How to Convert Micrometre per Pascal Second to Bendtsen (mL/min)
- 1 µm/(Pa·s) = 88.2 mL/min (Bendtsen)
- 1 mL/min (Bendtsen) = 0.01133786848 µm/(Pa·s)
- Example: convert 15 µm/(Pa·s) to mL/min (Bendtsen): 15 µm/(Pa·s) = 15 × 88.2 mL/min (Bendtsen) = 1323 mL/min (Bendtsen)
Reference conditions. mL/min (Bendtsen): 10 cm² test area at 1.47 kPa (ISO 5636-3); assumes flow proportional to pressure difference.
Formula
mL/min (Bendtsen) = µm/(Pa·s) × 88.2
Derivation from SI units:
- Air permeance P = flow per unit area per unit pressure difference = 10⁻⁶ m/(Pa·s) (ISO 5636-1).
- Bendtsen reads mL/min through 10 cm² at 1.47 kPa: 1 mL/min ÷ (10 cm² × 1.47 kPa) = 0.011338 µm/(Pa·s).
One unit is a measured value, so the factor is approximate. Micrometre per Pascal Second definition: micrometre per pascal second; Bendtsen (mL/min) definition: Bendtsen millilitre per minute.
Worked examples
- A reading of 1 µm/(Pa·s) converts to 88.2 mL/min (Bendtsen).
1 µm/(Pa·s) × 88.2 = 88.2 mL/min (Bendtsen) - A value of 10 µm/(Pa·s) is 882 mL/min (Bendtsen).
10 µm/(Pa·s) × 88.2 = 882 mL/min (Bendtsen)

Where it's used
Micrometres per Pascal Second are used for paper and board air permeance (ISO 5636), while Bendtsen millilitres per minute appear in european paper mill quality control. 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 Bendtsen millilitres per minute are in 1 micrometre per pascal second?
1 µm/(Pa·s) = 88.2 mL/min (Bendtsen).
How do I convert micrometres per pascal second to Bendtsen millilitres per minute?
Multiply the value in µm/(Pa·s) by 88.2. For example, 15 µm/(Pa·s) × 88.2 = 1323 mL/min (Bendtsen).
Is the µm/(Pa·s) to mL/min (Bendtsen) 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.). Results are good to about 5 significant figures.
