Como 1 mL de \u00e1gua pesa 1 g, 1 mL cont\u00e9m 1000 mg, de modo que, para a \u00e1gua, o valor em mg e o valor em mL s\u00e3o numericamente iguais. Outros l\u00edquidos s\u00e3o diferentes: 1 mL de mel pesa cerca de 1,42 g (1420 mg), enquanto 1 mL de \u00f3leo de cozinha pesa cerca de 0,92 g (920 mg). A calculadora traz valores predefinidos para essas subst\u00e2ncias comuns \u00e0 temperatura ambiente.<\/p>\n<p>Interpretar o resultado \u00e9 simples: dividir uma massa pela concentra\u00e7\u00e3o (ou pela densidade em mg\/mL) indica quanto l\u00edquido medir; multiplicar um volume pela concentra\u00e7\u00e3o indica quanto princ\u00edpio ativo esse volume cont\u00e9m.
