PPM en PPB
Saisissez une valeur en Parts Per Million (PPM) pour une conversion instantanée et précise en Parts Per Billion (PPB).
Comment fonctionne PPM en PPB
Pour convertir des PPM en PPB, appliquez 3 étapes : identifiez la valeur en PPM, multipliez par 1,000 et lisez le résultat en PPB.
Identifiez la valeur en PPM
Enregistrez la valeur de concentration en Parts Per Million. Les PPM représentent 1 partie de soluté pour 1,000,000 (10⁶) parties de solution, ce qui équivaut à 1 mg/L pour les solutions aqueuses diluées ou à 1 mg/kg pour les échantillons solides.
Multipliez par 1,000
Appliquez le facteur de conversion de 1,000 (10³). Ce facteur existe car 1 milliard est exactement 1,000 fois plus grand qu'un million. La multiplication convertit l'unité la plus grande de PPM en l'unité la plus fine de PPB.
Lisez le résultat en PPB
Le résultat est la concentration exprimée en Parts Per Billion. Les PPB offrent une résolution 1,000 fois plus fine que les PPM et équivalent à 1 µg/L pour les solutions aqueuses ou à 1 µg/kg pour les échantillons solides.
