Convert steps climbed to flights of stairs and effort.
Converting steps to flights is simply a division by steps per flight, but the effort depends on height rather than step count. Multiplying the number of steps by the rise of each gives vertical metres, and the mechanical work of lifting your body that far is weight times gravity times height. That work figure is why stair climbing is a far stronger stimulus than walking the same distance on the flat.
Flights and vertical work
Flights = steps climbed / steps per flight; vertical metres = steps x rise in cm / 100; work in kJ = body weight x 9.81 x vertical metres / 1000
These figures are estimates based on population-average formulas and are intended for training and recreational planning only. They are not medical advice. Consult a qualified health professional before starting or changing an exercise programme, particularly if you have an existing medical condition.
Fitness trackers commonly treat 10-16 steps or about three metres of climb as one flight. Residential flights are usually 12-14 steps.
Because human movement is only about 20-25% efficient. The metabolic cost of climbing is roughly four to five times the mechanical work shown here.
Yes — it sets the vertical distance. Deep steps demand more work per step and load the hips and knees more heavily.
