How to Convert Kilowatt-Hours to Watt-Seconds

To convert a measurement in kilowatt-hours to a measurement in watt-seconds, multiply the energy by the following conversion ratio: 3,600,000 watt-seconds/kilowatt-hour.

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

watt-seconds = kilowatt-hours × 3,600,000

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

For example, here's how to convert 5 kilowatt-hours to watt-seconds using the formula above.
watt-seconds = (5 kWh × 3,600,000) = 18,000,000 Ws

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.

What Is a Kilowatt-Hour?

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]

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.
