Mixing Ratio Converter

Q: Why is the ratio definition different for w/v?

% w/v is mass per solution volume. We define the ratio accordingly: solute mass : solution volume (e.g., 5:100 → 5% w/v).

Q: Can I enter solute and solvent without total?

Yes—for w/w and v/v. We compute total, percent, and a simplified ratio.

Q: Do I need to match units?

No. The tool converts g↔mg and mL↔L automatically.

Convert between ratio and percent and compute component amounts for w/w, w/v, and v/v mixtures. Enter a ratio or percent, plus any amount (total, solute, or solvent) and we’ll solve the rest, show steps, and visualize with a mini bar chart and a ratio gauge.

Background

For a two-component mixture, let “solute” be the part of interest and “solvent” the remainder.
Percent is the solute fraction × 100.
Ratio depends on mode:
• w/w or v/v: ratio = solute : solvent (e.g., 1:9 → 10% solute).
• w/v: ratio = solute mass : solution volume (e.g., 5:100 → 5% w/v).
Units auto-convert (g↔mg, mL↔L).

Mixture type:

Ratio meaning changes by mode (see Background).

Ratio (parts):

w/w & v/v → solute : solvent • w/v → solute mass : solution volume

Leave blank if you prefer to enter percent.

Percent (%):

(0–100). Leave blank if using ratio.

Amounts (any one is enough with ratio/percent):

w/v uses solute mass and solution volume; “solvent” is not used in w/v math.

How to use this converter

Pick the mode (w/w, w/v, v/v). Note the ratio definition in the hint.
Enter either ratio or percent to define mixture strength.
Add any amount (total, solute, solvent) — we compute the rest and show steps.
Units auto-convert: g↔mg and mL↔L.
