Metric (kg/cm)
Imperial (lbs/ft)
How to Use the BMR Calculator
Your Basal Metabolic Rate (BMR) represents the number of calories your body needs to maintain basic physiological functions at rest.
- Choose Your Units: Select between Metric (kg/cm) or Imperial (lbs/ft) measurements at the top.
- Enter Your Information: Fill in your gender, age, weight, and height. All fields are required for accurate calculation.
- Calculate Your BMR: Click the "Calculate BMR" button to see your results instantly.
- View Activity Levels: See your total daily calorie needs based on different activity levels, from sedentary to super active.
- Plan Your Diet: Use these numbers to plan your daily caloric intake for weight maintenance, loss, or gain.
Understanding Your Results
The calculator uses the Mifflin-St Jeor equation, which is considered one of the most accurate BMR formulas. Your BMR is then multiplied by activity factors to estimate your Total Daily Energy Expenditure (TDEE).

- Sedentary: Desk job, little to no exercise
- Light Activity: Light exercise 1-3 days per week
