Learning how to count calories can help you plan a healthy diet. Although most food labels list the number of calories in their products, they usually don't identify the calorie of each ingredient that makes up the product. By understanding the difference between calories and grams and learning the conversion rate, you can easily calculate the amount of calories in a specific nutrient.

Steps

Method 1 of 3: Converting Grams of Fat to Calories

Convert Grams to Calories Step 1

Step 1. Check the nutritional values ​​on the label

Most labels list how many grams of fat are in each serving of that particular product. This is how you calculate calories.

Convert Grams to Calories Step 2

Step 2. Multiply the grams of fat by 9

Each gram of fat contains 9 calories. To find out how many calories there are in a fat content, just multiply the grams of fat by 9.

For example, if the product contains 10 grams of fat, multiply 10 grams of fat by 9 calories for a total of 90 calories. This is the total calories in one gram of fat

Convert Grams to Calories Step 3

Step 3. Calculate the total amount of calories in the entire product

To find the total calories and fat content of a particular product, multiply the original number received earlier by the number of servings in that package.

If the label says the package serves three servings, multiply 90 by 3, for a total of 270 calories

Method 2 of 3: Converting Grams of Carbohydrates and Proteins into Calories

Convert Grams to Calories Step 4

Step 1. Know that carbohydrate is an organic component

Carbohydrates are made up of carbon, hydrogen and oxygen. They always contain calories (4 per gram), but these don't automatically mean there are carbohydrates, as they are in other macronutrients.

Convert Grams to Calories Step 5

Step 2. Check the nutritional values ​​on the label

You will see how many grams of carbohydrate there are per serving. Carbohydrates have 4 calories per gram. Multiply their number by 4 to calculate the existing total calories.

For example, if a product has 9 grams of carbohydrates, multiply 9 by 4 to get a total of 36 calories. You have to multiply it by 4 because there are 4 calories in every gram of carbohydrate

Convert Grams to Calories Step 6

Step 3. Find the total number of calories coming from protein

Proteins are also listed on product labels. Like carbohydrates, each gram of protein contains 4 calories. Again, multiply the number of grams of protein by 4 to calculate total calories.

Method 3 of 3: Understand the grams vs. calories ratio

Convert Grams to Calories Step 7

Step 1. Understand the difference between grams and calories

A gram is a metric unit of mass that equals one thousandth of a kilogram. A calorie is a unit of energy that people receive through food. One kilogram of body fat equals about 7,000 calories.

Gram and calorie are different units of measurement that cannot be converted into each other

Convert Grams to Calories Step 8

Step 2. Find the energy unit in which you want to measure calories

The amount of calories per gram of a food depends on the level of macronutrients. The human body can obtain energy (from calories) through three macronutrients: carbohydrates, fats and proteins.

You cannot weigh a food and convert its grams to calories. You need to know how many calories are in a specific type of macronutrient to calculate the total calories in the food

Convert Grams to Calories Step 9

Step 3. Multiply the number of grams by the conversion number

Look at the label of the food whose calorie count you would like to calculate. Each nutrient will be listed in grams. Once you find the nutrient you want, multiply that number by the number of calories that particular nutrient has in each gram.
