Estimate Jacobs Ladder calories or target time from body weight, with optional climbed-feet and average-pace supporting metrics.
How the Jacobs Ladder Calorie Calculator Works
The calculator uses the 2024 Adult Compendium stair-treadmill ergometer category as a 9.3-MET proxy. This is not a validated Jacobs Ladder calibration. Optional machine climb pace or distance provides supporting metrics without changing calories.
Formula: gross kcal = 9.3 x 3.5 x body weight in kg / 200 x minutes
What the Results Show
The primary answer is calories or target duration. Secondary results include energy above standard resting expenditure, gross rate per minute, MET-minutes, and optional machine distance or average pace.
Why This Calculator Is Different
It avoids a universal climb-rate calorie formula because ladder-machine energy cost changes nonlinearly and users adapt differently to the moving ladder.
Assumptions and Limitations
The 9.3-MET value represents general stair-treadmill work. Hand support, cadence, technique, and conditioning influence actual energy expenditure. This calculator supports adult body weights of 35–225 kg and durations up to 120 minutes, including reverse-solved durations. Zero duration or a zero calorie target gives zero energy or time; it does not define a pace from distance.
