When you’re sizing an HVAC system, CFM per ton is key. CFM stands for cubic feet per minute, which measures airflow. Tons show cooling capacity. Matching these ensures efficient cooling.
How to Convert CFM to Tons: A Step-by-Step Guide
Here’s how you find tons from CFM:
- Divide total CFM by airflow per ton (400 CFM).

Example |
Identify Total CFM |
Note the total CFM of the system. |
1200 CFM |
Divide by Standard CFM |
Use 400 CFM per ton. |
1200 ÷ 400 = 3 tons |
For larger systems, follow the same steps for each zone
CFM per Ton of Cooling: Explained for HVAC Systems
In HVAC, the standard airflow is 400 CFM per ton. This standard works for most areas. Hot climates may use 500 CFM per ton.

How Many Tons in 400 CFM: Find Out Here
400 CFM equals one ton of cooling. For example:
- 400 CFM = 1 ton
- 800 CFM = 2 tons

HVAC CFM : Determine Your System’s Capacity
An HVAC system works efficiently when sized correctly. Use the calculator to find:
- Total CFM of the system.
- Divide by airflow per ton (400).
Calculate CFM per Ton: Essential for Accurate Cooling
Match airflow to cooling needs. For instance:
- Small spaces = 350 CFM per ton.
- Large halls = 400–450 CFM per ton.
