Show the conversion factor to convert mg/L to ug/g ?

1 answer

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
