About Converting Gallon per Seconds to Teaspoon per Days
Gallon per Seconds and Teaspoon per Days 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
teaspoon per days = gallon per seconds × 66355200
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per seconds equals 0.003785411784 base units, and 1 teaspoon per days equals 5.70477e-11 base units, so dividing one by the other gives the direct gallon per seconds-to-teaspoon per days factor of 66355200.
Simple example
1 gal/s × 66355200 = 66,355,200 tsp/d
1 gallon per seconds = 66,355,200 teaspoon per days.
Real-world example
60 gal/s × 66355200 = 3,981,312,000 tsp/d
60 gallon per seconds = 3,981,312,000 teaspoon per days.

Frequently asked questions
How many teaspoon per days are in 1 gallon per seconds?
1 gallon per seconds equals 66,355,200 teaspoon per days, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per seconds to teaspoon per days?
Multiply the gallon per seconds value by 66355200. The converter above does this instantly to whatever precision you set.
How do I convert teaspoon per days back to gallon per seconds?
Use the reverse factor: 1 teaspoon per days equals 1.507041e-8 gallon per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per seconds?
Gallon per Seconds (gal/s) is a unit of flow rate.
What is a teaspoon per days?
Teaspoon per Days (tsp/d) is a unit of flow rate.
Is the gallon per seconds to teaspoon per days conversion exact?
Yes. Both gallon per seconds and teaspoon per days are defined by fixed standards rather than physical artifacts, so the factor of 66355200 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.
