About Converting Teaspoon per Days to Pint per Years
Teaspoon 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 = teaspoon per days × 3.804609375
This factor comes from each unit's defined relationship to the category's base unit: 1 teaspoon per days equals 5.70477e-11 base units, and 1 pint per years equals 1.499437e-11 base units, so dividing one by the other gives the direct teaspoon per days-to-pint per years factor of 3.804609375.
Simple example
1 tsp/d × 3.804609375 = 3.804609375 pt/yr
1 teaspoon per days = 3.804609375 pint per years.
Real-world example
60 tsp/d × 3.804609375 = 228.2765625 pt/yr
60 teaspoon per days = 228.2765625 pint per years.

What is a teaspoon per days?
Teaspoon per Days (tsp/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 teaspoon per days to pint per years conversion exact?
Yes. Both teaspoon per days and pint per years are defined by fixed standards rather than physical artifacts, so the factor of 3.804609375 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.
