希釈倍率計算機

初期体積と最終体積から希釈倍率(DF = V2/V1)を計算します。

はじめに

Dilution Factor Calculator — Calculate the dilution factor (DF = V2/V1) between an initial and final volume. Enter V1 (mL or L), V2 (final volume) to get an instant, accurate result.

計算式

Dilution factor = V₂ / V₁ (final volume divided by initial volume), expressed as a ratio 1:DF.

ステップごとの説明

  1. Enter the V1 (mL or L).
  2. Enter the V2 (final volume).
  3. Click Calculate to see your result instantly.

実例

Example: With V1 (mL or L) = 1, V2 (final volume) = 5, the Dilution Factor Calculator gives Dilution Factor: 5, Ratio: 1:5.

よくある質問

What does a dilution factor of 1:10 mean?
It means the original solution was diluted to 10 times its starting volume — one part stock solution plus nine parts diluent.
How is dilution factor related to concentration?
Since C₁V₁ = C₂V₂, the dilution factor V₂/V₁ equals C₁/C₂ — the concentration drops by the same factor the volume increases.
What inputs does the Dilution Factor Calculator need?
You'll need to provide: V1 (mL or L), V2 (final volume). All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the Dilution Factor Calculator?
The Dilution Factor Calculator applies the formula exactly as calculated — Dilution factor = V₂ / V₁ (final volume divided by initial volume), expressed as a ratio 1:DF. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Dilution Factor Calculator free to use?
Yes, the Dilution Factor Calculator is completely free, requires no signup, and runs instantly in your browser.

希釈倍率計算機について

The Dilution Factor Calculator uses a real, verifiable formula — Dilution factor = V₂ / V₁ (final volume divided by initial volume), expressed as a ratio 1:DF. — so results are accurate every time, not an approximation.
