* Ríomhtar toradh an chodáin trí na orlach deachúil a shlánú go dtí an codán 1/64 is gaire.
Tá 1 milliméadar cothrom le 0.03937007874 orlach:
1mm = (1 / 25.4) ″ = 0.03937007874 ″
Tá an fad d in orlach (″) cothrom leis an bhfad d i milliméadair (mm) arna roinnt ar 25.4:
d (″) = d (mm) / 25.4
Tiontaigh 20 mm go orlach:
d (″) = 20mm / 25.4 = 0.7874 ″
Déantar na orlach codáin a shlánú go taifeach 1/64.
