About Converting Pint per Days to Imperial gallon per Years
Pint per Days and Imperial 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
imperial gallon per years = pint per days × 38.0160001099
This factor comes from each unit's defined relationship to the category's base unit: 1 pint per days equals 5.47658e-9 base units, and 1 imperial gallon per years equals 1.440599e-10 base units, so dividing one by the other gives the direct pint per days-to-imperial gallon per years factor of 38.0160001099.
Simple example
1 pt/d × 38.01600011 = 38.01600011 imp gal/yr
1 pint per days = 38.01600011 imperial gallon per years.
Real-world example
60 pt/d × 38.01600011 = 2,280.960007 imp gal/yr
60 pint per days = 2,280.960007 imperial gallon per years.

Frequently asked questions
How many imperial gallon per years are in 1 pint per days?
1 pint per days equals 38.01600011 imperial gallon per years, using the exact defined conversion factor rather than an estimate.

Multiply the pint per days value by 38.01600011. The converter above does this instantly to whatever precision you set.
How do I convert imperial gallon per years back to pint per days?
Use the reverse factor: 1 imperial gallon per years equals 0.0263047137 pint per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a pint per days?
Pint per Days (pt/d) is a unit of flow rate.
What is a imperial gallon per years?
Imperial gallon per Years (imp gal/yr) is a unit of flow rate.
Is the pint per days to imperial gallon per years conversion exact?
Yes. Both pint per days and imperial gallon per years are defined by fixed standards rather than physical artifacts, so the factor of 38.01600011 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.
