## How to Convert Watt-Seconds to Watt-Hours

To convert a measurement in watt-seconds to a measurement in watt-hours, divide the energy by the following conversion ratio: 3,600 watt-seconds/watt-hour.

Since one watt-hour is equal to 3,600 watt-seconds, you can use this simple formula to convert:

watt-hours = watt-seconds ÷ 3,600

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

**For example,**here's how to convert 5,000 watt-seconds to watt-hours using the formula above.

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

## What Is a Watt-Second?

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.

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]}

## What Is a Watt-Hour?

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.
