About Converting Teaspoon per Days to Imperial gallon per Seconds
Teaspoon per Days and Imperial gallon 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
imperial gallon per seconds = teaspoon per days × 1.254874e-8
This factor comes from each unit's defined relationship to the category's base unit: 1 teaspoon per days equals 5.70477e-11 base units, and 1 imperial gallon per seconds equals 0.00454609 base units, so dividing one by the other gives the direct teaspoon per days-to-imperial gallon per seconds factor of 1.254874e-8.
Simple example
1 tsp/d × 1.254874e-8 = 1.254874e-8 imp gal/s
1 teaspoon per days = 1.254874e-8 imperial gallon per seconds.
Real-world example
60 tsp/d × 1.254874e-8 = 7.529244e-7 imp gal/s
60 teaspoon per days = 7.529244e-7 imperial gallon per seconds.

Frequently asked questions
How many imperial gallon per seconds are in 1 teaspoon per days?
1 teaspoon per days equals 1.254874e-8 imperial gallon per seconds, using the exact defined conversion factor rather than an estimate.

Multiply the teaspoon per days value by 1.254874e-8. The converter above does this instantly to whatever precision you set.
How do I convert imperial gallon per seconds back to teaspoon per days?
Use the reverse factor: 1 imperial gallon per seconds equals 79,689,272.5 teaspoon per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a teaspoon per days?
Teaspoon per Days (tsp/d) is a unit of flow rate.
What is a imperial gallon per seconds?
Imperial gallon per Seconds (imp gal/s) is a unit of flow rate.
Is the teaspoon per days to imperial gallon per seconds conversion exact?
Yes. Both teaspoon per days and imperial gallon per seconds are defined by fixed standards rather than physical artifacts, so the factor of 1.254874e-8 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.
