About Metric Horsepower (PS/CV)
PS is metric horsepower (also called Pferdestarke), defined as 735.49875 W. It appears widely in EU and Korean vehicle specs.
About Kilocalorie per Hour (thermochemical)
Kilocalories per hour is a thermal power rate using the thermochemical kilocalorie (4,184 J per kcal) spread over one hour.
How to convert metric horsepower (ps/cv) to kilocalories per hour (thermochemical)
1 metric horsepower (ps/cv) is equal to 632.83831261950286 kilocalorie per hour (thermochemical) when both are expressed in watt-equivalents:
1 ps = (735.49875 W ÷ 1.1622222222222223 W) kcal_h = 632.83831261950286 kcal_h
Each metric horsepower (ps/cv) is defined as 735.49875 W and each kilocalorie per hour (thermochemical) as 1.1622222222222223 W in this tool, so one ps equals 735.49875 ÷ 1.1622222222222223 kcal_h = 632.83831261950286 kcal_h.
Let d(ps) be the numeric value in Metric Horsepower (PS/CV) (ps), and d(kcal_h) the value in Kilocalorie per Hour (thermochemical) (kcal_h). Then:
d(kcal_h) = d(ps) × (735.49875 / 1.1622222222222223)
Equivalently, divide by how many ps fit into one kcal_h (watts per kcal_h divided by watts per ps):
d(kcal_h) = d(ps) ÷ 0.00158018245744
Or: kilocalorie per hour (thermochemical) = metric horsepower (ps/cv) ÷ 0.00158018245744
Examples
Example #1: Convert 1 ps to kilocalorie per hour (thermochemical)
1 ps = 1 ps × (735.49875/1.1622222222222223) kcal_h = 632.83831262 kcal_h
1 ps = 1 ps ÷ 0.00158018245744 = 632.83831262 kcal_h
Intermediate watts: 735.49875 W
Example #2: Convert 10 ps to kilocalorie per hour (thermochemical)
10 ps = 10 ps × (735.49875/1.1622222222222223) kcal_h = 6328.3831262 kcal_h
10 ps = 10 ps ÷ 0.00158018245744 = 6328.3831262 kcal_h
Intermediate watts: 7,354.9875 W
Summary
To convert Metric Horsepower (PS/CV) to Kilocalorie per Hour (thermochemical), multiply the value in ps by the ratio of watts per ps divided by watts per kcal_h. Equivalently: value_kcal_h = value_ps × (735.49875 / 1.1622222222222223). Numerically, 1 ps equals 632.8383126195029 kcal_h.
Relationship context
You are converting between mechanical power (horsepower, ft·lb/s) (Metric Horsepower (PS/CV)) and thermal engineering rates (BTU/h, kcal/h) (Kilocalories per Hour (thermochemical)). All linear values are mapped through watts first. The numeric factor is 6.328383e+2.
