How to Convert Femtometer per second to Mach number

1 fms = 2.91e-18 mach

Understand the base relationship:
1 Femtometer per second = 1.00e-15 meters per second
1 Mach number = 343.200 meters per second
Establish the conversion factor:
1 fms = (1.00e-15 m/s) / (343.200 m/s/mach) = 2.91e-18 mach
Apply the conversion:
Multiply the value in fms by 2.91e-18 to get the equivalent in mach

Convert 5 fms to mach:

5 fms × 2.91e-18 = 1.46e-17 mach
