Gallon per hour [gal/h] to Cubic Millimeter per second [mm3/s] Converter

Quick Reference

1 Gallon per hour (gal/h) = 1051.503273 Cubic Millimeter per second (mm3/s)

1 Cubic Millimeter per second (mm3/s) = 0.0009510193884 Gallon per hour (gal/h)

How to Convert Gallon per hour to Cubic Millimeter per second

1 gal/h = 1051.503273 mm3/s
1 mm3/s = 0.0009510193884 gal/h

To convert Gallon per hour to Cubic Millimeter per second, multiply the value by 1051.503273. To convert Cubic Millimeter per second back to Gallon per hour, divide by 1051.503273.

Example: convert 10 gal/h to mm3/s:
10 gal/h = 10 x 1051.503273 = 10515.03273 mm3/s

↔ Convert Cubic Millimeter per second to Gallon per hour

Gallon per hour

Definition: Gallons per hour (gal/h) is a flow rate unit that expresses how many gallons of fluid pass a point in one hour. It is suitable for measuring slow flow rates over extended durations.

History/origin: The unit is built upon the standard gallon unit of volume combined with a 'per hour' timeframe, useful for situations where flow rates are relatively slow.

Current use: Applications include measuring fuel consumption rates in vehicles, low-flow chemical dosing, and the monitoring of slow leaks in fluid systems.

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.
