Coefficient of performance to kilowatts per ton
Type a value in COP to get it in kW/ton instantly.
0.2931kW/ton
That's 2× as efficient as a large office chiller, while the theoretical limit for a 20 °C lift is 1.22× more efficient. Every kWh of electricity moves 12 kWh of heat.
Convert the other way: kW/ton to COP
What it means
How efficient is that?
These are steady-state ratings. Seasonal figures such as SEER and SCOP average over a whole year of weather and cannot be converted exactly from a single rating.
The math
How to convert COP to kW/ton
EER = COP × 3.412 (BTU per watt-hour), and kW/ton = 3.517 ÷ COP.
Example: 12 COP = 0.293071 kW/ton.

Coefficient of performance (COP)
Heat moved per unit of electricity, in the same units.
Kilowatts per ton (kW/ton)
Chiller plants: electricity per ton of cooling. Lower is better.
