Results in Watt-Seconds: 1 Wh = 3,600 Ws

Do you want to convert watt-seconds to watt-hours?

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

To convert a measurement in watt-hours to a measurement in watt-seconds, multiply 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-seconds = watt-hours × 3,600

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

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

### How Many Watt-Seconds Are in a Watt-Hour?

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

1 Wh = 3,600 Ws

## 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.

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.

## 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.
