How to Convert Kilocalories to Watt-seconds

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

watt-seconds = kilocalories × 4,184

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

For example, here's how to convert 5 kilocalories to watt-seconds using the formula above.
5 kcal = (5 × 4,184) = 20,920 Ws

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

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.

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.
