Fat Percentage Calculator
One gram of fat has 9 calories. If you know the number of fat grams in a particular food, you can use the following formula to calculate the number of calories that come from fat in that food:
If you know the food’s total calories, you can use the following formula to calculate the percentage of calories from fat:
Create an application that allows the user to enter:
- The total number of calories for a food item
- The number of fat grams in that food item
The application should calculate and display:
- The number of calories from fat
- The percentage of calories that come from fat
Also, the application’s form should have a CheckBox that the user can check if he or she wants to know whether the food is considered low fat. (If the calories from fat are less than 30% of the total calories of the food, the food is considered low fat.)
Use the following test data to determine if the application is calculating properly:
Note: Make sure the number of calories and fat grams are not less than 0. Also, the number of calories from fat cannot be greater than the total number of calories. If that happens, display an error message indicating that either the calories or fat grams were incorrectly entered.

- Scenario You work for a small company that exports artisan chocolate. Although you measure your products in kilograms, you often get orders in both pounds and ounces. You have decided that rather than have to look up conversions all the time, you could use Python code to take inputs to make conversions between the different units of measurement. You will write three blocks of code. The first will convert kilograms to pounds and ounces. The second will convert pounds to kilograms and ounces. The third will convert ounces to kilograms and pounds. The conversions are as follows: 1 kilogram = 35.274 ounces 1 kilogram = 2.20462 pounds 1 pound = 0.453592 kilograms 1 pound = 16 ounces 1 ounce = 0.0283 kilograms 1 ounce = 0.0625 pounds For the purposes of this activity the template for a function has been provided.
