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 BTU per Hour (IT)
BTU per hour expresses thermal power using the IT British thermal unit (≈ 1,055.056 J per BTU), divided by one hour. Common in HVAC equipment ratings.
How to convert metric horsepower (ps/cv) to btu per hour (it)
1 metric horsepower (ps/cv) is equal to 2509.62590598855968 btu per hour (it) when both are expressed in watt-equivalents:
1 ps = (735.49875 W ÷ 0.2930710701722222 W) btu_hr = 2509.62590598855968 btu_hr
Each metric horsepower (ps/cv) is defined as 735.49875 W and each btu per hour (it) as 0.2930710701722222 W in this tool, so one ps equals 735.49875 ÷ 0.2930710701722222 btu_hr = 2509.62590598855968 btu_hr.
Let d(ps) be the numeric value in Metric Horsepower (PS/CV) (ps), and d(btu_hr) the value in BTU per Hour (IT) (btu_hr). Then:
d(btu_hr) = d(ps) × (735.49875 / 0.2930710701722222)
Equivalently, divide by how many ps fit into one btu_hr (watts per btu_hr divided by watts per ps):
d(btu_hr) = d(ps) ÷ 0.00039846576241
Or: btu per hour (it) = metric horsepower (ps/cv) ÷ 0.00039846576241
Examples
Example #1: Convert 1 ps to btu per hour (it)
1 ps = 1 ps × (735.49875/0.2930710701722222) btu_hr = 2509.62590599 btu_hr
1 ps = 1 ps ÷ 0.00039846576241 = 2509.62590599 btu_hr
Intermediate watts: 735.49875 W
Example #2: Convert 10 ps to btu per hour (it)
10 ps = 10 ps × (735.49875/0.2930710701722222) btu_hr = 25096.2590599 btu_hr
10 ps = 10 ps ÷ 0.00039846576241 = 25096.2590599 btu_hr
Intermediate watts: 7,354.9875 W
Summary
To convert Metric Horsepower (PS/CV) to BTU per Hour (IT), multiply the value in ps by the ratio of watts per ps divided by watts per btu_hr. Equivalently: value_btu_hr = value_ps × (735.49875 / 0.2930710701722222). Numerically, 1 ps equals 2509.6259059885597 btu_hr.
Relationship context
You are converting between mechanical power (horsepower, ft·lb/s) (Metric Horsepower (PS/CV)) and thermal engineering rates (BTU/h, kcal/h) (BTU per Hour (IT)). All linear values are mapped through watts first. The numeric factor is 2.509626e+3.
