About Converting Tablespoon per Days to Imperial gallon per Years
Tablespoon 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 = tablespoon per days × 1.18800000343
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 imperial gallon per years equals 1.440599e-10 base units, so dividing one by the other gives the direct tablespoon per days-to-imperial gallon per years factor of 1.18800000343.
Simple example
1 tbsp/d × 1.188000003 = 1.188000003 imp gal/yr
1 tablespoon per days = 1.188000003 imperial gallon per years.
Real-world example
60 tbsp/d × 1.188000003 = 71.28000021 imp gal/yr
60 tablespoon per days = 71.28000021 imperial gallon per years.

What is a tablespoon per days?
Tablespoon per Days (tbsp/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 tablespoon per days to imperial gallon per years conversion exact?
Yes. Both tablespoon per days and imperial gallon per years are defined by fixed standards rather than physical artifacts, so the factor of 1.188000003 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.
