About Converting Tablespoon per Hours to Gallon per Hours
Tablespoon per Hours and Gallon per Hours 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 hours = tablespoon per hours × 0.00390625
This factor comes from each unit's defined relationship to the category's base unit: 1 tablespoon per hours equals 4.107435e-9 base units, and 1 gallon per hours equals 0.00000105150327333 base units, so dividing one by the other gives the direct tablespoon per hours-to-gallon per hours factor of 0.00390625.
Simple example
1 tbsp/h × 0.00390625 = 0.00390625 gal/h
1 tablespoon per hours = 0.00390625 gallon per hours.
Real-world example
60 tbsp/h × 0.00390625 = 0.234375 gal/h
60 tablespoon per hours = 0.234375 gallon per hours.

What is a tablespoon per hours?
Tablespoon per Hours (tbsp/h) is a unit of flow rate.
What is a gallon per hours?
Gallon per Hours (gal/h) is a unit of flow rate.
Is the tablespoon per hours to gallon per hours conversion exact?
Yes. Both tablespoon per hours and gallon per hours are defined by fixed standards rather than physical artifacts, so the factor of 0.00390625 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.
