Inzira yo kubara uburemere bwibyuma ni: Uburemere (kg)=Ubugari (mm) × Ubunini (mm) × Uburebure (m) × Ubucucike (g / cm³) × 0.001. Kurugero, kubyuma bisanzwe bya karubone (ubucucike 7,85 g / cm³), niba igiceri gifite ubugari bwa mm 1000, ubugari bwa mm 1, na 200 m z'uburebure, uburemere=1000 × 1 × 200 × 7.85 × 0.001=1570 kg.
Icyitonderwa: 1. Indangagaciro zubucucike zigomba guhinduka ukurikije ibikoresho (urugero, ibyuma bitagira umwanda ni 7,93 g / cm³);
2. Uburebure muri rusange bubarwa hashingiwe kuri diameter yo hanze ya coil ukoresheje formula ikurikira: Uburebure (m)=(Diameter yo hanze - Diameter y'imbere²) × 0.7854 ness Ubunini (mm) ÷ 1000;
3. Inganda zemerera ± 5% kwihanganira ibiro. Kugeza ubu dutanga ibicuruzwa byoza ibyuma mububiko. Ibicuruzwa bikoresha amata menshi - yuburyo bwiza bwamazi akwiranye no kuvura amarangi - kandi araboneka muri barrale 25 kg yo gukoresha inganda.
