Kilocalories to Watt-seconds Conversion
Enter the energy in kilocalories below to get the value converted to watt-seconds.
How to Convert Kilocalories to Watt-seconds
To convert a kilocalorie measurement to a watt-second measurement, multiply the energy by the conversion ratio.
Since one kilocalorie is equal to 4,184 watt-seconds, you can use this simple formula to convert:
The energy in watt-seconds is equal to the kilocalories multiplied by 4,184.
How Many Watt-seconds Are in a Kilocalorie?
There are 4,184 watt-seconds in a kilocalorie, which is why we use this value in the formula above.
1 kcal = 4,184 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 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.
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]
