## CFM Per Ton Formula

The following formula is used to calculate the total cubic feet per minute per ton of cooling.

CFPT = CFM / C

- Where CFPT is the cubic feet per minute per ton
- CFM is the cubic feet per minute
- C is the tonnage of cooling.

## CFM Per Ton Definition

**What is CFM per ton? **

CFM per ton, which stands for cubic feet per minute per ton, is a measure of the amount of air an air-conditioner can cool per tonnage of cooling.

## Example Problem

**how to calculate CFM per ton? **

First, determine the total cubic feet per minute of air moving through an area. In this example, the fans are moving the air at a rate of 450 CFM.

Next, determine the total tonnage of cooling required for that air. In this case, we will use an average of 4 tons.

Finally, calculate the CFM per ton using the formula above:

CFPT = CFM / C

CFPT = 450 / 4

CFPT = 112.5 CFM /ton
