About Converting Teaspoon per Days to Gallon per Minutes
Teaspoon per Days and Gallon per Minutes 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 minutes = teaspoon per days × 9.042245e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 teaspoon per days equals 5.70477e-11 base units, and 1 gallon per minutes equals 0.0000630901964 base units, so dividing one by the other gives the direct teaspoon per days-to-gallon per minutes factor of 9.042245e-7.
Simple example
1 tsp/d × 9.042245e-7 = 9.042245e-7 gal/min
1 teaspoon per days = 9.042245e-7 gallon per minutes.
Real-world example
60 tsp/d × 9.042245e-7 = 0.0000542535 gal/min
60 teaspoon per days = 0.0000542535 gallon per minutes.

Frequently asked questions
How many gallon per minutes are in 1 teaspoon per days?
1 teaspoon per days equals 9.042245e-7 gallon per minutes, using the exact defined conversion factor rather than an estimate.
How do I convert teaspoon per days to gallon per minutes?
Multiply the teaspoon per days value by 9.042245e-7. The converter above does this instantly to whatever precision you set.
How do I convert gallon per minutes back to teaspoon per days?
Use the reverse factor: 1 gallon per minutes equals 1,105,920 teaspoon per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a teaspoon per days?
Teaspoon per Days (tsp/d) is a unit of flow rate.
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.
Is the teaspoon per days to gallon per minutes conversion exact?
Yes. Both teaspoon per days and gallon per minutes are defined by fixed standards rather than physical artifacts, so the factor of 9.042245e-7 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.
