About Converting Tablespoon per Days to Gallon per Years
Tablespoon per Days 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 = tablespoon per days × 1.42672851563
This factor comes from each unit's defined relationship to the category's base unit: 1 tablespoon per days equals 1.711431e-10 base units, and 1 gallon per years equals 1.199549e-10 base units, so dividing one by the other gives the direct tablespoon per days-to-gallon per years factor of 1.42672851563.
Simple example
1 tbsp/d × 1.426728516 = 1.426728516 gal/yr
1 tablespoon per days = 1.426728516 gallon per years.
Real-world example
60 tbsp/d × 1.426728516 = 85.60371094 gal/yr
60 tablespoon per days = 85.60371094 gallon per years.

What is a tablespoon per days?
Tablespoon per Days (tbsp/d) 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 tablespoon per days to gallon per years conversion exact?
Yes. Both tablespoon per days and gallon per years are defined by fixed standards rather than physical artifacts, so the factor of 1.426728516 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.
