2:1 in 1 gallon

Precise mix & dilution math. Toggle by volume/weight, edit density, copy-to-label.

Exact amounts (pre-calculated)

  • Part A85.33 oz by volume2826.4 g
  • Part B42.67 oz by volume1198.7 g

Add 85.33 oz Part A, 42.67 oz Part B; fill to 1 gal.

How to mix 2:1 in 1 gallon

This calculator preloads a 2:1 dilution inside a 1 gallon container. Confirm the total volume, then follow the product and water amounts surfaced above. Toggle the weight view if you prefer weighing by grams or need density adjustments for thicker concentrates.

  1. Note the exact product and carrier amounts in the "Exact amounts" card. That output updates instantly as you tweak totals or rounding.
  2. Pour the product part first so you can rinse residue with the larger carrier volume.
  3. Top up with water or solvent until you hit the target fill line, then gently invert or stir to homogenize the mix.

Accuracy tips

Need to batch multiple bottles? Duplicate this preset, change the container size, and use the "Copy label" line for fast relabelling. When mixing by weight, enter actual densities so the gram figures hit your process tolerances.

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. Switch to "Mix by weight" to convert those fractions into gram targets using your provided densities.
