Quick Reference

1 Litre per hour (l/h) = 277.7777778 Cubic Millimeter per second (mm3/s)

1 Cubic Millimeter per second (mm3/s) = 0.0036 Litre per hour (l/h)

How to Convert Litre per hour to Cubic Millimeter per second

1 l/h = 277.7777778 mm3/s
1 mm3/s = 0.0036 l/h

To convert Litre per hour to Cubic Millimeter per second, multiply the value by 277.7777778. To convert Cubic Millimeter per second back to Litre per hour, divide by 277.7777778.

Example: convert 10 l/h to mm3/s:
10 l/h = 10 x 277.7777778 = 2777.777778 mm3/s

↔ Convert Cubic Millimeter per second to Litre per hour

Litre per hour

Definition: Liters per hour (L/h) is a unit of volumetric flow rate. It represents the volume of a substance passing through a given point per unit of time, measured in liters per hour.

History/origin: The liter (L) is a metric unit of volume. Using 'per hour' provides a convenient timescale for processes that involve slower flow rates.

Current use: L/h is used for measuring very slow flow rates, such as in drip irrigation systems, chemical dosing, or water purification processes.

Cubic Millimeter per second

Definition: Cubic millimeters per second (mm³/s) is a unit of volumetric flow rate, representing the volume of a substance passing through a given point per unit of time. Specifically, it measures the volume in cubic millimeters that flows past a point in one second.

History/origin: This unit is derived from the fundamental SI units of length (meter) and time (second). The cubic millimeter is a derived unit of volume, and combining it with the 'per second' time component creates a flow rate unit.

Current use: mm³/s is used in applications where very small flow rates are relevant, such as microfluidics, precision dispensing systems, or in certain scientific instruments.
