Understanding the Conversion

Parts per trillion (pptr) is a unit of measurement used to express very small concentrations. It represents one part in one trillion (1012) parts of a whole.

Grams per kilogram (gKg) is a unit of mass concentration, representing the mass of a substance in grams per kilogram of solution or mixture.

The conversion formula is straightforward: since 1 pptr equals 1 × 10-12 gKg, you simply multiply the pptr value by 10-12 to get the equivalent in gKg.
