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.
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 btu per hour (it) to metric horsepower (ps/cv)
1 btu per hour (it) is equal to 0.00039846576241 metric horsepower (ps/cv) when both are expressed in watt-equivalents:
1 btu_hr = (0.2930710701722222 W ÷ 735.49875 W) ps = 0.00039846576241 ps
Each btu per hour (it) is defined as 0.2930710701722222 W and each metric horsepower (ps/cv) as 735.49875 W in this tool, so one btu_hr equals 0.2930710701722222 ÷ 735.49875 ps = 0.00039846576241 ps.
Let d(btu_hr) be the numeric value in BTU per Hour (IT) (btu_hr), and d(ps) the value in Metric Horsepower (PS/CV) (ps). Then:
d(ps) = d(btu_hr) × (0.2930710701722222 / 735.49875)
Equivalently, divide by how many btu_hr fit into one ps (watts per ps divided by watts per btu_hr):
d(ps) = d(btu_hr) ÷ 2509.62590598855968
Or: metric horsepower (ps/cv) = btu per hour (it) ÷ 2509.62590598855968
Examples
Example #1: Convert 1 btu_hr to metric horsepower (ps/cv)
1 btu_hr = 1 btu_hr × (0.2930710701722222/735.49875) ps = 0.0003984658 ps
1 btu_hr = 1 btu_hr ÷ 2509.62590598855968 = 0.0003984658 ps
Intermediate watts: 0.2930710702 W
Example #2: Convert 10 btu_hr to metric horsepower (ps/cv)
10 btu_hr = 10 btu_hr × (0.2930710701722222/735.49875) ps = 0.0039846576 ps
10 btu_hr = 10 btu_hr ÷ 2509.62590598855968 = 0.0039846576 ps
Intermediate watts: 2.9307107017 W
Summary
To convert BTU per Hour (IT) to Metric Horsepower (PS/CV), multiply the value in btu_hr by the ratio of watts per btu_hr divided by watts per ps. Equivalently: value_ps = value_btu_hr × (0.2930710701722222 / 735.49875). Numerically, 1 btu_hr equals 0.00039846576241254285 ps.
Relationship context
You are converting between thermal engineering rates (BTU/h, kcal/h) (BTU per Hour (IT)) and mechanical power (horsepower, ft·lb/s) (Metric Horsepower (PS/CV)). All linear values are mapped through watts first. The numeric factor is 3.984658e-4.
