About Converting Tablespoon per Days to Teaspoon per Days
Tablespoon per Days and Teaspoon 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
teaspoon per days = tablespoon per days × 3
This factor comes from each unit's defined relationship to the category's base unit: 1 tablespoon per days equals 1.711431e-10 base units, and 1 teaspoon per days equals 5.70477e-11 base units, so dividing one by the other gives the direct tablespoon per days-to-teaspoon per days factor of 3.
Simple example
1 tbsp/d × 3 = 3 tsp/d
1 tablespoon per days = 3 teaspoon per days.
Real-world example
60 tbsp/d × 3 = 180 tsp/d
60 tablespoon per days = 180 teaspoon per days.

Frequently asked questions
How many teaspoon per days are in 1 tablespoon per days?
1 tablespoon per days equals 3 teaspoon per days, using the exact defined conversion factor rather than an estimate.
How do I convert tablespoon per days to teaspoon per days?
Multiply the tablespoon per days value by 3. The converter above does this instantly to whatever precision you set.
How do I convert teaspoon per days back to tablespoon per days?
Use the reverse factor: 1 teaspoon per days equals 0.3333333333 tablespoon per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a tablespoon per days?
Tablespoon per Days (tbsp/d) is a unit of flow rate.
What is a teaspoon per days?
Teaspoon per Days (tsp/d) is a unit of flow rate.
Is the tablespoon per days to teaspoon per days conversion exact?
Yes. Both tablespoon per days and teaspoon per days are defined by fixed standards rather than physical artifacts, so the factor of 3 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.
