About Converting Teaspoon per Seconds to Gallons per Millisecond
Teaspoon per Seconds and Gallon 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. Both are volumetric flow rate units.
Formula
gallons per millisecond = teaspoon per seconds × 0.00000130208333333
This factor comes from each unit's defined relationship to the category's base unit: 1 teaspoon per seconds equals 0.00000492892159375 base units, and 1 gallon per millisecond equals 3.785411784 base units, so dividing one by the other gives the direct teaspoon per seconds-to-gallon per millisecond factor of 0.00000130208333333.
Simple example
1 tsp/s × 0.000001302083333 = 0.0000013021 gal/ms
1 teaspoon per seconds = 0.0000013021 gallons per millisecond.
Real-world example
60 tsp/s × 0.000001302083333 = 0.000078125 gal/ms
60 teaspoon per seconds = 0.000078125 gallons per millisecond.

Frequently asked questions
How many gallons per millisecond are in 1 teaspoon per seconds?
1 teaspoon per seconds equals 0.0000013021 gallons per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert teaspoon per seconds to gallon per millisecond?
Multiply the teaspoon per seconds value by 0.000001302083333. The converter above does this instantly to whatever precision you set.
How do I convert gallon per millisecond back to teaspoon per seconds?
Use the reverse factor: 1 gallon per millisecond equals 768,000 teaspoon per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a teaspoon per seconds?
Teaspoon per Seconds (tsp/s) is a unit of flow rate.
What is a gallon per millisecond?
Gallon per Millisecond (gal/ms) is a unit of flow rate.
Is the teaspoon per seconds to gallon per millisecond conversion exact?
Yes. Both teaspoon per seconds and gallon per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.000001302083333 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.
