Mae Mach yn fesuriad o gyflymder sy'n seiliedig ar gyflymder sain. Gan fod sain yn teithio ar gyflymder gwahanol o dan amodau gwahanol, mae'r cyfrifiadau yma yn cael eu rhoi ar sail tymheredd 20°C mewn aer sych ar lefel y môr. Defnyddir Mach fel mater o drefn yn y diwydiant awyrennau a fforio'r gofod.
