Use final volume
The amount of liquid added is not always the final solution volume. Follow the product’s preparation instructions; this calculator does not choose a diluent or mixing method.

A few details that matter.
Check the scale
On a U-100 syringe, 100 scale marks correspond to 1 mL. Other syringe types use different scales. See BD’s syringe capacity reference.
Confirm before using
The math cannot establish a safe dose, product quality, suitability, stability, or sterility. Ask your pharmacist to confirm the concentration and how to measure your prescribed amount.
