What does Mach (SI standard) represent?

Mach (SI standard) is a dimensionless number expressing an object's speed relative to the local speed of sound, which depends on the surrounding medium's temperature and composition.

What is first cosmic velocity?

First cosmic velocity is the minimum tangential speed an object requires at a celestial body's surface to maintain a stable circular orbit, calculated using the body's gravitational parameters.

Why convert Mach to first cosmic velocity?

This conversion links speeds relative to sound in the atmosphere to the orbital speeds needed for spacecraft mission planning, helping aerospace engineers design and analyze flight and propulsion systems.
