About Converting Gallon per Minutes to Pints per Fortnight
Gallon per Minutes and Pint 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. Gallon per Minutes is most often used for us residential and commercial plumbing fixture flow ratings.
Formula
pints per fortnight = gallon per minutes × 161280
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per minutes equals 0.0000630901964 base units, and 1 pint per fortnight equals 3.911843e-10 base units, so dividing one by the other gives the direct gallon per minutes-to-pint per fortnight factor of 161280.
Simple example
1 gal/min × 161280 = 161,280 pt/fn
1 gallon per minutes = 161,280 pints per fortnight.
Real-world example
60 gal/min × 161280 = 9,676,800 pt/fn
60 gallon per minutes = 9,676,800 pints per fortnight.

Frequently asked questions
How many pints per fortnight are in 1 gallon per minutes?
1 gallon per minutes equals 161,280 pints per fortnight, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per minutes to pint per fortnight?
Multiply the gallon per minutes value by 161280. The converter above does this instantly to whatever precision you set.
How do I convert pint per fortnight back to gallon per minutes?
Use the reverse factor: 1 pint per fortnight equals 0.0000062004 gallon per minutes. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per minutes?
Gallon per Minutes (gal/min) measures volumetric flow rate. The standard US unit for pump, plumbing, and irrigation flow-rate specifications. It is classified as a US customary flow-rate unit.
What is a pint per fortnight?
Pint per Fortnight (pt/fn) is a unit of flow rate.
Is the gallon per minutes to pint per fortnight conversion exact?
Yes. Both gallon per minutes and pint per fortnight are defined by fixed standards rather than physical artifacts, so the factor of 161280 used above is exact to as many digits as you choose to display.
Where is the gallon per minutes still used today?
United States (plumbing, pump, and irrigation industry standard)
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.
