Convert Liters per Square Meter per Second to L/(dm²·min)

Formula

L/(dm²·min) = L/(m²·s) × 0.6

or L/(dm²·min) = L/(m²·s) ÷ 1.666666666667

Derivation from SI units:

• 1 L/(m²·s) = 10⁻³ m³ ÷ (1 m² × 1 s) = 10⁻³ m/s = 1 mm/s
• 1 L/(dm²·min) = 10⁻³ m³ ÷ (10⁻² m² × 60 s) = 1/600 m/s ≈ 1.667 mm/s
• 1 L/(m²·s) = 0.001 m/s ÷ 0.001666666666667 m/s per L/(dm²·min) = 0.6 L/(dm²·min)

Both units are defined exactly, so the factor is exact. Liter per Square Meter per Second definition: liter per square meter per second; Liter per Square Decimeter per Minute definition: liter per square decimeter per minute.

Worked examples

1. 100 L/(m²·s) is 60 L/(dm²·min).
   100 L/(m²·s) × 0.6 = 60 L/(dm²·min)
2. 1 L/(m²·s) is 0.6 L/(dm²·min).
   1 L/(m²·s) × 0.6 = 0.6 L/(dm²·min)

Where it's used

Modern L/(m²·s) values are converted to L/(dm²·min) when checking them against older specifications that still use that unit.
