Basal Metabolic Rate Calculator Online-summary

The online basal metabolic rate calculator (BMR calculator) uses multiple formulas to calculate the body's basal metabolic rate based on parameters such as height, weight, and age, and supports evaluating the daily calorie consumption of the body under different exercise states.

Basal Metabolic Rate Calculator Online-instructions

The online basal metabolic rate (BMR) calculator calculates the BMR using different formulas based on parameters such as height, weight, age, and body fat percentage. Assess the daily calorie expenditure based on basal metabolic rate and daily exercise status.

1. You burn calories even when resting through basic life-sustaining functions like breathing, circulation, nutrient processing, and cell production. This is known as basal metabolic rate (BMR).
2. In the following calculation formula, m is the body weight in kilograms. h is height, measured in centimeters. a represents age. f is the body fat percentage, expressed in %.
3. Harris–Benedict Formula : The BMR calculation formula, first proposed in 1919, is widely used due to its early introduction. The calculation formula is: for men, BMR = (13.7516m + 5.0033h - 6.7550a + 66.4730) kcal/day . for women, BMR = (9.5634m + 1.8496h - 4.6756a + 655.0955) kcal/day .
4. Revised Harris–Benedict Formula : In 1984, it was proposed to improve the parameters of the Harris Benedict formula with new data to achieve better accuracy. The calculation formula is: for men, BMR = (13.397m + 4.799h - 5.677a + 88.362) kcal/day . for women, BMR = (9.247m + 3.098h - 4.330a + 447.593) kcal/day .
5. Mifflin St Jeor Formula : Proposed in 1990, the calculated BMR has higher accuracy. It is recommended to use this formula to calculate BMR. The calculation formula is: for men, BMR = (10.0m + 6.25h - 5.0a +5) kcal/day . for women, BMR = (10.0m + 6.25h - 5.0a -161) kcal/day .
6. Katch–McArdle Formula : This formula is commonly used to calculate resting metabolic rate (RMR). The calculation formula is: e = m(1 - f/100) , BMR = 370 + 21.6e .
