How to Convert Millimetre per Second At 100 Pa to Frazier (cfm/ft²)
- 1 mm/s @100 Pa = 0.2460629921 cfm/ft² @125 Pa
- 1 cfm/ft² @125 Pa = 4.064 mm/s @100 Pa
- Example: convert 15 mm/s @100 Pa to cfm/ft² @125 Pa: 15 mm/s @100 Pa = 15 × 0.2460629921 cfm/ft² @125 Pa = 3.690944882 cfm/ft² @125 Pa
Reference conditions. mm/s @100 Pa: Test pressure 100 Pa (ISO 9237 apparel fabrics); 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 = mm/s @100 Pa × 0.246062992126
or cfm/ft² @125 Pa = mm/s @100 Pa ÷ 4.064
Derivation from SI units:
- 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 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 mm/s @100 Pa = 10 µm/(Pa·s) ÷ 40.64 µm/(Pa·s) per cfm/ft² @125 Pa = 0.246062992126 cfm/ft² @125 Pa
One unit is a measured value, so the factor is approximate. Millimetre per Second At 100 Pa definition: millimetre per second at 100 Pa; Frazier (cfm/ft²) definition: Frazier (cfm/ft² at 125 Pa).
Worked examples
- A reading of 20 mm/s @100 Pa converts to 4.921259843 cfm/ft² @125 Pa.
20 mm/s @100 Pa × 0.2460629921 = 4.921259843 cfm/ft² @125 Pa - A value of 200 mm/s @100 Pa is 49.21259843 cfm/ft² @125 Pa.
200 mm/s @100 Pa × 0.2460629921 = 49.21259843 cfm/ft² @125 Pa

Where it's used
Millimetres per Second At 100 Pa are used for apparel and shirting fabrics (ISO 9237), 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 millimetre per second at 100 Pa?
1 mm/s @100 Pa = 0.2460629921 cfm/ft² @125 Pa.
How do I convert millimetres per second at 100 Pa to Frazier (cfm/ft² at 125 Pa)?
Multiply the value in mm/s @100 Pa by 0.2460629921, or divide it by 4.064. For example, 15 mm/s @100 Pa × 0.2460629921 = 3.690944882 cfm/ft² @125 Pa.
Is the mm/s @100 Pa to cfm/ft² @125 Pa conversion exact?
Not exactly. 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.). 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.
