Converting from Mach number ((M)*) to Hours per kilometer (h/km) in Speed

What is Mach number ((M)*)

Mach number ((M)*) is a dimensionless quantity representing the ratio of the speed of an object to the speed of sound in the medium it is traveling through.

What is Hours per kilometer (h/km)

Hours per kilometer (h/km) is a unit of speed measurement that indicates the time it takes for an object to travel one kilometer.

Conversion Formulas

The default conversion between Mach number ((M)*) and Hours per kilometer (h/km) is:

• 1((M)∗)=0.0008162972 (h/km)

• 1(h/km)=0.0008162972 ((M)∗)

Other conversion examples include:

• 9 ((M)*) = 0.00009069969 (h/km)
• 9 (h/km) = 0.00009069969 ((M)*)
• 8 ((M)*) = 0.0001020372 (h/km)
• 8 (h/km) = 0.0001020372 ((M)*)
• 14 ((M)*) = 0.00005830694 (h/km)
• 14 (h/km) = 0.00005830694 ((M)*)

Examples

1. Convert 5 ((M)*) to h/km:

5 ((M)∗)×0.0008162972=0.004081486 (h/km)

2. Convert 0.0005 h/km to ((M)*):

0.0005 (h/km)×1225.080002=0.612540001 ((M)∗)

These formulas can be used to convert between Mach number ((M)*) and Hours per kilometer (h/km) for speed measurements.
