Heat flow
- Thermochemical Calorie per Second (cal(th)/s)
- 239.006
- Thermochemical Kilocalorie per Hour (kcal(th)/h)
- 860.421
- International Table Kilocalorie per Hour (kcal(IT)/h)
- 859.845
- British Thermal Unit (IT) per Hour (BTU(IT)/h)
- 3,412.14
- Thermochemical British Thermal Unit per Hour (BTU(th)/h)
- 3,414.43
- British Thermal Unit (IT) per Second (BTU(IT)/s)
- 0.947817
Thermochemical calorie per second: 1 cal(th)/s = 4.184 W
1 kcal(th)/h = 4184 / 3600 W
1 kcal(IT)/h = 4186.8 / 3600 W
1 BTU(IT)/h = 1055.05585262 / 3600 W
1 BTU(th)/h = 1054.35026444 / 3600 W
1 BTU(IT)/s = 1055.05585262 W
Horsepower
- Mechanical Horsepower (hp(mech))
- 1.34102
- Metric Horsepower (PS)
- 1.35962
- Electric Horsepower (hp(elec))
- 1.34048
- Boiler Horsepower (hp(boiler))
- 0.101942
Mechanical horsepower: 1 hp(mech) = 550 ft·lbf/s
Metric horsepower: 1 PS = 75 kgf·m/s = 735.49875 W
Electric horsepower: 1 hp(elec) = 746 W
Boiler horsepower: 1 hp(boiler) = 9809.5 W
Mechanical rate
- Foot-pound Force per Second (ft·lbf/s)
- 737.562
- Foot-pound Force per Minute (ft·lbf/min)
- 44,253.7
- Kilogram-force Metre per Second (kgf·m/s)
- 101.972
Derived from the international pound, foot, and g₀
1 ft·lbf/min = ft·lbf/s / 60
1 kgf·m/s = 9.80665 W
Refrigeration
- Ton of Refrigeration (TR)
- 0.284345
1 TR = 12000 BTU(IT)/h; the unit describes power, not mass
CGS
- Erg per Second (erg/s)
- 10,000,000,000
1 erg/s = 10^-7 W
