About Converting Teaspoon per Days to Milliliter per Days
Teaspoon per Days and Milliliter per Days 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
milliliter per days = teaspoon per days × 4.92892159375
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 milliliter per days equals 1.157407e-11 base units, so dividing one by the other gives the direct teaspoon per days-to-milliliter per days factor of 4.92892159375.
Simple example
1 tsp/d × 4.928921594 = 4.928921594 mL/d
1 teaspoon per days = 4.928921594 milliliter per days.
Real-world example
60 tsp/d × 4.928921594 = 295.7352956 mL/d
60 teaspoon per days = 295.7352956 milliliter per days.

Frequently asked questions
How many milliliter per days are in 1 teaspoon per days?
1 teaspoon per days equals 4.928921594 milliliter per days, using the exact defined conversion factor rather than an estimate.
How do I convert teaspoon per days to milliliter per days?
Multiply the teaspoon per days value by 4.928921594. The converter above does this instantly to whatever precision you set.
How do I convert milliliter per days back to teaspoon per days?
Use the reverse factor: 1 milliliter per days equals 0.2028841362 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 milliliter per days?
Milliliter per Days (mL/d) is a unit of flow rate.
Is the teaspoon per days to milliliter per days conversion exact?
Yes. Both teaspoon per days and milliliter per days are defined by fixed standards rather than physical artifacts, so the factor of 4.928921594 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.
