About Converting Gallon per Minutes to Tablespoons per Millisecond
Gallon per Minutes and Tablespoon per Millisecond 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. Gallon per Minutes is most often used for us residential and commercial plumbing fixture flow ratings.
Formula
tablespoons per millisecond = gallon per minutes × 0.00426666666667
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per minutes equals 0.0000630901964 base units, and 1 tablespoon per millisecond equals 0.0147867647812 base units, so dividing one by the other gives the direct gallon per minutes-to-tablespoon per millisecond factor of 0.00426666666667.
Simple example
1 gal/min × 0.004266666667 = 0.0042666667 tbsp/ms
1 gallon per minutes = 0.0042666667 tablespoons per millisecond.
Real-world example
60 gal/min × 0.004266666667 = 0.256 tbsp/ms
60 gallon per minutes = 0.256 tablespoons per millisecond.

Frequently asked questions
How many tablespoons per millisecond are in 1 gallon per minutes?
1 gallon per minutes equals 0.0042666667 tablespoons per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per minutes to tablespoon per millisecond?
Multiply the gallon per minutes value by 0.004266666667. The converter above does this instantly to whatever precision you set.
How do I convert tablespoon per millisecond back to gallon per minutes?
Use the reverse factor: 1 tablespoon per millisecond equals 234.375 gallon per minutes. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per minutes?
Gallon per Minutes (gal/min) measures volumetric flow rate. The standard US unit for pump, plumbing, and irrigation flow-rate specifications. It is classified as a US customary flow-rate unit.
What is a tablespoon per millisecond?
Tablespoon per Millisecond (tbsp/ms) is a unit of flow rate.
Is the gallon per minutes to tablespoon per millisecond conversion exact?
Yes. Both gallon per minutes and tablespoon per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.004266666667 used above is exact to as many digits as you choose to display.
Where is the gallon per minutes still used today?
United States (plumbing, pump, and irrigation industry standard)
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.
