How to convert watts to amps and amps to watts at a fixed voltage The formula for converting Watts to Amps is : Watts = Amps * Volts The formula for converting Amps to Watts is : Amps = Watts / Volts SAFTEY WARNING : Only use 80% of the circuit breaker capacity! Common Conversions at 110 volt! Watts to Amps : 1000W / 110V = 9.1A 600W / 110V = 5.4A 400W / 110V = 3.6A 250W / 110V = 2.3A Amps to Watts : 10A * 110V = 1100W and 80% safe usage is 880W 15A * 110V = 1650W and 80% safe usage is 1320W 25A * 110V = 2750W and 80% safe usage is 2200W 30A * 110V = 3300W and 80% safe usage is 2640W Common Conversions at 240 volt! Watts to Amps : 1000W / 240V = 4.1A 600W / 240V = 2.5A 400W / 240V = 1.7A 250W / 240V = 1.1A Amps to Watts : 10A * 240V = 2400W and 80% safe usage is 1920W 15A * 240V = 3600W and 80% safe usage is 2880W 25A * 240V = 6000W and 80% safe usage is 4800W 30A * 240V = 7200W and 80% safe usage is 5760W __________________ Please feel free to contact us with any questions at rdc@rdc-electrical.com.
