How it is calculated
The thermochemical calorie in this set is 4,184 J, and the kilocalorie is 4184 J. A kilowatt-hour is 3,6 million joules. On a food label, “calorie” often already means a kilocalorie.
Result = value × factor of the source unit / factor of the target unit
Where the numbers come from
- Value
- Source unit
Example
1 kWh = 860 kcal, rounded. More precisely 3 600 000 / 4184.
Questions
Is a calorie on the label a kcal?
For food, almost always yes. If the pack says 250 kcal, enter kilocalories, not small calories.
Why BTU?
Air conditioners and boilers are sometimes marked this way. The conversion lets you compare with watts, if you then multiply energy by time yourself.
Is power converted too?
Watts and horsepower live in the power converter. Here there is only energy, already multiplied by time.
