Convert Millimetres per Second At 200 Pa to mm/s @100 Pa
1 millimetre per second at 200 Pa (mm/s @200 Pa) = 0.5 millimetres per second at 100 Pa (mm/s @100 Pa). 1 mm/s @100 Pa = 2 mm/s @200 Pa. Example: 15 mm/s @200 Pa = 15 × 0.5 = 7.5 mm/s @100 Pa.

How to Convert Millimetre per Second At 200 Pa to Millimetre per Second At 100 Pa
- 1 mm/s @200 Pa = 0.5 mm/s @100 Pa
- 1 mm/s @100 Pa = 2 mm/s @200 Pa
- Example: convert 15 mm/s @200 Pa to mm/s @100 Pa: 15 mm/s @200 Pa = 15 × 0.5 mm/s @100 Pa = 7.5 mm/s @100 Pa
Reference conditions. mm/s @200 Pa: Test pressure 200 Pa (ISO 9237 industrial fabrics, EN filter media); assumes flow proportional to pressure difference. mm/s @100 Pa: Test pressure 100 Pa (ISO 9237 apparel fabrics); assumes flow proportional to pressure difference.
Formula
mm/s @100 Pa = mm/s @200 Pa ÷ 2
Derivation from SI units:
- 1 mm/s ÷ 200 Pa = 5 × 10⁻⁶ m/(Pa·s) = 5 µm/(Pa·s).
- 1 mm/s ÷ 100 Pa = 10⁻⁵ m/(Pa·s) = 10 µm/(Pa·s); the same number as L/(m²·s) at 100 Pa.
- 1 mm/s @200 Pa = 5 µm/(Pa·s) ÷ 10 µm/(Pa·s) per mm/s @100 Pa = 0.5 mm/s @100 Pa
One unit is a measured value, so the factor is approximate. Millimetre per Second At 200 Pa definition: millimetre per second at 200 Pa; Millimetre per Second At 100 Pa definition: millimetre per second at 100 Pa.
Worked examples
- A reading of 100 mm/s @200 Pa converts to 50 mm/s @100 Pa.
100 mm/s @200 Pa × 0.5 = 50 mm/s @100 Pa - A value of 1000 mm/s @200 Pa is 500 mm/s @100 Pa.
1000 mm/s @200 Pa × 0.5 = 500 mm/s @100 Pa

Where it's used
Millimetres per Second At 200 Pa are used for industrial and filter fabrics, while millimetres per second at 100 Pa appear in apparel and shirting fabrics (ISO 9237). Both measure air permeance (air flow per unit area per unit pressure difference), so the conversion is a fixed factor.
Millimetre per Second At 200 Pa to other air permeance units

Frequently asked questions
How many millimetres per second at 100 Pa are in 1 millimetre per second at 200 Pa?
1 mm/s @200 Pa = 0.5 mm/s @100 Pa.
How do I convert millimetres per second at 200 Pa to millimetres per second at 100 Pa?
Multiply the value in mm/s @200 Pa by 0.5, or divide it by 2. For example, 15 mm/s @200 Pa × 0.5 = 7.5 mm/s @100 Pa.
Is the mm/s @200 Pa to mm/s @100 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.). The millimetre per second at 100 Pa is a measured value (Test pressure 100 Pa (ISO 9237 apparel fabrics); assumes flow proportional to pressure difference.). Results are good to about 5 significant figures.
