Worked example · arithmetic only, not a recommendation

Every result carries its trace.

The Formula Inspector lists each operation with the numbers the engine actually used. This example comes from the same engine as your own calculation: nothing is hard-coded.

Formula Inspector

Every line uses the same engine values as the result. ≈ marks display rounding only; full precision is retained.

  1. Normalize mass

    Vial mass in canonical units: 5,000 mcg

  2. Calculate concentration

    5,000 mcg ÷ 2 mL ≈ 2,500 mcg/mL

  3. Calculate target volume

    250 mcg ÷ 2,500 mcg/mL ≈ 0.1 mL

  4. Map to U-100 scale

    0.1 mL × 100 units/mL ≈ 10 units

The instrument library / 06

One engine. Six ways to measure.

Each tool answers a different question. All of them normalize mass to micrograms, keep volume in milliliters and share the same tested formulas.

Measurement tools

04 instruments
  1. Primary measurement

    Peptide Calculator

    Calculate concentration, target volume, U-100 marking and theoretical portions from your vial and target values.

    Needs
    Vial mass, liquid volume, target mass and the U-100 scale
    Returns
    Concentration, target volume, U-100 marking, amount per unit and theoretical portions
  2. Measurement

    Peptide Reconstitution Calculator

    Explore how a liquid volume you supply affects concentration and the equivalent volume of your target amount.

    Needs
    Vial mass, final liquid volume, target mass and the U-100 scale
    Returns
    Concentration for that liquid volume, target volume and U-100 marking
  3. Measurement

    Peptide Concentration Calculator

    Find mg/mL and mcg/mL from total mass and final volume. No target amount or syringe scale needed.

    Needs
    Vial mass and final liquid volume
    Returns
    Concentration in mg/mL and mcg/mL
  4. Measurement

    Reverse Peptide Calculator

    Convert an entered U-100 marking to volume and equivalent mass using your vial concentration.

    Needs
    Vial mass, liquid volume and a U-100 marking
    Returns
    Volume in mL, equivalent mass in mcg and mg, and concentration

Research horizon

Future research tools will join this library as they are developed. The six calculators above are available now.

Reference / fundamentals

Units and principles

The definitions every calculator relies on, and the rules the product follows.

Definitions

mg and mcg
Units of mass. 1 mg = 1,000 mcg. Calculations normalize every mass to mcg.
Concentration
Mass per volume: vial mass ÷ final liquid volume, in mcg/mL or mg/mL.
U-100
A syringe scale with 100 scale units per mL, so one unit is 0.01 mL. It measures volume, not mass.
Why concentration is required
A mass cannot be converted to scale units directly. Concentration links mass to volume, and volume maps to the scale.

Principles

  1. You supply every value. Forms start empty, and examples are labelled.
  2. One calculation engine. Every tool and every formula line uses the same functions.
  3. Local by default. Calculating sends nothing to a server. Share links are optional.
  4. No hidden multiplier. Every formula is public in the calculator methodology.
