You can convert ng/mL to mg/L by (1) multiplying the values in ng/mL by 0.001 or (2) dividing the values in mg/mL by 1000.

Aedrian Abrilla thanks, yes, that is the standard method. However, for certain hormones (like progesterone), there are conversion factors that need to be used while trying to change from one unit to another, right? Are there any such specifications for Canine c reactive protein?

Thanks again!

Shravani Bishnoi , you are only converting between prefixes of the metric/SI system; thus, the conversion between ng/mL and mg/L is only that straightforward.

You might be confusing this question with converting between grams, moles and daltons, which will really require specific conversion factors.

Canine CRP has a molecular weight that is approximated between ~100 kDa and ~156 kDa, with two studies estimating it at 115 kDa [1]. 1 Da = 1 g/mol, so 115 kDa translates to 115000 g/mol. Converting ng/mL to mg/dL to nmol/L, therefore, means you have to multiply your initial value in ng/mL by 0.0001 (or divide it by 10000) to get the value in mg/dL, then divide the value in mg/dL by 0.0115. However, this is irrelevant to your query since the conversion you are looking for is within the bounds of prefix-grams and prefix-liters.

Aedrian Abrilla Thanks so much for explaining this so clearly! I appreciate your help. :)
