Convert Calories per Second to Electrical Horsepower
Convert Calories per Second (cal/s) to Electrical Horsepower (hp(E)) instantly and accurately.
Conversion Formula
hp(E) = cal/s × 0.00561233244
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 Electrical Horsepower
The electrical horsepower (hp(E)) is defined as exactly 746 W - the US NEMA rounding used on electric motor nameplates. It differs from mechanical hp (745.7 W) by only 0.04%. Every NEMA-rated motor in the US carries a horsepower nameplate: a '5 hp motor' delivers 5 × 746 = 3,730 W. NEC motor branch-circuit sizing tables, overload relay selection, and starter ratings are all based on hp(E). Despite global kW adoption, US industrial motor infrastructure remains standardised in electrical horsepower. 1 hp(E) = 746 W.
