Multiply by 1000, so 50 mcg

100 mcgs=how many mg's

0.025 milliliters is the same as:

How do I dilute 25 micrograms per ml to 2.5 grams per ml

You don't. 25 µg/mL = 0.000025 g/mL. It is too dilute by 100000-fold

1. Ordered: 300mcg
On hand: 0.15 mg tablets
• How many tablets do you need?

You need to understand the relationship between micrograms and milligrams
1000 mcg (1000 µg) = 1 mg

So each 0.15 mg tablet is 150 mcg.

I have two values that I am trying to compare.

I have 6.0 mg/kg and need to compare it to 5 mg/L. Is the later less than the former or visa versa?

If the solutions are dilute aqueous solutions then the density is about 1 kg/L, and the 6 mg/kg is the larger value. Otherwise, you need to make a density correction. If you know the density of the first mixture, you can multiply by it to convert to mg/L and compare. Alternatively if you know the density of the 2nd mixture, you can divide by it to convert to mg/kg and compare. Without one of the densities (or at least an approximation) you can't really say.

5mg and 5mcg.are they same thing?
