O le fua fa'atatau mo le fa'atatauina o le mamafa o le u'amea u'amea o le: Mamafa (kg)=Lautele (mm) × Mafiafia (mm) × Umi (m) × To'atele (g/cm³) × 0.001. Mo se fa'ata'ita'iga, mo u'amea masani masani (density 7.85 g/cm³), afai o le coil e 1000 mm lautele, 1 mm mafiafia, ma 200 m le umi, o le mamafa=1000 × 1 × 200 × 7.85 × 0.001=1570 kg.
Fa'aaliga: 1. E mana'omia ona fetu'una'i le aofa'i o mea fa'atatau (mo se fa'ata'ita'iga, u'amea u'amea ole 7.93 g/cm³);
2. O le umi e masani ona fuafuaina e fa'atatau i le lautele pito i fafo o le u'amea e fa'aaoga ai le fua fa'atatau: Umi (m)=(Outer Diameter² - Inner Diameter²) × 0.7854 ÷ Mafiafia (mm) ÷ 1000;
3. O le alamanuia e faʻatagaina se ± 5% faʻapalepale mamafa. Matou te ofoina atu nei mea fa'amama u'amea i faleoloa. O nei oloa e fa'aogaina ai le maualuga-susu fa'asusu e talafeagai mo togafitiga a'o le'i-vali ma o lo'o avanoa i paelo 25 kilokalama mo le fa'aogaina o fale gaosimea.
