Download on theApp StoreAny mixing ratio, solved.
MixRatio does the arithmetic and the unit conversion you would otherwise do by hand, so the pour is right the first time. Enter a tank size and a ratio and it returns the exact amount of oil or concentrate to add, in the unit you actually measure with.
Four Calculators
- Fuel mix: two-stroke oil for any tank at 50:1, 40:1, 32:1, 25:1, or a custom ratio. See the oil for common tank sizes at a glance.
- Ratio: solve any two-part ratio from the total you want to make, the base you have, or the additive you have.
- Dilute: mix a concentrate to a target volume of solution, with the water and concentrate split out.
- Strength: enter a strength as a ratio, a percentage, or parts per million, and see all three at once.
Built for Real Work
- Metric and imperial: millilitres, fluid ounces, litres, and US gallons, switched anywhere.
- Save your common mixes: every saw, trimmer, cleaner, and feed you run, one tap away.
- Compare chart: see how strong each saved mix is, side by side.
- Recipe card: share any saved mix as a PDF with a mixing table for common batch sizes, or export your whole library as a CSV.
