How to Convert Bendtsen (mL/min) to Frazier (cfm/ft²)
- 1 mL/min (Bendtsen) = 0.0002789829843 cfm/ft² @125 Pa
- 1 cfm/ft² @125 Pa = 3584.448 mL/min (Bendtsen)
- Example: convert 15 mL/min (Bendtsen) to cfm/ft² @125 Pa: 15 mL/min (Bendtsen) = 15 × 0.0002789829843 cfm/ft² @125 Pa = 0.004184744764 cfm/ft² @125 Pa
Reference conditions. mL/min (Bendtsen): 10 cm² test area at 1.47 kPa (ISO 5636-3); assumes flow proportional to pressure difference. cfm/ft² @125 Pa: Measured at 125 Pa (0.5 inH₂O) as in ASTM D737; assumes flow proportional to pressure difference.
Formula
cfm/ft² @125 Pa = mL/min (Bendtsen) × 0.0002789829842698
or cfm/ft² @125 Pa = mL/min (Bendtsen) ÷ 3584.448
Derivation from SI units:
- Bendtsen reads mL/min through 10 cm² at 1.47 kPa: 1 mL/min ÷ (10 cm² × 1.47 kPa) = 0.011338 µm/(Pa·s).
- 1 cfm/ft² = 0.00508 m/s; at 125 Pa that is 0.00508 ÷ 125 = 4.064 × 10⁻⁵ m/(Pa·s) = 40.64 µm/(Pa·s).
- 1 mL/min (Bendtsen) = 0.01133786848073 µm/(Pa·s) ÷ 40.64 µm/(Pa·s) per cfm/ft² @125 Pa = 0.0002789829842698 cfm/ft² @125 Pa
One unit is a measured value, so the factor is approximate. Bendtsen (mL/min) definition: Bendtsen millilitre per minute; Frazier (cfm/ft²) definition: Frazier (cfm/ft² at 125 Pa).
Worked examples
- A reading of 200 mL/min (Bendtsen) converts to 0.05579659685 cfm/ft² @125 Pa.
200 mL/min (Bendtsen) × 0.0002789829843 = 0.05579659685 cfm/ft² @125 Pa - A value of 1500 mL/min (Bendtsen) is 0.4184744764 cfm/ft² @125 Pa.
1500 mL/min (Bendtsen) × 0.0002789829843 = 0.4184744764 cfm/ft² @125 Pa

Where it's used
Bendtsen (mL/min) are used for european paper mill quality control, while Frazier (cfm/ft² at 125 Pa) appear in woven and nonwoven filter media. Both measure air permeance (air flow per unit area per unit pressure difference), so the conversion is a fixed factor.

Frequently asked questions
How many Frazier (cfm/ft² at 125 Pa) are in 1 Bendtsen millilitre per minute?
1 mL/min (Bendtsen) = 0.0002789829843 cfm/ft² @125 Pa.
How do I convert Bendtsen millilitres per minute to Frazier (cfm/ft² at 125 Pa)?
Multiply the value in mL/min (Bendtsen) by 0.0002789829843, or divide it by 3584.448. For example, 15 mL/min (Bendtsen) × 0.0002789829843 = 0.004184744764 cfm/ft² @125 Pa.
Is the mL/min (Bendtsen) to cfm/ft² @125 Pa conversion exact?
Not exactly. The Bendtsen millilitre per minute is a measured value (10 cm² test area at 1.47 kPa (ISO 5636-3); assumes flow proportional to pressure difference.). The Frazier (cfm/ft² at 125 Pa) is a measured value (Measured at 125 Pa (0.5 inH₂O) as in ASTM D737; assumes flow proportional to pressure difference.). Results are good to about 5 significant figures.
