The maths behind it

This tool uses ACSM walking equation: VO₂ = 3.5 + 0.1 × speed + 1.8 × speed × grade, in ml/kg/min. Calories = VO₂ × weight ÷ 200. Every intermediate value is shown on screen, so the result can be checked by hand.

Walking at the same speed up a 5% grade roughly doubles the energy cost, which is why a hilly route beats a longer flat one for the same time. The equation is the ACSM standard for 3–6 km/h and becomes unreliable outside that range.

What are the key numbers for the Walking Calories Calculator?
Valid range is 3–6 km/h. 5% incline is Roughly doubles the cost. 1 MET is 3.5 ml/kg/min. These are printed on the page itself, so you do not have to take them on trust.
Can I rely on this for exact work?
The calculation runs in double precision and the result is shown to ten significant figures, so converting a value and converting it back returns the original. What is displayed is rounded for readability; what is copied is not.
