The correct unit for measuring energy capacity of a battery product is called watt-hours. Watt-hours signifies that a battery can supply an amount of watts for an hour. For example, a 60 watt-hour battery can power a 60 watt light bulb for an hour. The same battery would run a 5W phone for 12 hours and power a 1W LED light bulb for 60 hours.
Appliance Watts/Amps Calculator. Electricity is measured in units of energy called watts, named after James Watt, the inventor of the steam engine. Watts is generally defined as the amount of power (or energy) an appliance uses (consumes) when operated at its maximum capacity for 1 hour . Amps on the other hand is defined as how much energy an appliance draws, or the rate of energy that flows through wire when an appliance is used for 1 hour. Finally, volts is what energizes the appliance or it is the force that pushes electricity through wire to the appliance.
