About Converting Teaspoon per Weeks to Cubic Millimeter per Years
Teaspoon per Weeks and Cubic Millimeter per Years 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 millimeter per years = teaspoon per weeks × 257178.806458
This factor comes from each unit's defined relationship to the category's base unit: 1 teaspoon per weeks equals 8.149672e-12 base units, and 1 cubic millimeter per years equals 3.168874e-17 base units, so dividing one by the other gives the direct teaspoon per weeks-to-cubic millimeter per years factor of 257178.806458.
Simple example
1 tsp/wk × 257178.8065 = 257,178.8065 mm3/yr
1 teaspoon per weeks = 257,178.8065 cubic millimeter per years.
Real-world example
60 tsp/wk × 257178.8065 = 15,430,728.39 mm3/yr
60 teaspoon per weeks = 15,430,728.39 cubic millimeter per years.

Frequently asked questions
How many cubic millimeter per years are in 1 teaspoon per weeks?
1 teaspoon per weeks equals 257,178.8065 cubic millimeter per years, using the exact defined conversion factor rather than an estimate.
How do I convert teaspoon per weeks to cubic millimeter per years?
Multiply the teaspoon per weeks value by 257178.8065. The converter above does this instantly to whatever precision you set.
How do I convert cubic millimeter per years back to teaspoon per weeks?
Use the reverse factor: 1 cubic millimeter per years equals 0.0000038883 teaspoon per weeks. You can also use the swap control in the converter above to flip the direction instantly.
What is a teaspoon per weeks?
Teaspoon per Weeks (tsp/wk) is a unit of flow rate.
What is a cubic millimeter per years?
Cubic Millimeter per Years (mm3/yr) is a unit of flow rate.
Is the teaspoon per weeks to cubic millimeter per years conversion exact?
Yes. Both teaspoon per weeks and cubic millimeter per years are defined by fixed standards rather than physical artifacts, so the factor of 257178.8065 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.
