About Converting Cubic foot per Days to Pint per Years
Cubic foot 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 = cubic foot per days × 21857.6290909
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic foot per days equals 3.277413e-7 base units, and 1 pint per years equals 1.499437e-11 base units, so dividing one by the other gives the direct cubic foot per days-to-pint per years factor of 21857.6290909.
Simple example
1 ft3/d × 21857.62909 = 21,857.62909 pt/yr
1 cubic foot per days = 21,857.62909 pint per years.
Real-world example
60 ft3/d × 21857.62909 = 1,311,457.745 pt/yr
60 cubic foot per days = 1,311,457.745 pint per years.

Multiply the cubic foot per days value by 21857.62909. The converter above does this instantly to whatever precision you set.
How do I convert pint per years back to cubic foot per days?
Use the reverse factor: 1 pint per years equals 0.0000457506 cubic foot per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic foot per days?
Cubic foot per Days (ft3/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 cubic foot per days to pint per years conversion exact?
Yes. Both cubic foot per days and pint per years are defined by fixed standards rather than physical artifacts, so the factor of 21857.62909 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.
