Convert Micrometres per Pascal Second to mm/s @200 Pa
1 micrometre per pascal second (µm/(Pa·s)) = 0.2 millimetres per second at 200 Pa (mm/s @200 Pa). 1 mm/s @200 Pa = 5 µm/(Pa·s). Example: 15 µm/(Pa·s) = 15 × 0.2 = 3 mm/s @200 Pa.

How to Convert Micrometre per Pascal Second to Millimetre per Second At 200 Pa
- 1 µm/(Pa·s) = 0.2 mm/s @200 Pa
- 1 mm/s @200 Pa = 5 µm/(Pa·s)
- Example: convert 15 µm/(Pa·s) to mm/s @200 Pa: 15 µm/(Pa·s) = 15 × 0.2 mm/s @200 Pa = 3 mm/s @200 Pa
Reference conditions. mm/s @200 Pa: Test pressure 200 Pa (ISO 9237 industrial fabrics, EN filter media); assumes flow proportional to pressure difference.
Formula
mm/s @200 Pa = µm/(Pa·s) ÷ 5
Derivation from SI units:
- Air permeance P = flow per unit area per unit pressure difference = 10⁻⁶ m/(Pa·s) (ISO 5636-1).
- 1 mm/s ÷ 200 Pa = 5 × 10⁻⁶ m/(Pa·s) = 5 µm/(Pa·s).
One unit is a measured value, so the factor is approximate. Micrometre per Pascal Second definition: micrometre per pascal second; Millimetre per Second At 200 Pa definition: millimetre per second at 200 Pa.
Worked examples
- A reading of 1 µm/(Pa·s) converts to 0.2 mm/s @200 Pa.
1 µm/(Pa·s) × 0.2 = 0.2 mm/s @200 Pa - A value of 10 µm/(Pa·s) is 2 mm/s @200 Pa.
10 µm/(Pa·s) × 0.2 = 2 mm/s @200 Pa

Where it's used
Micrometres per Pascal Second are used for paper and board air permeance (ISO 5636), while millimetres per second at 200 Pa appear in industrial and filter fabrics. 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 millimetres per second at 200 Pa are in 1 micrometre per pascal second?
1 µm/(Pa·s) = 0.2 mm/s @200 Pa.
How do I convert micrometres per pascal second to millimetres per second at 200 Pa?
Multiply the value in µm/(Pa·s) by 0.2, or divide it by 5. For example, 15 µm/(Pa·s) × 0.2 = 3 mm/s @200 Pa.
Is the µm/(Pa·s) to mm/s @200 Pa conversion exact?
Not exactly. The millimetre per second at 200 Pa is a measured value (Test pressure 200 Pa (ISO 9237 industrial fabrics, EN filter media); assumes flow proportional to pressure difference.). Results are good to about 5 significant figures.
