Calculating Correct Water
Temperature
The following is an example of how to calculate
the correct water temperature to use. You must
use your own room temperature, dry mix
temperature, desired batter temperature, and, if
you are making yeast-raised donuts, estimated
temperature increase during mixing.

Ratios of Plunger Sizes to
Donut Weights
The weights given are for donuts without icings
or other toppings. They are provided for
reference only, as weights vary according to the
density of the batter.
Plunger Size Donut Weight per
Dozen
1” 5-8 oz/142-227 g
1 7/16” 10-17 oz/283-482 g
1 9/16” 14-21 oz/397-595 g
1 13/16” 19-23 oz/539-652 g
Temperature Conversion
To convert temperatures from Fahrenheit to
Celsius, subtract 32 from °F and divide the result
by 1.8. For example, 212°F-32/1.8 = 100°C.
To convert temperatures from Celsius to
Fahrenheit, multiply °C by 1.8 and add 32 to the
result. For example, (100°C x 1.8) + 32 = 212°F.
