Syringe Unit Converter
Convert between syringe volume graduations, millilitres, milligrams and micrograms at a given solution concentration.
One reading, every scale.
Convert between micrograms, milligrams, millilitres and U-100 insulin syringe units for any solution. Useful for verifying a draw volume before it leaves the bench.
Example reading
2,500 µg/mL → 250 µg = 0.1 mL = 10 units

How it works
The conversions
Fixed ratios
1 mg = 1,000 µg · 1 mL = 100 units (U-100)
Mass and volume meet through concentration: µg = µg/mL × mL, and units = mL × 100.

Reference
Units to milligrams
U-100 reading converted to volume and to delivered mass at the three concentrations most reconstitution protocols land on. Multiply the volume by your own mg/mL if it differs.
| Units | Volume | 2.5 mg/mL | 5 mg/mL | 10 mg/mL |
|---|---|---|---|---|
| 5 u | 0.05 mL | 0.13 mg | 0.25 mg | 0.50 mg |
| 10 u | 0.10 mL | 0.25 mg | 0.50 mg | 1.00 mg |
| 15 u | 0.15 mL | 0.38 mg | 0.75 mg | 1.50 mg |
| 20 u | 0.20 mL | 0.50 mg | 1.00 mg | 2.00 mg |
| 25 u | 0.25 mL | 0.63 mg | 1.25 mg | 2.50 mg |
| 30 u | 0.30 mL | 0.75 mg | 1.50 mg | 3.00 mg |
| 50 u | 0.50 mL | 1.25 mg | 2.50 mg | 5.00 mg |
| 100 u | 1.00 mL | 2.50 mg | 5.00 mg | 10.00 mg |
Rounded to two decimals. Assumes a U-100 syringe; for U-40 or U-500 divide by that calibration instead.
