Steps to Calories Calculator (calories burned walking & food equivalent)

How it works

Distance = steps × step length. Speed S in metres per minute = km/h × 1000 ÷ 60, and time = distance ÷ S. The ACSM walking equation gives oxygen use on level ground: VO₂ = 0.1 × S + 3.5 mL/kg/min, where 3.5 is the resting part. About 5 kcal are burned per litre of oxygen, so gross kcal = VO₂ × weight ÷ 1000 × 5 × minutes, and the net calories from walking leave out the resting 3.5. The equation is meant for speeds of 50–100 m/min (3–6 km/h) on flat ground; hills, stairs and carrying loads burn more.

FAQ

Why are net calories lower than my fitness tracker shows?

Many trackers report gross calories, which include what you would burn sitting still. Net calories are only the extra energy the walk took, which is the fair number to compare with food.

Does walking faster burn more per step?

On flat ground the equation’s net cost depends on distance and weight, not speed, so 10,000 steps cost about the same net calories at 4 or 5 km/h. Hills and stairs raise the cost a lot.

Checked 11 Nov 2026. American College of Sports Medicine, “ACSM’s Guidelines for Exercise Testing and Prescription” (Wolters Kluwer), metabolic calculations — walking equation VO₂ = 0.1 × speed + 1.8 × speed × grade + 3.5 mL/kg/min (valid 50–100 m/min); ≈5 kcal per litre of O₂.
