Ekuqaleni kwekhulu le-18, ama-micrometer angena esigabeni sokukhiqiza ekuthuthukisweni kwemboni yamathuluzi omshini. Kuze kube namuhla, i-micrometer isalokhu ingelinye lamathuluzi okulinganisa ukunemba ahlukahlukene kakhulu endaweni yokusebenzela. Manje ake sibone ukuthi i-micrometer yazalwa kanjani.
Abantu baqale basebenzisa isimiso sentambo ukukala ubude bezinto ngekhulu le-17. Ngo-1638, uW. Gascogine, isazi sezinkanyezi saseYorkshire, eNgilandi, wasebenzisa isimiso sentambo ukuze alinganise ibanga lezinkanyezi. Kamuva, ngo-1693, wasungula umbusi wokulinganisa obizwa ngokuthi "i-caliper micrometer".
Lena isistimu yokulinganisa ene-shaft enentambo exhunywe kwisondo lesandla elizungezayo ekugcineni kanye nemihlathi enyakazayo kwenye. Ukufundwa kokulinganisa kungatholwa ngokubala ukuzungezisa kwesondo lesandla ngokudayela kokufunda. Isonto lokudayela kokufunda lihlukaniswe izingxenye ezilinganayo ezingu-10, futhi ibanga likalwa ngokuhambisa uzipho lokulinganisa, oluqaphela umzamo wokuqala wabantu wokulinganisa ubude ngentambo yesikulufu.
Amathuluzi okulinganisa ukunemba abengatholakali kwezohwebo kwaze kwaba sekupheleni kwekhulu le-19. USir Joseph Whitworth, owasungula intambo edumile ethi "Whitworth", waba umuntu ohamba phambili ekukhuthazeni ukuthengiswa kwama-micrometer. UBrown & Sharpe we-American B&S Company bavakashele iParis International Exposition eyabanjwa ngo-1867, lapho babona khona i-micrometer ye-Palmer okokuqala futhi bayibuyisela e-United States. UBrown & Sharpe bahlolisise imakhromitha ababebuya nayo eParis base bengeza izindlela ezimbili kuyo: indlela yokulawula kangcono i-spindle kanye nelokhi yokuphotha. Bakhiqiza i-pocket micrometer ngo-1868 futhi bayiletha emakethe ngonyaka olandelayo.
Kusukela lapho, isidingo sama-micrometers kuma-workshops okwenziwa kwemishini siye sabikezelwa ngokunembile, futhi ama-micrometer afanele izilinganiso ezihlukahlukene asetshenziswe kabanzi ngokuthuthukiswa kwamathuluzi omshini.
