Convert Decimeters per Second to Millimeters per Second
1 decimeter per second (dm/s) equals 100 millimeters per second (mm/s).
1 dm/s = 100 mm/s

How to Convert Decimeter per Second to Millimeter per Second
- 1 dm/s = 100 mm/s
- 1 mm/s = 0.01 dm/s
- Example: convert 15 dm/s to mm/s: 15 dm/s = 15 × 100 mm/s = 1500 mm/s
Formula
mm/s = dm/s × 100
Derivation from SI units:
- 1 dm/s = 0.1 m ÷ 1 s
- 1 mm/s = 0.001 m ÷ 1 s = 1 L/(m²·s)
- 1 dm/s = 0.1 m/s ÷ 0.001 m/s per mm/s = 100 mm/s
Both units are defined exactly, so the factor is exact. Decimeter per Second definition: decimeter per second; Millimeter per Second definition: millimeter per second.
Worked examples
- A reading of 2 dm/s converts to 200 mm/s.
2 dm/s × 100 = 200 mm/s - A value of 20 dm/s is 2000 mm/s.
20 dm/s × 100 = 2000 mm/s

Where it's used
Decimeters per Second are used for occasional instrument read-outs, while millimeters per second appear in air permeability of fabrics, nonwovens and papers (ISO 9237, EN ISO 9237). Both measure face velocity and air permeability (volumetric flow per unit area), so the conversion is a fixed factor.

Frequently asked questions
How many millimeters per second are in 1 decimeter per second?
1 dm/s = 100 mm/s.
How do I convert decimeters per second to millimeters per second?
Multiply the value in dm/s by 100. For example, 15 dm/s × 100 = 1500 mm/s.
Is the dm/s to mm/s conversion exact?
Yes. Both units are defined exactly, and 1 dm/s is exactly 100 mm/s.
