Enter the total volume (ft^3) into the Calculator. The calculator will evaluate the Dehumidifier Capacity. 

Dehumidifier Capacity Formula

DHC = V / 60 * 3


  • DHC is the Dehumidifier Capacity (SCFM)
  • V is the total volume (ft^3)

To calculate Dehumidifier Capacity, divide the total volume by 60, then multiply by 3.

How to Calculate Dehumidifier Capacity?

The following steps outline how to calculate the Dehumidifier Capacity.

  1. First, determine the total volume (ft^3). 
  2. Next, gather the formula from above = DHC = V / 60 * 3.
  3. Finally, calculate the Dehumidifier Capacity.
  4. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

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

total volume (ft^3) = 300,000
