## How to Convert Watt-hours to Watt-seconds

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

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

**For example,**here's how to convert 5 watt-hours to watt-seconds using the formula above.

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

## Watt-hours

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

Watt-hours are usually abbreviated as *Wh*, although the formally adopted expression is *W·h*. The abbreviation *W h* is also sometimes used. For example, 1 watt-hour can be written as 1 Wh, 1 W·h, or 1 W h.

In formal expressions, the centered dot (·) or space is used to separate units used to indicate multiplication in an expression and to avoid conflicting prefixes being misinterpreted as a unit symbol.^{[1]}

## 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 are usually abbreviated as *Ws*, although the formally adopted expression is *W·s*. The abbreviation *W s* is also sometimes used. For example, 1 watt-second can be written as 1 Ws, 1 W·s, or 1 W s.
