How it is calculated
The metric horsepower used in vehicle specifications is 735,49875 W. Mechanical hp is a little higher, about 745,7 W. Calories per hour are a power, not a store of energy.
Result = value × factor of the source unit / factor of the target unit
Where the numbers come from
- Value

Example
1 kW ≈ 1,3596 PS. 10 PS ≈ 7,355 kW.
Questions
Which horsepower is in an engine specification?
Usually metric. Mechanical hp is marked separately.
Is the kilowatt-hour here too?
No. A kilowatt-hour is energy. It is in the energy converter.
Where do the calories per hour come from?
That is sometimes how heating power is written. It is a calorie divided by an hour, not the kilocalorie on a food label.
