Isisindo seshidi le-aluminium engu-16-gauge sizoncika kubukhulu balo (ubude, ububanzi) kanye ne-alloy ethile ye-aluminium esetshenzisiwe. Ubukhulu be 16-ishidi le-aluminium gauge cishe 0.0508 amayintshi noma 1.29 amamilimitha. Ukubala isisindo, ungasebenzisa ifomula elandelayo:
Ubunzima (ngamaphawundi) = Ubude (ngamayintshi) x Ububanzi (ngamayintshi) x Ubukhulu (ngamayintshi) x Ukuminyana (ngamaphawundi ayi-cubic inch ngayinye)
Ubuningi be-aluminium cishe 0.098 amakhilogremu nge-intshi ngayinye ye-cubic.
Ngakho-kunjalo, uma unobukhulu beshidi lakho le-aluminium engu-16 gauge, ungakwazi ukubala isisindo usebenzisa le fomula. Ngokwesibonelo, uma unalo ishidi lokho 48 amasentimitha ubude futhi 24 amayintshi ububanzi:
Isisindo = 48 amayintshi x 24 amayintshi x 0.0508 amayintshi x 0.098 amaphawundi kuyi-cubic inch = 59.06 amakhilogremu
Lesi isisindo sethiyori, futhi izisindo zangempela zingahluka kancane kuye ngokuthi ingxubevange ethile nanoma ikuphi okunamathelayo noma ukwelapha okusetshenziswe eshidini le-aluminium..
