2. Píopa Babhta Cruach Dhosmálta foirmle ríomh meáchain eile:
Foirmle: (trastomhas seachtrach cearnógach – trastomhas istigh cearnógach) × fad (m) × 0.25*π
M.sh: 114mm (trastomhas seachtrach) × 4mm (tiús balla) × 6m (fad)
Ríomh: (114*114-106*106) × 6 ×0.00793= 83.74 (kg)
* I gcás 316, 316L, 310S, 309S, etc., comhéifeacht / cóimheas = 0.00793
Is féidir le dhá mhodh ríomha éagsúla torthaí comhchosúla a fháil，Mar sin féin, tá na comhéifeachtaí tagartha comhfhreagracha difriúil agus ní mór iad a mheabhrú
