How to use it

  1. Enter total volume in liters.
  2. Input the mix ratio (A parts per 1 part B).
  3. Click Calculate.
  4. Read the separate A and B volumes.

What it does

The Mix Calculator takes your total volume and a ratio expressed as parts of component A per one part of component B and instantly tells you how many liters of each component you need.

Why it matters

Knowing the exact split prevents over‑mixing, saves money, and ensures the final product meets performance specifications. Whether you’re preparing concrete, a chemical solution, or a large‑batch beverage, the correct proportions are critical.

How to read the results

The first number is the volume of Component A, the second is Component B. Both add up to the total volume you entered (ignoring any waste allowance you might add later). Use the values as‑is or round to a convenient measuring increment.

Pro tips

  • Add a 5% waste allowance to each volume for spillage.
  • Round up to the nearest 0.1 L for easier measuring.
  • Order component B first; it determines the base quantity.
  • Double‑check the ratio format (A per 1 B) to avoid swapping parts.

Real-life examples

  • A contractor mixing concrete where cement (A) and sand (B) must follow a specific ratio.
  • A bartender preparing a large batch of cocktail that requires 8 A : 1 B.
  • A DIY gardener blending fertilizer concentrate (A) with water (B) for a garden bed.

Case study

Sam, a small‑scale roofer, needed 120 L of roofing sealant at a 15 A : 1 B ratio. Using the calculator, he instantly saw he required 115.38 L of component A and 7.69 L of component B, ordered the exact amounts, and finished the job without leftover mix.

Frequently asked questions

What does the mix ratio A:B mean?
It means A parts for every 1 part B.
Can I use milliliters instead of liters?
Yes, just enter the total volume in the same unit; the calculator keeps the proportion.
Why does the calculator show decimal volumes?
Because most ratios don’t split evenly into whole liters; you can round after the calculation.
Is there a limit to the total volume I can enter?
No, you can input any positive number; the calculation scales proportionally.
Do I need to account for waste?
Add a small percentage manually; the tool gives the exact mix before waste.
