What does Mach (20°C, 1 atm) represent?

It is a speed ratio relative to the speed of sound in dry air at 20°C and 1 atmosphere, used to classify different flow regimes.

What is the significance of the second cosmic velocity?

It is the minimum speed needed for an object to escape a celestial body's gravity without further propulsion.

Can this tool be used for precise engineering calculations?

No, the conversion is intended for conceptual comparisons and may not provide exact values for precision engineering.
