📐 How It Works: Behind the Scenes

Our calories burn calculator uses the scientifically accepted MET (Metabolic Equivalent of Task) formula:

Calories Burned = MET × Weight (kg) × Duration (hours)

Where:

• MET = Energy cost of an activity (e.g., walking = 3.5, running = 8.0)
• Weight = In kilograms (converted if in lbs)
• Duration = In hours (converted from minutes)

Example:
A 70 kg person does 30 minutes (0.5 hrs) of cycling (MET = 8.0)
= 8.0 × 70 × 0.5 = 280 kcal burned

All calculations are:

• ✅ Accurate and instant
• ✅ Based on CDC and ACSM standards
• ✅ Adjustable for real-world conditions

Our calories burn calculator does this — accurately and instantly.
