About Converting Gallon per Days to Teaspoons per Millisecond
Gallon per Days and Teaspoon 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
teaspoons per millisecond = gallon per days × 0.00000888888888889
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per days equals 4.381264e-8 base units, and 1 teaspoon per millisecond equals 0.00492892159375 base units, so dividing one by the other gives the direct gallon per days-to-teaspoon per millisecond factor of 0.00000888888888889.
Simple example
1 gal/d × 0.000008888888889 = 0.0000088889 tsp/ms
1 gallon per days = 0.0000088889 teaspoons per millisecond.
Real-world example
60 gal/d × 0.000008888888889 = 0.0005333333 tsp/ms
60 gallon per days = 0.0005333333 teaspoons per millisecond.

Frequently asked questions
How many teaspoons per millisecond are in 1 gallon per days?
1 gallon per days equals 0.0000088889 teaspoons per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per days to teaspoon per millisecond?
Multiply the gallon per days value by 0.000008888888889. The converter above does this instantly to whatever precision you set.
How do I convert teaspoon per millisecond back to gallon per days?
Use the reverse factor: 1 teaspoon per millisecond equals 112,500 gallon per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per days?
Gallon per Days (gal/d) is a unit of flow rate.
What is a teaspoon per millisecond?
Teaspoon per Millisecond (tsp/ms) is a unit of flow rate.
Is the gallon per days to teaspoon per millisecond conversion exact?
Yes. Both gallon per days and teaspoon per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.000008888888889 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.
