Ob chav uas feem ntau siv rau cov casters kev lag luam:
● Cov chav ntev: ib nti sib npaug rau tag nrho qhov ntev ntawm peb pob ntseg ntawm barley;
● Ib chav ntsuas qhov hnyav: ib phaus sib npaug rau 7,000 npaug ntawm qhov hnyav ntawm ib hom barley uas muab rho tawm ntawm nruab nrab ntawm pob ntseg;
Hais txog qhov ntev hauv cov chav ntsuas imperial: Tom qab xyoo 1959, nti hauv American imperial system thiab nti hauv British system tau raug qauv rau 25.4 hli rau kev siv hauv kev tshawb fawb thiab kev lag luam, tab sis American system khaws cia "nti ntsuas" siv rau hauv kev ntsuas sib txawv me ntsis.

Kev hloov pauv chav tsev yuav tsum muaj ib txoj kev paub zoo, thaum peb pom ntau dua, suav ntau dua, txawm tias tib neeg muab cov chav tsev hauv tsev lossis cov chav txawv teb chaws rau koj, koj tuaj yeem hloov pauv sai sai mus rau hauv cov chav uas koj paub zoo. Yog tias koj koom nrog kev lag luam ntawm cov neeg ua haujlwm hauv kev lag luam, koj yuav feem ntau ntsib cov nti thiab centimeters, millimeters ntawm kev hloov pauv; thiab hom chav tsev ntawm kev hloov pauv hauv kev ua haujlwm txhua hnub tsawg dua.
