How It Works
This calculator works in 4 steps.
Enter the label ratio
Type the ratio or the amount per gallon or liter from the label.
Confirm the convention
Select concentrate-to-water (most cleaning labels) or concentrate-to-total.
Enter the container size
Type the bottle, bucket, or tank volume.
Read the amounts
The calculator returns concentrate and water in metric and US units.
The Formula
The formula divides the container volume by the total parts of the ratio.
V_conc = V_container / (X + 1)V_water = V_container − V_concV_conc = (oz per gal) × gallons- X:
- Water parts per 1 part concentrate
- V_container:
- Total volume of the mix
A 1:32 ratio in a 1 US gal (3.785 L) bucket needs 3,785 / 33 = 114.7 mL (3.88 fl oz) of concentrate.
Conversion Table
The conversion table gives concentrate per liter and per US gallon of mix for 7 label ratios.
| Ratio (conc:water) | Per 1 L of mix | Per 1 US gal (fl oz) | Per 1 US gal (mL) |
|---|---|---|---|
| 1:4 | 200 mL | 25.6 fl oz | 757.1 mL |
| 1:10 | 90.91 mL | 11.64 fl oz | 344.1 mL |
| 1:16 | 58.82 mL | 7.529 fl oz | 222.7 mL |
| 1:20 | 47.62 mL | 6.095 fl oz | 180.3 mL |
| 1:32 | 30.3 mL | 3.879 fl oz | 114.7 mL |
| 1:64 | 15.38 mL | 1.969 fl oz | 58.24 mL |
| 1:128 | 7.752 mL | 0.9922 fl oz | 29.34 mL |
What Is the Cleaning Product Dilution Calculator?
The Cleaning Product Dilution Calculator is a tool that scales a manufacturer-specified mixing ratio, such as 1:32 or 2 oz per gallon, to any container size. The calculator returns concentrate and water amounts in mL, L, US fl oz, and US gallons.
Cleaning labels state ratios for different jobs: a general-purpose cleaner can list 1:64 for light soil and 1:16 for heavy soil. The calculator takes the ratio exactly as the label states it and confirms whether the label means parts of water or parts of total. Product labels take priority over any generic ratio.
Common Uses
There are 5 main uses of this calculator.
Janitorial work
Cleaning crews mix general-purpose cleaners for each task.
Commercial kitchens
Kitchen staff mix degreasers at label strength.
Vehicle washing
Detailers mix shampoos and all-purpose cleaners.
Floor care
Custodians mix neutral floor cleaners for autoscrubbers.
Cost control
Managers prevent overuse of concentrate.
