About Converting Tablespoon per Days to Imperial gallon per Seconds
Tablespoon per Days and Imperial gallon per Seconds 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 seconds = tablespoon per days × 3.764622e-8
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 seconds equals 0.00454609 base units, so dividing one by the other gives the direct tablespoon per days-to-imperial gallon per seconds factor of 3.764622e-8.
Simple example
1 tbsp/d × 3.764622e-8 = 3.764622e-8 imp gal/s
1 tablespoon per days = 3.764622e-8 imperial gallon per seconds.
Real-world example
60 tbsp/d × 3.764622e-8 = 0.0000022588 imp gal/s
60 tablespoon per days = 0.0000022588 imperial gallon per seconds.

What is a tablespoon per days?
Tablespoon per Days (tbsp/d) is a unit of flow rate.
What is a imperial gallon per seconds?
Imperial gallon per Seconds (imp gal/s) is a unit of flow rate.
Is the tablespoon per days to imperial gallon per seconds conversion exact?
Yes. Both tablespoon per days and imperial gallon per seconds are defined by fixed standards rather than physical artifacts, so the factor of 3.764622e-8 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.
