Human efficiency≈ 23%
Step heightTypically 17 cm
One floor≈ 3 m
Descending≈ ⅓ of climbing

The maths behind it

This tool uses Useful work = weight × gravity × height gained. Calories = that ÷ 23% human efficiency. Descending costs about a third of climbing. Every intermediate value is shown on screen, so the result can be checked by hand.

Only about 23% of the energy burned becomes useful lifting work; the rest leaves as heat, which is why stairs feel harder than the physics suggests. Descending is where most stair injuries happen, because the muscles resist the fall rather than driving the lift.
