About Converting Teaspoon per Weeks to Teaspoons per Millisecond
Teaspoon per Weeks and Teaspoon per Millisecond 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
teaspoons per millisecond = teaspoon per weeks × 1.653439e-9
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 teaspoon per millisecond equals 0.00492892159375 base units, so dividing one by the other gives the direct teaspoon per weeks-to-teaspoon per millisecond factor of 1.653439e-9.
Simple example
1 tsp/wk × 1.653439e-9 = 1.653439e-9 tsp/ms
1 teaspoon per weeks = 1.653439e-9 teaspoons per millisecond.
Real-world example
60 tsp/wk × 1.653439e-9 = 9.920635e-8 tsp/ms
60 teaspoon per weeks = 9.920635e-8 teaspoons per millisecond.

Frequently asked questions
How many teaspoons per millisecond are in 1 teaspoon per weeks?
1 teaspoon per weeks equals 1.653439e-9 teaspoons per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert teaspoon per weeks to teaspoon per millisecond?
Multiply the teaspoon per weeks value by 1.653439e-9. The converter above does this instantly to whatever precision you set.
How do I convert teaspoon per millisecond back to teaspoon per weeks?
Use the reverse factor: 1 teaspoon per millisecond equals 604,800,000 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 teaspoon per millisecond?
Teaspoon per Millisecond (tsp/ms) is a unit of flow rate.
Is the teaspoon per weeks to teaspoon per millisecond conversion exact?
Yes. Both teaspoon per weeks and teaspoon per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 1.653439e-9 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.
