Convert Foot-Pounds per Minute to Kilocalories per Hour
Convert Foot-Pounds per Minute (ft⋅lbf/min) to Kilocalories per Hour (kcal/h) instantly and accurately.
Conversion Formula
kcal/h = ft⋅lbf/min × 0.01942989321
About Foot-Pounds per Minute
One foot-pound per minute (ft·lbf/min) ≈ 0.02260 W. Its historical importance is large: James Watt rated mill horses at ~33,000 ft·lbf/min sustained output and defined 1 mechanical horsepower as exactly 33,000 ft·lbf/min (= 550 ft·lbf/s). The unit is still used for machine-tool power, hydraulic pump output, and low-speed actuator performance in US customary calculations: torque (ft·lbf) × RPM = power in ft·lbf/min. 1 hp = 33,000 ft·lbf/min.
About Kilocalories per Hour
One kilocalorie per hour (kcal/h) equals exactly 1.163 W. It is the natural unit for human metabolic rate: sedentary adult ~60-70 kcal/h; walking 250-350 kcal/h; vigorous cycling 500-700 kcal/h; competitive rowing ~1,200 kcal/h. Treadmills and exercise bikes display kcal/h directly. Industrial drying and evaporation calcs in older metric systems (especially Asia) used kcal/h for heat duty; 1 Mcal/h = 1.163 kW. 1 kcal/h = 1.163 W.
