and compressors typically have a PF of 0.8 to 0.9.
