About Converting Gallon per Weeks to Cubic Meters per Millisecond
Gallon per Weeks and Cubic Meter 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
cubic meters per millisecond = gallon per weeks × 6.258948e-12
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per weeks equals 6.258948e-9 base units, and 1 cubic meter per millisecond equals 1000 base units, so dividing one by the other gives the direct gallon per weeks-to-cubic meter per millisecond factor of 6.258948e-12.
Simple example
1 gal/wk × 6.258948e-12 = 6.258948e-12 m3/ms
1 gallon per weeks = 6.258948e-12 cubic meters per millisecond.
Real-world example
60 gal/wk × 6.258948e-12 = 3.755369e-10 m3/ms
60 gallon per weeks = 3.755369e-10 cubic meters per millisecond.

Frequently asked questions
How many cubic meters per millisecond are in 1 gallon per weeks?
1 gallon per weeks equals 6.258948e-12 cubic meters per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per weeks to cubic meter per millisecond?
Multiply the gallon per weeks value by 6.258948e-12. The converter above does this instantly to whatever precision you set.
How do I convert cubic meter per millisecond back to gallon per weeks?
Use the reverse factor: 1 cubic meter per millisecond equals 159,771,257,300 gallon per weeks. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per weeks?
Gallon per Weeks (gal/wk) is a unit of flow rate.
What is a cubic meter per millisecond?
Cubic Meter per Millisecond (m3/ms) is a unit of flow rate.
Is the gallon per weeks to cubic meter per millisecond conversion exact?
Yes. Both gallon per weeks and cubic meter per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 6.258948e-12 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.
