Convert Calories per Second to BTU per Minute
Convert Calories per Second (cal/s) to BTU per Minute (BTU/min) instantly and accurately.
Conversion Formula
BTU/min = cal/s × 0.2380992432
About Calories per Second
One calorie per second (cal/s) = exactly 4.1868 W. It bridges thermochemistry and power: bomb calorimeters and reaction calorimeters characterise exothermic events by cal/s during the reaction interval. Food science uses cal/s to model heat transfer into food during frying or roasting. Since 1 kcal/s = 4,186.8 W, kilocalories per second appear in high-intensity industrial dryers and continuous-flow reactor heat duties. 1 cal/s = 4.1868 W.
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.
