About Converting Cup per Days to Tablespoon per Seconds
Cup per Days and Tablespoon 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
tablespoon per seconds = cup per days × 0.000185185185185
This factor comes from each unit's defined relationship to the category's base unit: 1 cup per days equals 2.73829e-9 base units, and 1 tablespoon per seconds equals 0.0000147867647813 base units, so dividing one by the other gives the direct cup per days-to-tablespoon per seconds factor of 0.000185185185185.
Simple example
1 cup/d × 0.0001851851852 = 0.0001851852 tbsp/s
1 cup per days = 0.0001851852 tablespoon per seconds.
Real-world example
60 cup/d × 0.0001851851852 = 0.0111111111 tbsp/s
60 cup per days = 0.0111111111 tablespoon per seconds.

Frequently asked questions
How many tablespoon per seconds are in 1 cup per days?
1 cup per days equals 0.0001851852 tablespoon per seconds, using the exact defined conversion factor rather than an estimate.

Multiply the cup per days value by 0.0001851851852. The converter above does this instantly to whatever precision you set.
How do I convert tablespoon per seconds back to cup per days?
Use the reverse factor: 1 tablespoon per seconds equals 5,400 cup per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a cup per days?
Cup per Days (cup/d) is a unit of flow rate.
What is a tablespoon per seconds?
Tablespoon per Seconds (tbsp/s) is a unit of flow rate.
Is the cup per days to tablespoon per seconds conversion exact?
Yes. Both cup per days and tablespoon per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.0001851851852 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.
