How to Convert Calories to Stones

Scales are used to measure weight

To convert a calorie measurement to a stone measurement, divide the weight by the conversion ratio.

Since one stone is equal to 49,000 calories, you can use this simple formula to convert:

stones = calories ÷ 49,000

The weight in stones is equal to the calories divided by 49,000.

Calories can be abbreviated as kcal; for example, 1 calorie can be written as 1 kcal.


One stone is equal to 14 pounds and is mostly used in the United Kingdom and Ireland as a unit of mass. It's most commonly used to measure personal body weight.[3]
