How to use this calculator
- Enter the dilution as 1:N (just the N) and the total mixture you want.
- Read the concentrate and water amounts.
How it works
For 1:N, concentrate = total ÷ (1 + N) and the rest is water. So 1:10 of 1000 mL is ~91 mL concentrate.
Worked example
1:10, 1000 mL total. ≈ 91 mL concentrate, 909 mL water.
Common mistakes
- Reading 1:10 as 10% — it's 1 part in 11, about 9.1%.
- Mixing units — keep concentrate, water and total in the same unit.
Frequently asked questions
