How to Convert Millimeter per Second to Meter per Second
- 1 mm/s = 0.001 m/s
- 1 m/s = 1000 mm/s
- Example: convert 15 mm/s to m/s: 15 mm/s = 15 × 0.001 m/s = 0.015 m/s
Formula
m/s = mm/s ÷ 1000
Derivation from SI units:
- 1 mm/s = 0.001 m ÷ 1 s = 1 L/(m²·s)
- 1 m/s = 1 m ÷ 1 s (equivalently 1 m³/s of flow per 1 m² of area)
Both units are defined exactly, so the factor is exact. Millimeter per Second definition: millimeter per second; Meter per Second definition: meter per second.
Worked examples
- A reading of 100 mm/s converts to 0.1 m/s.
100 mm/s × 0.001 = 0.1 m/s - A value of 500 mm/s is 0.5 m/s.
500 mm/s × 0.001 = 0.5 m/s

Where it's used
Millimeters per Second are used for air permeability of fabrics, nonwovens and papers (ISO 9237, EN ISO 9237), while meters per second appear in filter face velocity (ISO 16890 full-size filters ≈ 2.7 m/s). Both measure face velocity and air permeability (volumetric flow per unit area), so the conversion is a fixed factor.

Frequently asked questions
How many meters per second are in 1 millimeter per second?
1 mm/s = 0.001 m/s.
How do I convert millimeters per second to meters per second?
Multiply the value in mm/s by 0.001, or divide it by 1000. For example, 15 mm/s × 0.001 = 0.015 m/s.
Is the mm/s to m/s conversion exact?
Yes. Both units are defined exactly, and 1 mm/s is exactly 0.001 m/s.
