Scale units describe volume, not peptide potency or IU.

Understand the calculation.

For example, 5 mg in a final volume of 2 mL gives 2.5 mg/mL. A 250 µg sample occupies 0.1 mL: 10 units on a U-100 scale.

How does solution volume affect the result?

A larger final volume lowers concentration, so the same sample amount occupies more liquid. Enter the actual final volume.

How are syringe units calculated?

Sample volume = sample mass ÷ concentration. Multiply milliliters by 100 for a U-100 scale.

Does syringe capacity change the calculation?

No. Capacity changes the displayed range, not the conversion. Check your syringe’s actual markings.

Can the calculator choose a diluent or storage period?

No. Follow product-specific documentation for compatibility, preparation and storage.

Which mass should I enter?

Use the documented material amount. Purity percentage and net content are different; no assay correction is applied.

For laboratory and educational calculations only. This tool does not determine an administration dose or treatment plan. Independently verify inputs and results.
