Exercise Calorie Burn (METs) Mathematics

Calories burned calculator computes energy expenditure from activity type, duration, and body weight using the Metabolic Equivalent of Task (MET) formula.

Standardized Mathematical Formula
Calories = MET × Weight (kg) × Duration (hours)

A MET (Metabolic Equivalent of Task) measures how many times more energy an activity uses compared to resting. Multiplying MET value by bodyweight and duration in hours gives total calories burned.

Variables:
MET:Activity intensity multiplier (e.g. running ≈ 9.8, walking ≈ 4.3)
Weight:Body weight in kilograms
Duration:Activity duration in hours
How It Works (Step-by-Step)
  • 1Select an activity (its MET value is applied automatically) and enter your body weight and duration.
  • 2View total calories burned for that session.
Real-World Numerical Example
Running at 6.0 mph for 45 Minutes

A 75 kg person runs at 6.0 mph (MET = 9.8) for 45 minutes.

•Duration in hours: 45 ÷ 60 = 0.75 h.
•Calories: 9.8 × 75 × 0.75 = 551.25 kcal.
Result: The session burns approximately 551 calories.
Calculation Best Practices & Tips
Use the Brzycki formula (1RM = Weight / (1.0278 - 0.0278 * Reps)) for sub-maximal sets between 2 and 10 repetitions.
Pace consistency during the first half of a marathon is the single greatest predictor of achieving personal record finish times.

Frequently Asked Questions (FAQ)

1 MET is defined as the energy cost of sitting quietly (approximately 3.5 mL of oxygen per kg of body weight per minute). An activity with a MET of 8 burns roughly 8 times as much energy as resting.

Yes — since the MET formula multiplies by body weight directly, a heavier person burns proportionally more calories performing the identical activity for the identical duration.
