Calories to Watt-seconds Conversion
Enter the energy in calories below to get the value converted to watt-seconds.
How to Convert Calories to Watt-seconds
To convert a calorie measurement to a watt-second measurement, multiply the energy by the conversion ratio.
Since one calorie is equal to 4.184 watt-seconds, you can use this simple formula to convert:
The energy in watt-seconds is equal to the calories multiplied by 4.184.
Calories and watt-seconds are both units used to measure energy. Keep reading to learn more about each unit of measure.
Calories
One calorie is equal to the heat needed to raise the temperature of one gram of water from 14.5 to 15.5 degrees Celsius.
When measuring the energy content in foods, the large calorie, or kilocalorie is used, but it's often still just called a "calorie." When both the calorie and large calorie are used in the same context it is common to refer to the calorie as a "small calorie."
Calories can be abbreviated as cal; for example, 1 calorie can be written as 1 cal.
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]
