About Converting Gallon per Hours to Teaspoon per Seconds
Gallon per Hours and Teaspoon per Seconds 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 seconds = gallon per hours × 0.213333333333
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per hours equals 0.00000105150327333 base units, and 1 teaspoon per seconds equals 0.00000492892159375 base units, so dividing one by the other gives the direct gallon per hours-to-teaspoon per seconds factor of 0.213333333333.
Simple example
1 gal/h × 0.2133333333 = 0.2133333333 tsp/s
1 gallon per hours = 0.2133333333 teaspoon per seconds.
Real-world example
60 gal/h × 0.2133333333 = 12.8 tsp/s
60 gallon per hours = 12.8 teaspoon per seconds.

Frequently asked questions
How many teaspoon per seconds are in 1 gallon per hours?
1 gallon per hours equals 0.2133333333 teaspoon per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per hours to teaspoon per seconds?
Multiply the gallon per hours value by 0.2133333333. The converter above does this instantly to whatever precision you set.
How do I convert teaspoon per seconds back to gallon per hours?
Use the reverse factor: 1 teaspoon per seconds equals 4.6875 gallon per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per hours?
Gallon per Hours (gal/h) is a unit of flow rate.
What is a teaspoon per seconds?
Teaspoon per Seconds (tsp/s) is a unit of flow rate.
Is the gallon per hours to teaspoon per seconds conversion exact?
Yes. Both gallon per hours and teaspoon per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.2133333333 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.
