Steel coil a n-gun hpe sawn la na matu formula gaw: N-gun (kg)=Galu (mm) × N-gun (mm) × Galu (m) × N-gun (g/cm3) × 0.001 re. Ga shadawn, shinggyim masha ni lang ai carbon n-gang (density 7.85 g/cm3) a matu, coil gaw 1000 mm dam nna, 1 mm galu nna, 200 m galu ai rai yang, n-gun=1000 × 1 × 200 × 7.85 × 0.001=1570 kg rai na re.
Myit yu na lam: 1. Density manu ni hpe n-gun atsam hpe madung tawn nna galai shai ra ai (ga shadawn, n-gun n rawng ai n-gang gaw 7.93 g/cm3);
2. Galu kaba ai hpe madung hku nna lawu na formula hpe lang nna coil a shinggan n-gup magap hpe madung tawn nna sawn la ai: Galu kaba ai (m)=(Shinggan n-gup magap2 - Kata n-gup magap2) × 0.7854 ÷ Galu kaba ai (mm) ÷ 1000;
3. Industry gaw ±5% hkam sharang lu ai ahkang jaw ai. Ya aten hta anhte gaw gat seng ni hta magri hpe jasan jaseng ai arung arai ni hpe jaw nga ga ai. Ndai arung arai ni gaw, n-gun ja ai -htuk manu ai ntsin formula hpe lang nna, n-gun ja ai ntsin formula hpe lang nna, 25 kg barrel ni hta, bungli galaw ai shara ni hta jai lang na matu lu mai ai.
