Musanagwiritse ntchito choyezera choyezera, choyamba dziwani ngati cholamulira cha inchi kapena cholamulira cha centimita. Mayiko ambiri padziko lapansi amagwiritsa ntchito utali wa metric, kupatula mayiko ochepa, monga United States, omwe amagwiritsabe ntchito utali wa mfumu.
Pali mizere yambiri ndi zilembo za manambala pa wolamulira, ziro ndi chizindikiro choyambira, ikani wolamulira pa chinthucho, kapena mosemphanitsa, ikani chinthu pa wolamulira, muyenera kugwirizanitsa mzere wa ziro mpaka kumapeto kwa chinthu chanu, ndiye yang'anani mbali ina ya chinthucho, pamzere wa wihic ndi wolumikizidwa, ndiko kutalika kwake. kwa inchi wolamulira, Ngati mzere walembedwa 2, ndi kutalika kwa mainchesi 2, kwa cm wolamulira, Ngati mzere uli ndi chizindikiro 5, ndi kutalika kwa 5 cm.
Pali mizere yayifupi kwambiri pakati pa masikelo akuluakulu, ndipo omwe amagwiritsidwa ntchito kugawaniza, kwa inchi wolamulira, pakati pa chizindikiro cha 1 inchi ndi 2 mainchesi, mzerewo ndi 1/2 inchi, theka la inchi, kuwerengera kuchokera ku 0. , ndiye 1 1/2 mainchesi.
kwa cm wolamulira, pakati pa chizindikiro cha 1 cm ndi 2 cm, mzerewo ndi 0.5 cm, theka la masentimita, omwenso ndi 5 mm. kuwerengera kuchokera ku 0, ndiye 1.5 cm.
Ngati mungafune kusintha pakati pa mita, mapazi ndi mainchesi (m, ft ndi mkati), mwachitsanzo. Mamita 2.5 ndi mapazi angati? 6' 2" ndi wamtali bwanji mu mita ? yesani chosinthira mamita ndi mapazi ichi, ndi chowongolera chathu chowoneka bwino, mupeza yankho posachedwa.
