Frequently asked questions
What is the source unit in this conversion?
The source unit is cubic millimeters per hour (mm3/h). The Cubic Millimeter (mm3) is a unit of volume. The Hour (h) is a unit of time.
What is the destination unit in this conversion?
The destination unit is cubic kilometers per millisecond (km3/ms). The Cubic Kilometer (km3) is a unit of volume. The Millisecond (ms) is a unit of time.
How do I convert cubic millimeters per hour to cubic kilometers per millisecond?
Multiply the cubic millimeters per hour value by 2.77778e-25 to get cubic kilometers per millisecond. For example, 10 mm3/h × 2.77778e-25 = 2.77778e-24 km3/ms.
Is the cubic millimeters per hour to cubic kilometers per millisecond conversion exact?
It's exact under the SI-based volume and time definitions used here, since both units convert to cubic meters per second through fixed, non-rounded factors.
Where is this conversion commonly used?
Flow rate conversions like this are used in plumbing, HVAC, irrigation, chemical processing, fuel and water metering, and engineering flow calculations.
Can I convert cubic kilometers per millisecond back to cubic millimeters per hour?
Yes. Divide the cubic kilometers per millisecond value by 2.77778e-25 (or multiply by 3.6e+24) to get cubic millimeters per hour.

About this conversion
This page converts cubic millimeters per hour (mm3/h) into cubic kilometers per millisecond (km3/ms), two units of volumetric flow rate.
The Cubic Millimeter (mm3) is a unit of volume. The Hour (h) is a unit of time.
The Cubic Kilometer (km3) is a unit of volume. The Millisecond (ms) is a unit of time.
The formula is km3/ms = mm3/h × 2.77778e-25, based on the fixed relationship between these two flow rate units.
Flow rate is calculated as a volume unit divided by a time unit, so every combination of a volume unit and a time unit forms a valid, exact flow rate unit.
