About Converting Pint per Years to Gallon per Years
Pint per Years and Gallon per Years 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
gallon per years = pint per years × 0.125
This factor comes from each unit's defined relationship to the category's base unit: 1 pint per years equals 1.499437e-11 base units, and 1 gallon per years equals 1.199549e-10 base units, so dividing one by the other gives the direct pint per years-to-gallon per years factor of 0.125.
Simple example
1 pt/yr × 0.125 = 0.125 gal/yr
1 pint per years = 0.125 gallon per years.
Real-world example
60 pt/yr × 0.125 = 7.5 gal/yr
60 pint per years = 7.5 gallon per years.

Frequently asked questions
How many gallon per years are in 1 pint per years?
1 pint per years equals 0.125 gallon per years, using the exact defined conversion factor rather than an estimate.
How do I convert pint per years to gallon per years?
Multiply the pint per years value by 0.125. The converter above does this instantly to whatever precision you set.
How do I convert gallon per years back to pint per years?
Use the reverse factor: 1 gallon per years equals 8 pint per years. You can also use the swap control in the converter above to flip the direction instantly.
What is a pint per years?
Pint per Years (pt/yr) is a unit of flow rate.
What is a gallon per years?
Gallon per Years (gal/yr) is a unit of flow rate.
Is the pint per years to gallon per years conversion exact?
Yes. Both pint per years and gallon per years are defined by fixed standards rather than physical artifacts, so the factor of 0.125 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.
