To convert mg/L to µg/g, you can use the following relationship:
1 mg/L = 1 µg/g
Explanation:
- 1 mg (milligram) is equal to 1000 µg (micrograms).
- 1 L (liter) of water is approximately equal to 1000 g (grams) since the density of water is 1 g/mL.
Therefore, when you express concentrations in mg/L, it can also be directly expressed as µg/g because the ratio of mass (micrograms) to mass (grams) in the context of a liter of water remains constant.
So, the conversion factor is straightforward:
1 mg/L = 1 µg/g
