📜Etymology

The Mach number is named after the physicist and philosopher Ernst Mach , in honour of his achievements, according to a proposal by the aeronautical engineer Jakob Ackeret in 1929\. The word Mach is always capitalized since it derives from a proper name and since the Mach number is a dimensionless quantity rather than a unit of measure . This is also why the number comes after the word Mach. It was also known as Mach's number by Lockheed when reporting the effects of compressibility on the P-38 aircraft in 1942.
