How it is calculated
Concentration
Vial mass ÷ final solution volume.
Required volume
Specified target mass ÷ concentration.
U-100 volume equivalent
Volume in mL × 100 scale markings.
Peptide calculator: mg, mcg and mL explained
A reconstitution or concentration calculation needs the amount of material in one vial and the final solution volume. The calculator above uses the values you enter; it does not select an administration dose.
Concentration
10 mg ÷ 2 mL = 5 mg/mL. Enter mass for one vial, not a full kit.
Micrograms
1 mg = 1,000 mcg. Check the unit selector before entering a target amount.
Target volume
A specified 1 mg laboratory aliquot from 5 mg/mL corresponds to 0.2 mL (200 µL).
Does the calculator choose a dose or solvent?
No. It performs arithmetic on supplied mass and volume values. Compatibility, handling, sterility and any administration decision are outside its scope.
Can it convert IU to mg?
No. There is no general IU-to-mg conversion in this tool. It is a mass-and-volume calculator, not an activity-unit converter.
Why is there a U-100 marking result?
The illustrated scale uses 100 markings per mL. Markings describe volume on that specific scale, not peptide activity or a recommended amount. Read the scale warning and never measure from the screen.
