Calories Burned Calculation Results
How the calculation works
Gross calories (kcal) = MET × weight (kg) × duration (hours). This estimate includes resting energy during exercise. Additional calories above rest are approximated as (MET - 1) × weight × hours. MET values are representative averages and vary by effort and individual.
Not medical advice. Consult a healthcare professional before beginning vigorous activity if you have relevant medical conditions.
Frequently Asked Questions
What is MET?
MET stands for Metabolic Equivalent of Task and represents activity intensity relative to resting metabolism.
Are calories burned exact?
No. These are estimates. Fitness, pace, terrain and individual differences affect actual energy use.
Does the estimate include resting energy?
Yes. The standard MET formula estimates gross energy expenditure during the activity.
Does body weight affect the result?
Yes. At the same MET and duration, higher body weight produces a higher estimated energy expenditure.
Can I use this for walking?
Yes. Select the walking activity that most closely matches your effort.
Does this replace a fitness tracker?
No. Both MET calculators and wearables produce estimates with different limitations.
Can I use it for weight loss planning?
It may help illustrate activity energy use, but it is not a personalised weight management prescription.
