Conversion Formula

L/s = mL/h × 2.777777778e-7

About Millilitres per hour

The millilitre per hour (mL/h) equals 10⁻⁶/3600 ≈ 2.778×10⁻¹⁰ m³/s, standard for intravenous infusion pumps in clinical medicine and for slow-release laboratory syringe pumps. A 1 L IV bag running over 8 hours is set to 125 mL/h; subcutaneous insulin pumps deliver 1-100 mL/h of dilute insulin. 1 mL/h ≈ 2.778×10⁻¹⁰ m³/s.

About Litres per second

The litre per second (L/s) equals 10⁻³ m³/s, the standard unit for municipal water-supply engineering, fire-fighting flows, and HVAC system air handling. A fire hydrant delivers 15-30 L/s; a household mains water connection is typically 0.1-0.5 L/s; a large building HVAC chilled-water loop circulates 50-200 L/s. 1 L/s = 10⁻³ m³/s = 3.6 m³/h ≈ 15.85 US gal/min.
