mg → syringe units converter
The conversion is (dose ÷ concentration) × 100 for a U-100 syringe. The trap is that the same milligram dose is a different mark on the syringe at every concentration.
mg → syringe units converter
U-100 syringe. Formula: (dose ÷ concentration) × 100.
Check the concentration printed on the vial you are actually holding. The same dose in milligrams is a completely different mark on the syringe at a different concentration. If the number here does not match what your prescriber told you, trust your prescriber.

Sources and last review
Every dosing figure on this page is transcribed from an FDA-approved label and links back to it. Conversions are arithmetic you can repeat by hand. Nothing here is reviewed by a clinician, and this site does not employ one — which is exactly why what I do publish stays traceable to its source.
