How to Convert Frazier (cfm/ft²) to Millimetre per Second At 100 Pa
- 1 cfm/ft² @125 Pa = 4.064 mm/s @100 Pa
- 1 mm/s @100 Pa = 0.2460629921 cfm/ft² @125 Pa
- Example: convert 15 cfm/ft² @125 Pa to mm/s @100 Pa: 15 cfm/ft² @125 Pa = 15 × 4.064 mm/s @100 Pa = 60.96 mm/s @100 Pa
Reference conditions. cfm/ft² @125 Pa: Measured at 125 Pa (0.5 inH₂O) as in ASTM D737; 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 = cfm/ft² @125 Pa × 4.064
Derivation from SI units:
- 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 = 10⁻⁵ m/(Pa·s) = 10 µm/(Pa·s); the same number as L/(m²·s) at 100 Pa.
- 1 cfm/ft² @125 Pa = 40.64 µm/(Pa·s) ÷ 10 µm/(Pa·s) per mm/s @100 Pa = 4.064 mm/s @100 Pa
One unit is a measured value, so the factor is approximate. Frazier (cfm/ft²) definition: Frazier (cfm/ft² at 125 Pa); Millimetre per Second At 100 Pa definition: millimetre per second at 100 Pa.
Worked examples
- A reading of 5 cfm/ft² @125 Pa converts to 20.32 mm/s @100 Pa.
5 cfm/ft² @125 Pa × 4.064 = 20.32 mm/s @100 Pa - A value of 50 cfm/ft² @125 Pa is 203.2 mm/s @100 Pa.
50 cfm/ft² @125 Pa × 4.064 = 203.2 mm/s @100 Pa

Where it's used
Frazier (cfm/ft²) are used for woven and nonwoven filter media, 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.
Frazier (cfm/ft²) to other air permeance units
| Conversion | 1 cfm/ft² @125 Pa equals |

| Frazier to millimetre per second at 100 Pa | 4.064 mm/s @100 Pa |
| Frazier to micrometre per pascal second | 40.64 µm/(Pa·s) |
| Frazier to Gurley second | 3.126991894 s/100 mL |
| Frazier to Bendtsen | 3584.448 mL/min (Bendtsen) |
| Frazier to millimetre per second at 200 Pa | 8.128 mm/s @200 Pa |
Frequently asked questions
How many millimetres per second at 100 Pa are in 1 Frazier (cfm/ft² at 125 Pa)?
1 cfm/ft² @125 Pa = 4.064 mm/s @100 Pa.
How do I convert Frazier (cfm/ft² at 125 Pa) to millimetres per second at 100 Pa?
Multiply the value in cfm/ft² @125 Pa by 4.064. For example, 15 cfm/ft² @125 Pa × 4.064 = 60.96 mm/s @100 Pa.
Is the cfm/ft² @125 Pa to mm/s @100 Pa conversion exact?
Not exactly. 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.). 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.
