Medir<\/strong> es comparar una magnitud<\/strong> con otra que llamamos unidad<\/strong>.<\/p>\n

La medida<\/strong> es el n\u00famero de veces que la magnitud<\/strong> contiene a la unidad.<\/p>\n

Las unidades de medida m\u00e1s usuales son las del Sistema M\u00e9trico Decimal<\/a>, en los pa\u00edses anglosajones se emplea el Sistema Ingl\u00e9s<\/a>. En algunas zonas rurales a\u00fan se utilizan las unidades tradicionales<\/a>.<\/p>\n
