About Converting Cubic Millimeter per Seconds to Gallons per Fortnight
Cubic Millimeter per Seconds and Gallon per Fortnight both measure volumetric flow rate — how much volume passes a point over time — used to size pipes and pumps, monitor river or stream discharge, control industrial processes, and set medical infusion rates. Both are volumetric flow rate units.
Formula
gallons per fortnight = cubic millimeter per seconds × 0.319542514532
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic millimeter per seconds equals 1e-9 base units, and 1 gallon per fortnight equals 3.129474e-9 base units, so dividing one by the other gives the direct cubic millimeter per seconds-to-gallon per fortnight factor of 0.319542514532.
Simple example
1 mm3/s × 0.3195425145 = 0.3195425145 gal/fn
1 cubic millimeter per seconds = 0.3195425145 gallons per fortnight.
Real-world example
60 mm3/s × 0.3195425145 = 19.17255087 gal/fn
60 cubic millimeter per seconds = 19.17255087 gallons per fortnight.

Frequently asked questions
How many gallons per fortnight are in 1 cubic millimeter per seconds?
1 cubic millimeter per seconds equals 0.3195425145 gallons per fortnight, using the exact defined conversion factor rather than an estimate.
How do I convert cubic millimeter per seconds to gallon per fortnight?
Multiply the cubic millimeter per seconds value by 0.3195425145. The converter above does this instantly to whatever precision you set.
How do I convert gallon per fortnight back to cubic millimeter per seconds?
Use the reverse factor: 1 gallon per fortnight equals 3.129474028 cubic millimeter per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic millimeter per seconds?
Cubic Millimeter per Seconds (mm3/s) is a unit of flow rate.
What is a gallon per fortnight?
Gallon per Fortnight (gal/fn) is a unit of flow rate.
Is the cubic millimeter per seconds to gallon per fortnight conversion exact?
Yes. Both cubic millimeter per seconds and gallon per fortnight are defined by fixed standards rather than physical artifacts, so the factor of 0.3195425145 used above is exact to as many digits as you choose to display.
What's the difference between volumetric and mass flow rate?
Volumetric flow rate measures the volume of fluid passing a point per unit time (for example, liters per second). Mass flow rate measures the mass instead. For a fluid of constant density the two are directly proportional, but for compressible fluids like gases, mass flow is often the more meaningful quantity.
