🏃BMI & Calorie Calculator Documentation & Guide
Calculators
The BMI & Calorie Calculator computes your Body Mass Index (BMI), WHO weight classification, Basal Metabolic Rate (BMR), and Total Daily Energy Expenditure (TDEE) based on your height, weight, age, biological sex, and physical activity level.
📋How to Use This Tool
- Enter Body Metrics: Input your height in centimeters (cm), weight in kilograms (kg), age, and gender.
- Select Activity Level: Choose the activity multiplier that best matches your weekly exercise routine.
- Calculate Metrics: Click Calculate BMI & Calories to generate your BMI score, TDEE maintenance calories, and target intake guide.
- Copy Summary: Click 📋 Copy to save your complete health and calorie breakdown to your clipboard.
⚙️Technical & Educational Details
Uses the World Health Organization (WHO) BMI formula and the Mifflin-St Jeor equation for daily energy expenditure:
• BMI: Weight (kg) ÷ [ Height (m) ]²
• BMR (Male): (10 × kg) + (6.25 × cm) − (5 × age) + 5
• BMR (Female): (10 × kg) + (6.25 × cm) − (5 × age) − 161
• TDEE: BMR × Activity Multiplier (1.2 to 1.9)
💡Practical Use Cases & Best Practices
- Setting daily calorie targets for sustainable weight loss (−500 kcal/day) or lean muscle gain (+300 kcal/day).
- Checking healthy weight ranges (18.5–24.9 BMI) for your specific height.
- Comparing resting metabolic burn (BMR) against active daily expenditure (TDEE).
