I-screw micrometer isebenzisa amayunithi e-millimeter futhi isikali sayo esincane kunazo zonke singamamilimitha angu-0,01.
Isikali esiyinhloko = amamilimitha angu-4,5
Isikali esijikelezayo = 27,5 x 0,01 millimeters = 0,275 millimeters
Umphumela wokulinganisa = 4,5 millimeters + 0,275 millimeters = 4,775 millimeters = 4,78 millimeters
Impendulo efanele ngu-A.
