Results in Kilocalories: 1 Ws = 0.000239 kcal

## How to Convert Watt-seconds to Kilocalories

To convert a watt-second measurement to a kilocalorie measurement, divide the energy by the conversion ratio. One kilocalorie is equal to 4,184 watt-seconds, so use this simple formula to convert:

kilocalories = watt-seconds ÷ 4,184

The energy in kilocalories is equal to the watt-seconds divided by 4,184.

For example, here's how to convert 5,000 watt-seconds to kilocalories using the formula above.
5,000 Ws = (5,000 ÷ 4,184) = 1.195029 kcal

## 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.

## Kilocalories

One kilocalorie, is equal to the heat needed to raise the temperature of one kilogram of water from 14.5 to 15.5 degrees Celsius.

Kilocalories can be abbreviated as kcal, for example 1 kilocalorie can be written as 1 kcal.

When being used to measure nutrition or metabolic processes, the large calorie is used, which is equal to one kilocalorie.
