Convert BTU per Minute to Kilocalories per Hour
Convert BTU per Minute (BTU/min) to Kilocalories per Hour (kcal/h) instantly and accurately.
Conversion Formula
kcal/h = BTU/min × 15.11974567
About BTU per Minute
One BTU per minute (BTU/min) ≈ 17.58 W. Fire engineering uses BTU/min for heat release rate (HRR): a burning sofa releases 500-5,000 BTU/min; a flashover room fire 50,000-500,000 BTU/min. US commercial gas burners are rated 500-2,000 BTU/min. NFPA fire suppression standards use BTU/min to match sprinkler flow to HRR. Industrial furnace heating cycles also use this unit. 1 BTU/min = 17.584 W.
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.
