Chemical dilution calculator.

Work out concentrate-to-water mixes for any container, any ratio, any unit system. Three input modes: make a solution, see how far your concentrate goes, or back-solve the ratio from amounts you already have.

Updates as you type · metric, US gallons and imperial gallons supported
1 Mode
Units iPick the unit system you work in. US gallon (3.785 L) and Imperial gallon (4.546 L) are different — treat them as separate.
What do you want to work out? iPick the mode that matches what you know. Each mode asks for two of the three numbers (dilution, concentrate, total volume) and tells you the third.
2 Your numbers
Dilution rate iPick the form you have. Ratios use the parts convention (1:50 = 1 part concentrate to 50 parts water). Percentage is the concentrate as a fraction of the total finished solution.
1 : %
Percentage of the total finished solution. Triple7 DSP defaults: 1.4% establishment, 2.0% build, 1.0% maintenance.
Total volume you want to make iThe final amount of finished solution you want. Tap a container preset or type any number.
Dilution rate iThe dilution this concentrate will be used at.
1 : %
Percentage of the total finished solution.
Concentrate you have iThe amount of undiluted product you have on hand. We'll work out how much finished solution that will make.
Concentrate amount iThe amount of undiluted product you used (or plan to use).
Total finished solution iThe amount of finished solution that concentrate is mixed into.
Include concentrate cost (optional) iEnter what you pay for the concentrate per litre (or per gallon in US/Imperial mode). We'll work out the cost per litre of finished solution and the total cost of this batch.

How the maths works

All three input forms describe the same physical thing — how much concentrate ends up in the finished solution — just expressed differently. The calculator converts everything to a single internal fraction (concentrate ÷ total solution), then back out into the form you asked for.

  • Ratio (1:X) — parts convention. 1 part concentrate to X parts water. Total parts = 1 + X. A ratio of 1:50 means concentrate is 1/51 = 1.96% of the finished solution, not 2%. The numbers are close at high dilutions but diverge at low ones.
  • Percentage (%) — the concentrate as a fraction of the total finished solution. This is the form most modern product labels use (including Triple7 Dust Suppression Plus). 2% means 2 parts concentrate per 100 parts of finished solution.
  • Per unit — in metric, mL of concentrate per L of finished solution. In US, fl oz per US gallon (128 fl oz / gal). In Imperial, fl oz per Imperial gallon (160 fl oz / gal). US and Imperial gallons differ by ~20% — the calculator treats them as separate units.

A note on accuracy

  • The calculator is a working aid. The authoritative dilution for any specific Envirofluid product is whatever appears on the product label, the SDS, and the application guidance for your use case.
  • For very high dilutions (1:1000 and beyond), concentrate volumes can fall below 1 mL in small containers — consider mixing a larger batch and decanting for accuracy.
  • For very strong concentrations (above ~30%) most cleaning chemistries are not designed for use at that strength — check the product label.
