Mixing Ratio Calculator
The Mixing Ratio Calculator determines exact amounts of each component when combining materials at a specified ratio. Enter a mixing ratio like 3:1:1 and total volume to get precise measurements — perfect for paint mixing, epoxy, concrete, resin, and chemical solutions.

What is a Mixing Ratio?
A mixing ratio specifies the proportional amounts of each component in a mixture. A 3:1 epoxy ratio means 3 parts resin to 1 part hardener by volume or weight. Accurate mixing ratios are critical — incorrect proportions can cause epoxy that never cures, paint that won't dry, or concrete that crumbles.
Mixing ratios appear in automotive paint (4:1:1 base:reducer:hardener), construction (1:2:3 cement:sand:gravel), bartending (2:1 spirit:mixer), and chemical manufacturing. Some ratios are by volume and others by weight — always check which unit the ratio references.
Verwendete Formeln & Gleichungen
Dieser Mixing Ratio Calculator verwendet 5 Kern-Gleichungen:
1 Component Amount ▼
For 3:1 ratio and 1 gallon total: Part A = 1 gal × (3/4) = 0.75 gal; Part B = 1 gal × (1/4) = 0.25 gal.
2 Total from Component ▼
If Part A is 600ml and ratio is 3:1: Total = 600 × (4/3) = 800ml.
3 Three-Part Mix ▼
For 4:1:1 and 3 liters: Part A = 3 × (4/6) = 2L; Parts B&C = 0.5L each.

Häufig gestellte Fragen
How do I calculate a mixing ratio? ▼
Divide each component amount by the smallest amount. If you mix 750ml of A with 250ml of B: divide both by 250 to get 3:1. This simplification gives you the ratio in its simplest form.
Is mixing ratio by weight or volume? ▼
It depends on the product. Epoxy and paint ratios are usually by volume. Concrete and food ratios may be by weight. Always check the product label — mixing by the wrong unit can cause failures.
What happens if I mix epoxy at the wrong ratio? ▼
Incorrect ratios cause incomplete curing. Too much resin leaves a sticky, soft surface. Too much hardener creates a brittle, yellowed result. Most epoxies have very little tolerance — stay within 5% of the specified ratio.
How do I convert a mixing ratio to percentage? ▼
Divide each part by the total. A 3:1 ratio = 3/4 = 75% Part A and 1/4 = 25% Part B. A 5:3:2 ratio = 50% + 30% + 20%.
Can I scale a mixing ratio up or down? ▼
Yes. Multiply all parts by the same factor. If 3:1 uses 300ml + 100ml, doubling gives 600ml + 200ml. The ratio stays 3:1 regardless of total volume.
