This calculator estimates the calories you burn walking based on your pace, body weight, incline, and time. It uses the ACSM walking equation rather than a flat lookup, so a brisk uphill walk shows a higher burn than a slow stroll on flat ground. Enter your weight in pounds or kilograms.
How this is calculated
It applies the American College of Sports Medicine walking metabolic equation: oxygen use VO2 (ml/kg/min) equals 3.5 plus 0.1 times speed in metres per minute plus 1.8 times speed times the fractional grade. Calories per minute equal VO2 times body weight in kilograms divided by 200, using the standard 5 kcal per litre of oxygen. The equation is validated for typical walking speeds of about 2 to 4 mph.
How to use
- Enter your walking speed in miles per hour.
- Enter your body weight and choose pounds or kilograms.
- Set the incline percent and duration, then read the calories burned.
Examples
- 3.0 mph, 70 kg, 45 min, flat:
about 182 calories - 3.5 mph, 180 lb, 30 min, 5% incline:
about 261 calories
FAQ
- Does incline really matter that much?
- Yes. Walking uphill sharply raises oxygen demand, so a 5 percent grade can lift your calorie burn well above the same walk on flat ground. The ACSM equation accounts for grade directly.
- Is this exact?
- It is a solid estimate. Real burn varies with fitness, terrain, gait, and metabolism. The ACSM equation is a peer-reviewed standard, but treat the number as a close approximation, not a precise measurement.
- What is a MET?
- A MET is a multiple of your resting metabolic rate. The calculator reports the MET value of your walk so you can compare intensities; 1 MET is sitting quietly, and brisk walking is roughly 3 to 5 METs.
