Dyma fesuriad o gyflymder a ddefnyddir fel mater o drefn mewn gwledydd nad ydynt yn defnyddio'r system fetrig ar gyfer trafnidiaeth fel Unol Daleithiau America. Mae'r Deyrnas Unedig hefyd yn defnyddio hwn ar y ffyrdd er bod y system fetrig wedi'i mabwysiadu'n swyddogol. Rhoddir terfynau cyflymder ar y ffyrdd fesul milltir yr awr a gaiff ei dalfyrru fel mya neu mi/a.
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.
