How many mcg are in 1 mg?

1 milligram = 1,000 micrograms.

How do I convert mg to insulin units?

Volume (mL) = mg ÷ concentration (mg/mL). Units = mL × syringe scale (100 for U-100, 50 for U-50, 40 for U-40). Enter the dose and concentration above and you'll see all three.

How many IU is 1 mg of HGH?

Approximately 3 IU per mg of human growth hormone (the WHO international standard). 1 mg ≈ 3 IU; 5 mg ≈ 15 IU. Different peptides use different mg/IU ratios. Pick the right preset above.

How many IU is 1 mg of hCG?

Approximately 6,000 IU per mg of hCG. So a 5,000 IU dose ≈ 0.83 mg.
