Peptide Dose Converter

Convert any amount between milligrams, micrograms, millilitres and U-100 insulin syringe units. Set your concentration once and the conversions update as you type, with every formula shown below.

2 · Convert mass ⇄ mL ⇄ U-100 units (needs concentration)

= 2500 mcg/mL · 1 unit = 0.01 mL = 25 mcg

The conversion formulas

1 mg = 1000 mcg  |  1 mcg = 0.001 mg
Volume (mL) = Mass (mg) ÷ Concentration (mg/mL)
Units (U-100) = Volume (mL) × 100
Mass (mg) = Volume (mL) × Concentration (mg/mL)  |  mL = Units ÷ 100

The unit-to-mL bridge. A U-100 insulin syringe simply divides a 1 mL barrel into 100 equal marks, so 1 unit = 0.01 mL. That single fact lets you move freely between the syringe scale and real volume; the concentration then connects volume to mass. No insulin is involved — the "units" are just fine gradations.
