O a\u00e7o de armadura quase sempre \u00e9 comprado e cotado pelo peso (por kg ou por tonelada), por isso converter uma lista de barras para quilogramas \u00e9 essencial para o or\u00e7amento e para conferir as entregas na obra.<\/p>\n<p>O c\u00e1lculo \u00e9 simples: um vergalh\u00e3o \u00e9 um cilindro comprido, ent\u00e3o o volume \u00e9 a \u00e1rea da se\u00e7\u00e3o transversal \\( \\pi d^{2}\/4 \\) vezes o comprimento, e o peso \u00e9 esse volume multiplicado pela densidade do a\u00e7o.

Para uma barra de 16 mm isso d\u00e1 \\( 256\/162 \\approx 1.58 \\) kg\/m, valor que coincide com o exato de 1,578 kg\/m.
