About Converting Cubic Millimeters per Millisecond to Cubic Meter per Seconds
Cubic Millimeter per Millisecond and Cubic Meter per Seconds 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 meter per seconds = cubic millimeters per millisecond × 0.000001
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic millimeter per millisecond equals 0.000001 base units, and 1 cubic meter per seconds equals 1 base unit, so dividing one by the other gives the direct cubic millimeter per millisecond-to-cubic meter per seconds factor of 0.000001.
Simple example
1 mm3/ms × 0.000001 = 0.000001 m3/s
1 cubic millimeter per millisecond = 0.000001 cubic meter per seconds.
Real-world example
60 mm3/ms × 0.000001 = 0.00006 m3/s
60 cubic millimeters per millisecond = 0.00006 cubic meter per seconds.
Conversion table
| Cubic Millimeter per Millisecond (mm3/ms) | Cubic Meter per Seconds (m3/s) |
|---|---|
| 0.1 mm3/ms | 1e-7 m3/s |
| 1 mm3/ms | 0.000001 m3/s |
| 10 mm3/ms | 0.00001 m3/s |
| 60 mm3/ms | 0.00006 m3/s |
| 100 mm3/ms | 0.0001 m3/s |
| 1,000 mm3/ms | 0.001 m3/s |
Reverse conversion: Cubic Meter per Seconds to Cubic Millimeter per Millisecond
0.000001 m3/s × 1000000 = 1 mm3/ms
0.000001 cubic meter per seconds = 1 cubic millimeter per millisecond.
cubic millimeters per millisecond = cubic meter per seconds × 1000000

Frequently asked questions
How many cubic meter per seconds are in 1 cubic millimeter per millisecond?
1 cubic millimeter per millisecond equals 0.000001 cubic meter per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert cubic millimeter per millisecond to cubic meter per seconds?
Multiply the cubic millimeter per millisecond value by 0.000001. The converter above does this instantly to whatever precision you set.
How do I convert cubic meter per seconds back to cubic millimeter per millisecond?
Use the reverse factor: 1 cubic meter per seconds equals 1,000,000 cubic millimeters per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic millimeter per millisecond?
Cubic Millimeter per Millisecond (mm3/ms) is a unit of flow rate.
What is a cubic meter per seconds?
Cubic Meter per Seconds (m3/s) measures volumetric flow rate. The SI coherent unit for volumetric flow rate — one cubic meter of volume passing a point every second. It is classified as a SI coherent derived unit.
Is the cubic millimeter per millisecond to cubic meter per seconds conversion exact?
Yes. Both cubic millimeter per millisecond and cubic meter per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.000001 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.
