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

To convert a kilowatt-hour measurement to a watt-second measurement, multiply the energy by the conversion ratio.

Since one kilowatt-hour is equal to 3,600,000 watt-seconds, you can use this simple formula to convert:

The energy in watt-seconds is equal to the kilowatt-hours multiplied by 3,600,000.

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

### How Many Watt-seconds are in a Kilowatt-hour?

There are **3,600,000** watt-seconds in a kilowatt-hour, which is why we use this value in the formula above.

1 kWh = 3,600,000 Ws

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

## 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 are usually abbreviated as *kWh*, although the formally adopted expression is *kW·h*. The abbreviation *kW h* is also sometimes used. For example, 1 kilowatt-hour can be written as 1 kWh, 1 kW·h, or 1 kW 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.
