Decimeter er lig med 10-1 meter (længdeenhed), kommer fra en kombination af det metriske præfiks deci (d) og SI enhedens længde meter (m).

Tommerne (forkortelse: in eller ") er en længde i de britiske imperialistiske og USAs almindelige målesystemer, der nu formelt svarer til 1/36 yards, men normalt forstået som 1/12 af en fod. Afledt af den romerske uncia ("tolvte") bruges tommer også til tider til at oversætte relaterede enheder i andre målesystemer, som normalt forstås som hidrørende fra den menneskelige tommers bredde.
