cfm/ft² to l/s/m² and l/s/m² to cfm/ft² Calculator

How to Calculate Between cfm/ft² and l/s/m²

The cfm/ft² to l/s/m² and l/s/m² to cfm/ft² Calculator converts between cubic feet per minute per square foot (cfm/ft²) and liters per second per square meter (l/s/m²) for air velocity measurements. The formulas are:

\( l/s/m^2 = cfm/ft^2 \times 5.08 \)
\( cfm/ft^2 = \frac{l/s/m^2}{5.08} \)

Where:

\( cfm/ft^2 \): Cubic feet per minute per square foot, a unit of air velocity.
\( l/s/m^2 \): Liters per second per square meter, a unit of air velocity.

Select the conversion direction, enter the input value, and calculate the result.

Note: The conversion factor 5.08 is derived from 1 cfm = 0.47194745 l/s and 1 ft² = 0.092903 m².

Using the cfm/ft² and l/s/m² Mutual Conversion Calculator

This calculator is useful for HVAC design, ventilation rates, and air flow analysis, supporting bidirectional conversions between imperial and metric units.

Select the direction (cfm/ft² to l/s/m² or l/s/m² to cfm/ft²), input the value. The calculator outputs the converted value.

Example 1: For a value of 1 cfm/ft² to l/s/m².

Direction: cfm/ft² to l/s/m²
Input: \( 1 \)
Calculation: \( l/s/m^2 = 1 \times 5.08 = 5.08 \)
Result: \( 5.08 \, \text{l/s/m²} \)

Example 2: For a value of 10 l/s/m² to cfm/ft².

Direction: l/s/m² to cfm/ft²
Input: \( 10 \)
Calculation: \( cfm/ft^2 = 10 / 5.08 \approx 1.969 \)
Result: \( 1.969 \, \text{cfm/ft²} \)

Use this tool for quick bidirectional conversions in engineering or environmental applications.
