Convert Liters per Square Meter per Second to mm/s
1 liter per square meter per second (L/(m²·s)) equals 1 millimeter per second (mm/s).
1 L/(m²·s) = 1 mm/s

How to Convert Liter per Square Meter per Second to Millimeter per Second
- 1 L/(m²·s) = 1 mm/s
- 1 mm/s = 1 L/(m²·s)
- Example: convert 15 L/(m²·s) to mm/s: 15 L/(m²·s) = 15 × 1 mm/s = 15 mm/s
Formula
mm/s = L/(m²·s) × 1
Derivation from SI units:
- 1 L/(m²·s) = 10⁻³ m³ ÷ (1 m² × 1 s) = 10⁻³ m/s = 1 mm/s
- 1 mm/s = 0.001 m ÷ 1 s = 1 L/(m²·s)
- 1 L/(m²·s) = 0.001 m/s ÷ 0.001 m/s per mm/s = 1 mm/s
Both units are defined exactly, so the factor is exact. Liter per Square Meter per Second definition: liter per square meter per second; Millimeter per Second definition: millimeter per second.
Worked examples
- 500 L/(m²·s) is 500 mm/s.
500 L/(m²·s) × 1 = 500 mm/s - A tightly woven fabric at 75 L/(m²·s) is 75 mm/s.
75 L/(m²·s) × 1 = 75 mm/s

Frequently asked questions
Are L/(m²·s) and mm/s interchangeable?
Yes. The conversion factor is exactly 1.
How many millimeters per second are in 1 liter per square meter per second?
1 L/(m²·s) = 1 mm/s.
How do I convert liters per square meter per second to millimeters per second?
Multiply the value in L/(m²·s) by 1. For example, 15 L/(m²·s) × 1 = 15 mm/s.
Is the L/(m²·s) to mm/s conversion exact?
Yes. Both units are defined exactly, and 1 L/(m²·s) is exactly 1 mm/s.
