FPM to CFM Calculator

Formula

To calculate the Cubic Feet per Minute (CFM) from Feet per Minute (FPM):

$CFM = FPM \times A$

Where:

$CFM$ is the Cubic Feet per Minute
$FPM$ is the Feet per Minute
$A$ is the Area in square feet

What is the difference between FPM and CFM?

FPM stands for feet per minute and is a unit of measure that describes length per unit time. CFM stands for cubic feet per minute and is a unit of measure that describes volume per unit time. To convert between the two, the length in FPM must be multiplied by the area to get volume.

Example Calculation 1

Let's assume the following values:

Feet per Minute ( $FPM$ ) = 200 FPM
Area ( $A$ ) = 5 square feet

Using the formula:

$CFM = 200 \times 5 = 1000 \text{ CFM}$

The Cubic Feet per Minute is 1000 CFM.

Example Calculation 2

Let's assume the following values:

Feet per Minute ( $FPM$ ) = 150 FPM
Area ( $A$ ) = 10 square feet

Using the formula:

$CFM = 150 \times 10 = 1500 \text{ CFM}$

The Cubic Feet per Minute is 1500 CFM.
