Converting Watts to Amps The conversion of Watts to Amps at fixed voltage is governed by the equation Amps = Watts/Volts For example 12 watts/12 volts = 1 amp Converting Amps to Watts The conversion of Amps to Watts at fixed voltage is governed by the equation Watts = Amps x Volts For example 1 amp * 110 volts = 110 watts Converting Watts to Volts The conversion of Watts to Volts at fixed amperage is governed by the equation Volts = Watts/Amps For example 100 watts/10 amps = 10 volts Converting Volts to Watts The conversion of Volts to Watts at fixed amperage is governed by the equation Watts = Amps x Volts For example 1.5 amps * 12 volts = 18 watts Converting Volts to Amps at fixed wattage The conversion of Volts to Amps if the wattage is known is governed by the equations Amps = Watts/Volts For example 120 watts/110 volts = 1.09 amps Converting Amps to Volts at fixed wattage The conversion of Amps to Volts if the wattage is know is governed by the equation Volts = Watts/Amps For Example, 48 watts / 12 Amps = 4 Volts Converting Volts to Amps at a fixed resistance If you know the volts and the load of the resistance the amps are found by Ohm's law: Amps = Volts / Resistance Converting Amps to Volts at fixed resistance If you know the amps and the resistance Ohm's law becomes Volts = Amps * Resistance
