Tirzepatide Units Conversion Chart: mg to Units Reference

How to use this chart: Find your vial concentration in the left column, then find your weekly dose across the top. The cell shows how many units to draw in an insulin syringe.

💡 The formula is simple: Units = (Dose in mg ÷ Concentration in mg/mL) × 100. Or use our interactive dose calculator which does this automatically.

Understanding the Math

Insulin syringes are marked in units where 100 units = 1mL. So to convert:

  1. Divide your dose (mg) by your concentration (mg/mL) to get mL
  2. Multiply mL by 100 to get units on the syringe

Example: 5mg dose, 5mg/mL concentration → 5 ÷ 5 = 1mL → 1 × 100 = 100 units

Which Syringe to Use
