About Converting Imperial gallon per Days to Pint per Years
Imperial gallon per Days and Pint 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
pint per years = imperial gallon per days × 3509.10362533
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial gallon per days equals 5.261678e-8 base units, and 1 pint per years equals 1.499437e-11 base units, so dividing one by the other gives the direct imperial gallon per days-to-pint per years factor of 3509.10362533.
Simple example
1 imp gal/d × 3509.103625 = 3,509.103625 pt/yr
1 imperial gallon per days = 3,509.103625 pint per years.
Real-world example
60 imp gal/d × 3509.103625 = 210,546.2175 pt/yr
60 imperial gallon per days = 210,546.2175 pint per years.

Frequently asked questions
How many pint per years are in 1 imperial gallon per days?
1 imperial gallon per days equals 3,509.103625 pint per years, using the exact defined conversion factor rather than an estimate.

Multiply the imperial gallon per days value by 3509.103625. The converter above does this instantly to whatever precision you set.
How do I convert pint per years back to imperial gallon per days?
Use the reverse factor: 1 pint per years equals 0.0002849731 imperial gallon per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial gallon per days?
Imperial gallon per Days (imp gal/d) is a unit of flow rate.
What is a pint per years?
Pint per Years (pt/yr) is a unit of flow rate.
Is the imperial gallon per days to pint per years conversion exact?
Yes. Both imperial gallon per days and pint per years are defined by fixed standards rather than physical artifacts, so the factor of 3509.103625 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.
