Enter a target amount to see your result.

Concentration— mg/mL

Calculated values are approximate. Sample count is theoretical and excludes measurement loss.

Understand the measurement

Concentration = vial amount ÷ final solution volume. Sample volume = target amount ÷ concentration. For U-100, multiply the volume in mL by 100 to get the scale reading.

Use the final solution volume. If entering liquid added, the calculation assumes it equals the final volume. For blends, the result refers to the total blend amount you enter.

For laboratory research only

This tool performs unit conversions; it does not select a dose, solvent, or research protocol. U-100 scale units measure volume and are not peptide activity units (IU). Do not enter an IU-labelled strength, such as HGH, as mg.

1 mg = 1,000 mcg · 1 U-100 scale unit = 0.01 mL
