Conversion Tables

## Diluted Cost Per Gallon

Divide dilution into cost per gallon.

Example: (1:128 dilution selling at \$13.40 per gallon)
\$13.40 ÷ 129 = .1038 -or- 10.4¢ per diluted gallon

## Dilution Ratio

Divide ounces per gallon into 128.

Example:
(4 ounces per gallon dilution)
128 ÷ 4 = 32

1:32 ratio

## Ounces Per Gallon

​Divide dilution ratio into 128.

Example:
(1:32 dilution)
128 ÷ 32 = 4

4 ounces per gallon

## Temperature Conversion

°C = 5/9 x (°F – 32)

Example:
70°F = 5/9 x 70 – 32 = 21°C

°F = 9/5 x (°C) + 32

Example:
25°C = 9/5 x 25 + 32 = 77°F

## Metric Volume Equivalents

1 fluid ounce = 30 milliliters

8 ounces (1 cup) = 237 milliliters

16 ounces (1 pint) = 473 milliliters32 ounces (1 quart) =946 milliliters

64 ounces (½ gallon) = 1892 milliliters -or- 1.9 liters

128 ounces (1 gallon) = 3785 milliliters -or- 3.8 liters

## Hard Water Measurements

Hard water contains ions of magnesium and calcium.
1 grain hard water = 18 ppm hard water

Example:
450 PPM hard water = 25 grain
(450 ÷ 18 = 25)

## Active Parts Per Million

Commonly used for disinfectants.
Step 1: Add together active ingredients on label.
Step 2: Multiply by 10,000.
Step 3: Divide the result of Step 2 by the dilution rate.

Example:
Using Quat 44-HBV (#2318) (1:64 dilution)
1. 2.25% + 2.25% = 4.5% active
2. 10,000 x 4.5 = 45,000
3. 45,000 ÷ 65 = 692 PPM Active Quat
