How to Convert Watt-seconds to Watt-hours

Convert watt-seconds to watt-hours with this simple formula:

watt-hours = watt-seconds × 0.000278

Converting a watt-second energy measurement to a watt-hour measurement involves multiplying the energy by the conversion ratio to find the result. One watt-second is equal to 0.000278 watt-hours, so to convert simply multiply by 0.000278.

For example, here's how to convert 5 watt-seconds to watt-hours using the formula above.
5 Ws = (5 × 0.000278) = 0.001389 Wh
