Enter the Energy Efficiency Ratio (EER) and the Cooling Capacity in BTU/hr into the calculator to convert EER to kW per ton of cooling capacity. This calculator helps in determining the efficiency of air conditioning systems.

## EER to kW Ton Formula

The following formula is used to convert EER to kW per ton of cooling capacity:

kW/Ton = (12 / EER) * (Cooling Capacity / 12000)

Variables:

- kW/Ton is the power usage in kilowatts for each ton of cooling capacity.
- EER is the Energy Efficiency Ratio, which is the ratio of the cooling capacity (in BTU/hr) to the power input (in watts).
- Cooling Capacity is the amount of heat removed by the air conditioning system (in BTU/hr).

To convert EER to kW per ton, divide 12 by the EER, then multiply the result by the cooling capacity divided by 12,000.

## What is EER?

Energy Efficiency Ratio (EER) is a measure of how efficiently a cooling system operates when the outdoor temperature is at a specific level (usually 95°F). A higher EER rating indicates a more efficient air conditioning system. EER is calculated by dividing the cooling capacity in British Thermal Units (BTU) per hour by the power input in watts.

## How to Calculate kW/Ton from EER?

The following steps outline how to calculate kW per ton from EER.

- First, determine the Energy Efficiency Ratio (EER) of the air conditioning system.
- Next, determine the cooling capacity of the system in BTU/hr.
- Use the formula above to calculate the kW per ton: kW/Ton = (12 / EER) * (Cooling Capacity / 12000).
- Finally, enter the EER and cooling capacity into the calculator to get the kW per ton value.

**Example Problem :**

Use the following variables as an example problem to test your knowledge.

Energy Efficiency Ratio (EER) = 10

Cooling Capacity = 24000 BTU/hr
