How to convert calories to watt seconds (cal to Ws)
The formula for converting calories to watt seconds is: Ws = cal × 4.1868. To calculate the calorie value in watt seconds first substitute the calorie value into the preceding formula, and then perform the calculation. If we wanted to calculate 1 calorie in watt seconds we follow these steps:
Ws = cal × 4.1868
Ws = 1 × 4.1868
Ws = 4.1868
In other words, 1 calorie is equal to 4.1868 watt seconds.
Let's take a look at an example. The step-by-step process to convert 9 calories to watt seconds is:
- Understand the conversion formula: Ws = cal × 4.1868
- Substitute the required value. In this case we substitute 9 for cal so the formula becomes: Ws = 9 × 4.1868
- Calculate the result using the provided values. In our example the result is: 9 × 4.1868 = 37.6812 Ws
In summary, 9 calories is equal to 37.6812 watt seconds.
Converting watt seconds to calories
In order to convert the other way around i.e. watt seconds to calories, you would use the following formula: cal = Ws × 0.2390057361. To convert watt seconds to calories first substitute the watt second value into the above formula, and then execute the calculation. If we wanted to calculate 1 watt second in calories we follow these steps:
cal = Ws × 0.2390057361
cal = 1 × 0.2390057361
cal = 0.2390057361
Or in other words, 1 watt second is equal to 0.2390057361 calories.
