How to Convert Watt-seconds to Watt-hours

To convert a watt-second measurement to a watt-hour measurement, divide the energy by the conversion ratio. One watt-hour is equal to 3,600 watt-seconds, so use this simple formula to convert:

watt-hours = watt-seconds ÷ 3,600

The energy in watt-hours is equal to the watt-seconds divided by 3,600.

For example, here's how to convert 5,000 watt-seconds to watt-hours using the formula above.
5,000 Ws = (5,000 ÷ 3,600) = 1.388889 Wh

Watt-seconds and watt-hours are both units used to measure energy. Keep reading to learn more about each unit of measure.

Watt-seconds

The watt-second is a measure of electrical energy equal to one watt of power over a one second period. One watt-second is equal to 1/3,600 of a watt-hour or one joule.

Watt-seconds can be abbreviated as Ws, for example 1 watt-second can be written as 1 Ws.

Watt-hours

The watt-hour is a measure of electrical energy equal to one watt of power over a one hour period.

Watt-hours can be abbreviated as Wh, for example 1 watt-hour can be written as 1 Wh.
