About Converting Quart per Weeks to Quarts per Millisecond
Quart per Weeks and Quart 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
quarts per millisecond = quart per weeks × 1.653439e-9
This factor comes from each unit's defined relationship to the category's base unit: 1 quart per weeks equals 1.564737e-9 base units, and 1 quart per millisecond equals 0.946352946 base units, so dividing one by the other gives the direct quart per weeks-to-quart per millisecond factor of 1.653439e-9.
Simple example
1 qt/wk × 1.653439e-9 = 1.653439e-9 qt/ms
1 quart per weeks = 1.653439e-9 quarts per millisecond.
Real-world example
60 qt/wk × 1.653439e-9 = 9.920635e-8 qt/ms
60 quart per weeks = 9.920635e-8 quarts per millisecond.

Frequently asked questions
How many quarts per millisecond are in 1 quart per weeks?
1 quart per weeks equals 1.653439e-9 quarts per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert quart per weeks to quart per millisecond?
Multiply the quart per weeks value by 1.653439e-9. The converter above does this instantly to whatever precision you set.
How do I convert quart per millisecond back to quart per weeks?
Use the reverse factor: 1 quart per millisecond equals 604,800,000 quart per weeks. You can also use the swap control in the converter above to flip the direction instantly.
What is a quart per weeks?
Quart per Weeks (qt/wk) is a unit of flow rate.
What is a quart per millisecond?
Quart per Millisecond (qt/ms) is a unit of flow rate.
Is the quart per weeks to quart per millisecond conversion exact?
Yes. Both quart per weeks and quart 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.
