Convert Cubic metres per hour to Millilitres per second
Convert Cubic metres per hour (m³/h) to Millilitres per second (mL/s) instantly and accurately.
Conversion Formula
mL/s = m³/h × 277.7777778
About Cubic metres per hour
The cubic metre per hour (m³/h) equals 1/3600 m³/s ≈ 2.778×10⁻⁴ m³/s, the dominant volumetric flow unit in European process engineering, HVAC, and water treatment. Pump datasheet curves, heat-exchanger sizing software, and wastewater-treatment design all use m³/h as the standard. A domestic water pump runs at 3-8 m³/h; a municipal WWTP inlet pump handles 500-5 000 m³/h. 1 m³/h ≈ 2.778×10⁻⁴ m³/s = 1 000 L/h.
About Millilitres per second
The millilitre per second (mL/s) equals 10⁻⁶ m³/s, common in laboratory syringe pumps, HPLC systems, and medical infusion devices. A standard IV drip running at 1 mL/s would deliver 3.6 L/h - a rapid infusion rate used in resuscitation; analytical HPLC columns run 0.5-5 mL/s. 1 mL/s = 10⁻⁶ m³/s = 60 mL/min = 3.6 L/h.
