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

To convert a watt-second measurement to a kilowatt-hour measurement, multiply the energy by the conversion ratio. One watt-second is equal to 2.7778E-7 kilowatt-hours, so use this simple formula to convert:

The energy in kilowatt-hours is equal to the watt-seconds multiplied by 2.7778E-7.

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

Watt-seconds and kilowatt-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.

## Kilowatt-hours

A kilowatt-hour is a measure of electrical energy equal to one kilowatt, or 1,000 watts, of power over a one hour period. Kilowatt-hours are a measure of electrical work performed over a period of time, and are often used as a way of measuring energy usage by electric companies.

Kilowatt-hours can be abbreviated as *kWh*, for example 1 kilowatt-hour can be written as 1 kWh.
