&lt;p&gt;&lt;b&gt;Pàgina nova&lt;/b&gt;&lt;/p&gt;&lt;div&gt;&amp;#039;&amp;#039;&amp;#039;Parts per milló&amp;#039;&amp;#039;&amp;#039; (ppm), és una unitat de mida que es referix als mg (miligrams) que hi ha en un kg de [[dissolució]]; com la densitat de l&amp;#039;aigua és 1, 1 kg de solució té un volum d&amp;#039;aproximadament 1 litro, els ppm són també els mg d&amp;#039;una substància en un litro expressat d&amp;#039;una atra forma, mg/l &lt;br /&gt;
(Seguint el mateix raonament, els ppm també són els grams que conté cada metro cúbic, g/m3) &lt;br /&gt;
Per a calcular els ppm es dividix el pes en mg pel volum en litros, per eixemple, una dissolució de 15 grams (g) en 3 metros cúbics d&amp;#039;aigua: &lt;br /&gt;
15 g x 1000 mg/g = 15000 mg &lt;br /&gt;
3 m3 x 1000 l/m3 = 3000 l &lt;br /&gt;
Concentració: 15000 / 3000 = 5 mg/l = 5 ppm&lt;br /&gt;
