This donut calculator takes the figures you already have and applies the relationship behind donut calculations for you, giving time to burn these donuts and calories eaten from met, calories per donut, i ate…, weight and one way.
What Is the Donut Calculator?
The donut calculator sorts out the arithmetic of met, calories per donut, i ate..., weight and one way so that you can concentrate on the cooking rather than the maths.
It gives you time to burn these donuts and calories eaten, which is usually the number you actually need to measure out before you start.
How to Use the Donut
Fill in what you have and read off time to burn these donuts and calories eaten. If you are scaling a recipe up or down, work out the multiplier first and then multiply every quantity by it, including the ones that are not in this calculator.
Weigh rather than scoop wherever the recipe allows it. Volume measurements drift with how tightly an ingredient is packed, and that is where most recipe inconsistencies start.
Getting Consistent Results
Kitchen temperature, ingredient temperature and how long you mix all change the outcome. The calculator handles the quantities; the technique is still down to you.
If a result looks unfamiliar, check your units before you change the quantities. A factor of a hundred or a thousand is the usual culprit.
A Worked Example
Working through an example, with met set to 10, calories per donut set to 5, i ate... set to 2, the calculator returns calories eaten of 10, and time to burn these donuts of 0.01. Substitute your own figures and the same steps produce the same kind of answer.
Frequently Asked Questions
What do I need to work out time to burn these donuts?
Enter met, calories per donut, i ate..., weight and one way. The calculator then works through the relationship and reports time to burn these donuts and calories eaten.
What does the donut actually calculate?
It takes met, calories per donut, i ate..., weight and one way and converts them into time to burn these donuts and calories eaten using the standard relationship for this problem. Each step is applied in turn, so every output is traceable back to the numbers you typed in.
How should I enter met?
Use the value you actually have, in the unit shown next to the field. Enter every value in the same unit system. The calculator assumes the figures you supply are consistent, so it cannot correct a mistake that happens before the calculation starts.
Is the answer exact?
It is as exact as the formula and the inputs allow. The method itself is the standard one for this problem, so the only sources of error are the figures you enter and the precision you ask for.
Does anything you type get stored?
No. The whole calculation runs inside your browser, and nothing you enter is uploaded, logged or sent anywhere.
