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 Ton of Refrigeration (TR)
One ton of refrigeration (TR) equals 12,000 BTU/h (IT), approximately 3,516.85 W. It is widely used in HVAC and refrigeration sizing.
How to convert metric horsepower (ps/cv) to tons of refrigeration (tr)
1 metric horsepower (ps/cv) is equal to 0.20913549216571 ton of refrigeration (tr) when both are expressed in watt-equivalents:
1 ps = (735.49875 W ÷ 3,516.8528420666667 W) tr = 0.20913549216571 tr
Each metric horsepower (ps/cv) is defined as 735.49875 W and each ton of refrigeration (tr) as 3,516.8528420666667 W in this tool, so one ps equals 735.49875 ÷ 3,516.8528420666667 tr = 0.20913549216571 tr.
Let d(ps) be the numeric value in Metric Horsepower (PS/CV) (ps), and d(tr) the value in Ton of Refrigeration (TR) (tr). Then:
d(tr) = d(ps) × (735.49875 / 3,516.8528420666667)
Equivalently, divide by how many ps fit into one tr (watts per tr divided by watts per ps):
d(tr) = d(ps) ÷ 4.78158914895051
Or: ton of refrigeration (tr) = metric horsepower (ps/cv) ÷ 4.78158914895051
Examples
Example #1: Convert 1 ps to ton of refrigeration (tr)
1 ps = 1 ps × (735.49875/3,516.8528420666667) tr = 0.2091354922 tr
1 ps = 1 ps ÷ 4.78158914895051 = 0.2091354922 tr
Intermediate watts: 735.49875 W
Example #2: Convert 10 ps to ton of refrigeration (tr)
10 ps = 10 ps × (735.49875/3,516.8528420666667) tr = 2.0913549217 tr
10 ps = 10 ps ÷ 4.78158914895051 = 2.0913549217 tr
Intermediate watts: 7,354.9875 W
Summary
To convert Metric Horsepower (PS/CV) to Ton of Refrigeration (TR), multiply the value in ps by the ratio of watts per ps divided by watts per tr. Equivalently: value_tr = value_ps × (735.49875 / 3516.8528420666667). Numerically, 1 ps equals 0.2091354921657133 tr.
Relationship context
You are converting between mechanical power (horsepower, ft·lb/s) (Metric Horsepower (PS/CV)) and apparent power at unity PF (VA) (Tons of Refrigeration (TR)). All linear values are mapped through watts first. The numeric factor is 2.091355e-1.
