Nthowa yakupimira kulemera kwa chisulo cha chisulo ni iyi: Kulemera (kg)=Utali (mm) × Utali (mm) × Utali (m) × Utali (g/cm3) × 0.001. Mwachiyelezgero, pa chisulo cha carbon chambura kumanyikwa (ukuru wake 7.85 g/cm3), usange koyilo ni 1000 mm mu usani, 1 mm mu utali, na 200 m mu utali, kulemera kwake=1000 × 1 × 200 × 7.85 × 0.001=1570 kg.
Ziŵani kuti: 1. Vinthu vyakukwana vikwenera kusintha kuyana na ivyo vikupangika (mwachiyelezgero, chisulo chambura zimbiri ni 7.93 g/cm3);
2. Utali kanandi ukupimika mwakuyana na utali wa kuwaro kwa koyilo mwakugwiliskira nchito ndondomeko iyi: Utali (m)=(Utali Wakuwalo2 - Utali Wamukati2) × 0.7854 ÷ Utali (mm) ÷ 1000;
3. Mafakitale ghakuzomerezga ± 5% kulemera kulemera. Pasono tikupereka vyakutozga vitsulo mu masitolo. Vinthu ivi vikugwiriskira ncito mtundu wa maji ghakugwira nchito makora comene agho ghakwenelera pakupenta pambere ŵandapente ndipo vikusangika mu viŵiya vya makilogalamu 25 kuti vigwiriskike ncito mu mafakitale.
