BMR per Kilogram
You cannot compare two people’s BMR directly when they weigh different amounts. Dividing by weight puts them on one scale; most adults land near 20 kcal per kilogram.

What it means
22.86 kcal per kilogram is on the high side — more muscle or a younger body.
Formula
Calories per kg = BMR ÷ Weight (kg)
Muscle burns more than fat, so a lower body-fat percentage raises this. At the same weight, a higher figure means more muscle.

Frequently asked questions
Q. How is BMR per Kilogram calculated?
Calories per kg = BMR ÷ Weight (kg) — You cannot compare two people’s BMR directly when they weigh different amounts. Dividing by weight puts them on one scale; most adults land near 20 kcal per kilogram.
Q. Can you walk through an example?
With BMR 1,600kcal, Weight (kg) 70kg, the answer is Calories per kg 22.86kcal.
Q. What do I need to enter?
Enter BMR, Weight (kg). The result recalculates as you type, and an empty box counts as zero.
Q. How much does the answer move if I change a number?
Changing only BMR (kcal) moves the answer to BMR (kcal) 800 → Calories per kg (kcal) 11.43 and BMR (kcal) 3,200 → Calories per kg (kcal) 45.71. The table below lays out five steps.
Q. How are the numbers rounded?
Money is shown to the nearest whole unit, percentages to one decimal place and everything else to two. What you see is rounded; the calculation itself carries the unrounded value forward.
