Convert Millilitres per hour to Microlitres per second
Convert Millilitres per hour (mL/h) to Microlitres per second (µL/s) instantly and accurately.
Conversion Formula
µL/s = mL/h × 0.2777777778
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 Microlitres per second
The microlitre per second (µL/s) equals 10⁻⁹ m³/s, the working range of microfluidic lab-on-a-chip devices and nano-HPLC pumps. Organ-on-a-chip perfusion bioreactors, droplet microfluidic systems, and capillary electrophoresis instruments operate at 0.1-100 µL/s. A syringe pump delivering 0.36 mL/h produces exactly 0.1 µL/s. 1 µL/s = 10⁻⁹ m³/s = 60 µL/min.
