About Converting Teaspoon per Days to Hectoliter per Seconds
Teaspoon per Days and Hectoliter 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
hectoliter per seconds = teaspoon per days × 5.70477e-10
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 hectoliter per seconds equals 0.1 base units, so dividing one by the other gives the direct teaspoon per days-to-hectoliter per seconds factor of 5.70477e-10.
Simple example
1 tsp/d × 5.70477e-10 = 5.70477e-10 hL/s
1 teaspoon per days = 5.70477e-10 hectoliter per seconds.
Real-world example
60 tsp/d × 5.70477e-10 = 3.422862e-8 hL/s
60 teaspoon per days = 3.422862e-8 hectoliter per seconds.

Frequently asked questions
How many hectoliter per seconds are in 1 teaspoon per days?
1 teaspoon per days equals 5.70477e-10 hectoliter per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert teaspoon per days to hectoliter per seconds?
Multiply the teaspoon per days value by 5.70477e-10. The converter above does this instantly to whatever precision you set.
How do I convert hectoliter per seconds back to teaspoon per days?
Use the reverse factor: 1 hectoliter per seconds equals 1,752,918,937 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 hectoliter per seconds?
Hectoliter per Seconds (hL/s) is a unit of flow rate.
Is the teaspoon per days to hectoliter per seconds conversion exact?
Yes. Both teaspoon per days and hectoliter per seconds are defined by fixed standards rather than physical artifacts, so the factor of 5.70477e-10 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.
