1. Nyhav ib meter ntawm round steel=0.00617 × txoj kab uas hla × txoj kab uas hla
Kauv steel yeeb nkab nyhav ib 'meter' {{0}} (inch - phab ntsa thickness) * phab ntsa thickness * 0.02466
2. Nyhav ib ' meter ' square steel=0.00786 × sab dav × sab dav
3. Qhov hnyav ntawm hexagonal steel ib m=0.0068 × txoj kab uas hla ntawm sab nraud × txoj kab uas hla ntawm sab nraud
4. Nyhav ib meter ntawm octagonal steel=0.0065 × txoj kab uas hla × txoj kab uas hla
5. Nyhav ib 'meter' ntawm rebar=0.00617 × txoj kab uas hla × txoj kab uas hla
6. Nyhav ib 'meter' ntawm equilateral kaum steel=sab dav × sab thickness × 0.015
7. Nyhav ib 'meter' ntawm ca steel=0.00785 × thickness × dav
8. Nyhav ib m ntawm seamless steel yeeb nkab=0.02466 × phab ntsa thickness × (sab nraud txoj kab uas hla - phab ntsa thickness)
9. Nyhav ib meter ntawm hluav taws xob welded steel=seamless steel yeeb nkab
10. Steel phaj hnyav ib square meter=7.85 × thickness
11. Brass raj: hnyav ib 'meter'=0.02670 * phab ntsa thickness * (sab nraud txoj kab uas hla-phab ntsa thickness)
12. Copper raj: hnyav ib 'meter'=0.02796 * phab ntsa thickness * (sab nraud txoj kab uas hla-phab ntsa thickness)
Lub cev hnyav ntawm lub kauv raj:
(Ob txoj kab uas hla-phab ntsa thickness) * phab ntsa thickness * 0.0246615
Piv txwv li, ib lub meter kauv raj yog 820 * 10
(Ob txoj kab uas hla - phab ntsa thickness) * phab ntsa thickness * 0 02466+0.51
Siv rau cov lus qhia saum toj no: ({{0}})*10*0.02466+0.51=200.25kg
