How do you calculate watts from volts?
To obtain Volts you need both Watts and Amps: The formula is (W)/(A) =(V). For example, if you have a power of 10W with a current of 2A the voltage is 10W / 2A = 5V. This comes from the equation V = P / I. Where P is the power in Watts, I is the current in Amps and V is the voltage in Volts.

How do I calculate wattage?
Steps
- The number of watts is equal to amps multiplied by volts. That’s it!
- For example, if the current is 3 amps (3A) and the voltage is 110V, you multiply 3 by 110, to get 330W (watts). The formula is P=3A X 110V = 330 W (with P standing for power).
- This is why watts are sometimes called volt-amps.
How many watts does a 12 volt battery have?
How many Watt-Hours in a battery?: Watts are pretty simple – it is just battery voltage times amp-hours. A 12 volt 105 AH battery can supply (under perfect conditions and to 100% discharge) 12 x 105, or 1260 Watt-hours (1.26 kWh).
