Concentrate dilution calculator
Use only a label dose expressed in mL of concentrate per litre of water. Enter the final mixture volume in litres, including the concentrate.
Enter your values, then calculate.
Method and limitations
For dose d (mL/L of water) and final volume V (L): water = V ÷ (1 + d/1000); concentrate = d × water, in mL. Volumes are assumed additive. This does not apply to a dose per litre of final mixture, percentages or mass-based products. No dose is recommended. The product label takes precedence over this arithmetic estimate. NIST Appendix C: 1 L = 1000 mL.
