How many units is 2.5 mg?

Units (U-100) = 2.5 mg ÷ concentration (mg/mL) × 100. At 5 mg/mL (10 mg in 2 mL) 2.5 mg = 0.5 mL = 50 units; at 10 mg/mL it is 25 units; at 2.5 mg/mL it is 100 units (a full 1 mL syringe). Use the table or the calculator for your vial.

The math

concentration = vial mg ÷ water mL
units (U-100) = (2.5 ÷ concentration) × 100
Example: 2.5 ÷ 5 × 100 = 50 units
