Enter the power in watts (W), time period in hours (h), then press the **Calculate** button to get the result in watt-hours (Wh).

## Watts to Wh calculation

E_{(Wh)} = P_{(W)} × t_{(h)}

The energy **E** in watt-hours (Wh) is equal to the power **P** in watts (W), multiplied by the time period **t** in hours (h).
