How It Works
This calculator works in 4 steps.
Enter the water fill volume
Type gallons, quarts, or liters of water in the bucket.
Enter the label rate
Type the per-gallon or ratio instruction from the product label.
Add the dispenser pump volume
Type the volume per pump stroke, if a pump dispenser is used.
Read the amount
The calculator returns concentrate in fl oz, mL, cups, and pump strokes.
The Formula
The formula multiplies the label rate per gallon by the gallons of water.
V_conc = rate (oz/gal) × gallonsStrokes = V_conc / V_pump1 cup = 8 fl oz = 236.6 mL- rate:
- Label amount per US gallon
- V_pump:
- Dispenser volume per stroke
A 4 gallon fill at 1 fl oz per gallon needs 4 fl oz (118.3 mL, 1/2 cup) of floor cleaner.
Conversion Table
The conversion table gives the concentrate amount for 6 bucket fills and label rates.
| Water in bucket | Label rate | Concentrate (fl oz) | Concentrate (mL) | Concentrate (cups) |
|---|---|---|---|---|
| 2 US gal (7.57 L) | 2 fl oz/gal | 4 fl oz | 118.3 mL | 0.5 cups |
| 3 US gal (11.36 L) | 2 fl oz/gal | 6 fl oz | 177.4 mL | 0.75 cups |
| 4 US gal (15.14 L) | 1 fl oz/gal | 4 fl oz | 118.3 mL | 0.5 cups |
| 5 US gal (18.93 L) | 0.5 fl oz/gal | 2.5 fl oz | 73.93 mL | 0.3125 cups |
| 6 US gal (22.71 L) | 2 fl oz/gal | 12 fl oz | 354.9 mL | 1.5 cups |
| 8 US gal (30.28 L) | 1 fl oz/gal | 8 fl oz | 236.6 mL | 1 cups |
What Is the Mop Bucket Dilution Calculator?
The Mop Bucket Dilution Calculator is a tool that scales a product's per-gallon instruction to the water volume in a mop bucket. The user enters the fill volume, not the bucket's rated size, since most buckets are filled to a line below the rim.
Commercial mop buckets hold 26 to 44 quarts (6.5 to 11 gallons), and household buckets hold 2 to 4 gallons. The calculator returns concentrate in fl oz, mL, and cups, so the user can measure with whatever is at hand. A portion-control dispenser gives repeatable doses, and the calculator shows how many pumps match the dose when the pump volume is entered.
