Add 3.33 L Resin and 1.67 L Hardener to make 5 L.

How to mix 2:1 in 5 liters

This calculator treats 2:1 as resin-to-hardener by volume and divides the 5 liters total accordingly. Use the manufacturer’s separate by-weight ratio when it provides one.

  1. Confirm that the exact product specifies 2:1 resin:hardener by volume. A ratio by weight can be different.
  2. Measure the displayed component amounts separately: 3.333 L Resin, 1.667 L Hardener.
  3. Combine and mix using the manufacturer’s timing, temperature, and safety instructions.

Accuracy tips

Resin and hardener densities can differ, so a volume ratio must not be assumed to be the same numeric ratio by weight. Use the exact product technical data.

How this is calculated

For a ratio of a:b, each part is a/(a+b) and b/(a+b) of the total. PPM mode uses 1 ppm ≈ 1 mg/L for aqueous solutions. Show gram targets to convert those calculated volumes using the densities you provide; the ratio itself remains volume-based.
