About Converting Metric tablespoon per Days to Imperial gallon per Seconds
Metric 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 = metric tablespoon per days × 3.818911e-8
This factor comes from each unit's defined relationship to the category's base unit: 1 metric tablespoon per days equals 1.736111e-10 base units, and 1 imperial gallon per seconds equals 0.00454609 base units, so dividing one by the other gives the direct metric tablespoon per days-to-imperial gallon per seconds factor of 3.818911e-8.
Simple example
1 metric tbsp/d × 3.818911e-8 = 3.818911e-8 imp gal/s
1 metric tablespoon per days = 3.818911e-8 imperial gallon per seconds.
Real-world example
60 metric tbsp/d × 3.818911e-8 = 0.0000022913 imp gal/s
60 metric tablespoon per days = 0.0000022913 imperial gallon per seconds.

What is a metric tablespoon per days?
Metric tablespoon per Days (metric 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 metric tablespoon per days to imperial gallon per seconds conversion exact?
Yes. Both metric tablespoon per days and imperial gallon per seconds are defined by fixed standards rather than physical artifacts, so the factor of 3.818911e-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.
