About Converting Millimeter per Seconds to Maches
Millimeter per Seconds and Mach both describe speed, and the conversion matters whenever a maritime or aviation speed (knots) needs to be compared against a road speed (mph). Specifically: Distance divided by time, and mach at standard sea-level conditions.
Formula
maches = millimeter per seconds × 0.00000293866995798
This factor comes from each unit's defined relationship to the category's base unit: 1 millimeter per seconds equals 0.001 base units, and 1 mach equals 340.29 base units, so dividing one by the other gives the direct millimeter per seconds-to-mach factor of 0.00000293866995798.
Simple example
1 mm/s × 0.000002938669958 = 0.0000029387 Ma
1 millimeter per seconds = 0.0000029387 maches.
Real-world example
10 mm/s × 0.000002938669958 = 0.0000293867 Ma
10 millimeter per seconds = 0.0000293867 maches.

Reverse conversion: Mach to Millimeter per Seconds
0.0000029387 Ma × 340290 = 1.000010223 mm/s
0.0000029387 maches = 1.000010223 millimeter per seconds.
millimeter per seconds = maches × 340290
