About Converting Tablespoon per Days to Cubic inch per Weeks
Tablespoon per Days and Cubic inch per Weeks 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
cubic inch per weeks = tablespoon per days × 6.31640625
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 cubic inch per weeks equals 2.709501e-11 base units, so dividing one by the other gives the direct tablespoon per days-to-cubic inch per weeks factor of 6.31640625.
Simple example
1 tbsp/d × 6.31640625 = 6.31640625 in3/wk
1 tablespoon per days = 6.31640625 cubic inch per weeks.
Real-world example
60 tbsp/d × 6.31640625 = 378.984375 in3/wk
60 tablespoon per days = 378.984375 cubic inch per weeks.

What is a tablespoon per days?
Tablespoon per Days (tbsp/d) is a unit of flow rate.
What is a cubic inch per weeks?
Cubic inch per Weeks (in3/wk) is a unit of flow rate.
Is the tablespoon per days to cubic inch per weeks conversion exact?
Yes. Both tablespoon per days and cubic inch per weeks are defined by fixed standards rather than physical artifacts, so the factor of 6.31640625 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.
