About Litres per hour

The litre per hour (L/h) equals 10⁻³/3600 ≈ 2.778×10⁻⁷ m³/s, widely used in automotive fuel consumption (L/h), irrigation drip systems, and small pump specifications. A fuel cell vehicle running on hydrogen consumes ±2 L/h of liquid equivalent; a domestic water softener regeneration cycle uses 40-100 L/h of brine. 1 L/h ≈ 2.778×10⁻⁷ m³/s ≈ 0.2642 US gal/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.
