About Converting Teaspoons per Millisecond to Gallon per Hours
Teaspoon per Millisecond and Gallon per Hours 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 hours = teaspoons per millisecond × 4687.5
This factor comes from each unit's defined relationship to the category's base unit: 1 teaspoon per millisecond equals 0.00492892159375 base units, and 1 gallon per hours equals 0.00000105150327333 base units, so dividing one by the other gives the direct teaspoon per millisecond-to-gallon per hours factor of 4687.5.
Simple example
1 tsp/ms × 4687.5 = 4,687.5 gal/h
1 teaspoon per millisecond = 4,687.5 gallon per hours.
Real-world example
60 tsp/ms × 4687.5 = 281,250 gal/h
60 teaspoons per millisecond = 281,250 gallon per hours.

Frequently asked questions
How many gallon per hours are in 1 teaspoon per millisecond?
1 teaspoon per millisecond equals 4,687.5 gallon per hours, using the exact defined conversion factor rather than an estimate.
How do I convert teaspoon per millisecond to gallon per hours?
Multiply the teaspoon per millisecond value by 4687.5. The converter above does this instantly to whatever precision you set.
How do I convert gallon per hours back to teaspoon per millisecond?
Use the reverse factor: 1 gallon per hours equals 0.0002133333 teaspoons per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a teaspoon per millisecond?
Teaspoon per Millisecond (tsp/ms) is a unit of flow rate.
What is a gallon per hours?
Gallon per Hours (gal/h) is a unit of flow rate.
Is the teaspoon per millisecond to gallon per hours conversion exact?
Yes. Both teaspoon per millisecond and gallon per hours are defined by fixed standards rather than physical artifacts, so the factor of 4687.5 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.
