Qhov kev hloov dua siab tshiab tshaj plaws ntawm metric, American thiab imperial threads ntawm cov xov sib txawv hauv keeb kwm

1 nti = 25.4 mm

Piv txwv li: Yog hais tias koj xav hloov ib tug US xov (xov xwm american) nrog ib txoj kab uas hla ntawm 10 ntiv mus rau ametric xov, peb tuaj yeem muab txoj kab uas hla los ntawm 25.4, uas yog 10 × 25.4 = 254 mm;Yog hais tias peb xav hloov ib tug metric xov nrog ib txoj kab uas hla ntawm 10 hli los ua American threads, peb tsuas yog yuav tsum tau faib nws txoj kab uas hla los ntawm 25.4, uas yog 10÷25.4 = 0.3937 ntiv tes.
