How to Calculate Between cfm/ft² and l/s/cm²

The cfm/ft² to l/s/cm² and l/s/cm² to cfm/ft² Calculator converts between cubic feet per minute per square foot (cfm/ft²) and liters per second per square centimeter (l/s/cm²) for air velocity measurements. The formulas are:

Where:

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

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

Note: The conversion factor 0.000508 is derived from 1 cfm = 0.47194745 l/s and 1 ft² = 0.092903 m² (equivalent to 929.03 cm² since 1 m² = 10,000 cm²).

Using the cfm/ft² and l/s/cm² 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/cm² or l/s/cm² to cfm/ft²), input the value. The calculator outputs the converted value.

Example 1: For a value of 1000 cfm/ft² to l/s/cm².

1. Direction: cfm/ft² to l/s/cm²
2. Input: \( 1000 \)
3. Calculation: \( l/s/cm^2 = 1000 \times 0.000508 = 0.508 \)
4. Result: \( 0.508 \, \text{l/s/cm²} \)

Example 2: For a value of 0.508 l/s/cm² to cfm/ft².

1. Direction: l/s/cm² to cfm/ft²
2. Input: \( 0.508 \)
3. Calculation: \( cfm/ft^2 = 0.508 / 0.000508 \approx 1000 \)
4. Result: \( 1000 \, \text{cfm/ft²} \)

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