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.
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.
How to convert kilocalories per hour (thermochemical) to metric horsepower (ps/cv)
1 kilocalorie per hour (thermochemical) is equal to 0.00158018245744 metric horsepower (ps/cv) when both are expressed in watt-equivalents:
1 kcal_h = (1.1622222222222223 W ÷ 735.49875 W) ps = 0.00158018245744 ps
Each kilocalorie per hour (thermochemical) is defined as 1.1622222222222223 W and each metric horsepower (ps/cv) as 735.49875 W in this tool, so one kcal_h equals 1.1622222222222223 ÷ 735.49875 ps = 0.00158018245744 ps.
Let d(kcal_h) be the numeric value in Kilocalorie per Hour (thermochemical) (kcal_h), and d(ps) the value in Metric Horsepower (PS/CV) (ps). Then:
d(ps) = d(kcal_h) × (1.1622222222222223 / 735.49875)
Equivalently, divide by how many kcal_h fit into one ps (watts per ps divided by watts per kcal_h):
d(ps) = d(kcal_h) ÷ 632.83831261950286
Or: metric horsepower (ps/cv) = kilocalorie per hour (thermochemical) ÷ 632.83831261950286
Examples
Example #1: Convert 1 kcal_h to metric horsepower (ps/cv)
1 kcal_h = 1 kcal_h × (1.1622222222222223/735.49875) ps = 0.0015801825 ps
1 kcal_h = 1 kcal_h ÷ 632.83831261950286 = 0.0015801825 ps
Intermediate watts: 1.1622222222 W
Example #2: Convert 10 kcal_h to metric horsepower (ps/cv)
10 kcal_h = 10 kcal_h × (1.1622222222222223/735.49875) ps = 0.0158018246 ps
10 kcal_h = 10 kcal_h ÷ 632.83831261950286 = 0.0158018246 ps
Intermediate watts: 11.6222222222 W
Summary
To convert Kilocalorie per Hour (thermochemical) to Metric Horsepower (PS/CV), multiply the value in kcal_h by the ratio of watts per kcal_h divided by watts per ps. Equivalently: value_ps = value_kcal_h × (1.1622222222222223 / 735.49875). Numerically, 1 kcal_h equals 0.0015801824574443156 ps.
Relationship context
