gThe fixed factors
1 g = 1,000 mg = 1,000,000 mcg = 1,000,000,000 ng. These are pure mass conversions and never depend on concentration or a syringe.

How it works.
01
Type an amount
Enter a value and pick its unit: nanograms, micrograms, milligrams, or grams.
02
Read the other units
The other three units update instantly from the fixed 1000× factors between each step.
03
No concentration involved
This is pure mass arithmetic. It doesn't touch syringes, IU, or concentration; those depend on how a compound is mixed or measured.
FAQ.
How many mcg are in a mg?
1 mg = 1,000 mcg, and 1 mcg = 1,000 ng. 1 g = 1,000 mg. These factors are fixed and don't depend on the compound.
Does this convert to syringe units?
No. This is pure mass conversion. To turn micrograms into syringe units you need the concentration of your mixed vial: use the mcg → units converter for that.
