Calorie to Gram Conversion Table

If your are speaking about nutritional energy (calories ) obtained from food, The formula is Energy (in Kcal) = 4x (Proteins and carbohydrates mass in grams) + 9 x mass of fat in grams.

How to Convert Calories to Ounces. To convert a calorie measurement to an ounce measurement, multiply the weight by the conversion ratio. The weight in ounces is equal to the calories multiplied by 0.004571.

Multiply Grams by 4

1. Multiply Grams by 4.
2. If you’re tracking your carbohydrate intake by the gram, multiply that number by 4 to convert it into kilocalories/gram.
3. So, if you consumed 275 grams of carbohydrates today, that would be:
4. 275 grams × 4 kilocalories/gram = 1100 kilocalories.

The calorie content is often given in kcals, which is short for kilocalories, and also in kJ, which is short for kilojoules. A kilocalorie is another word for what’s commonly called a calorie, so 1,000 calories will be written as 1,000kcals.

Here’s your equation: MET value multiplied by weight in kilograms tells you calories burned per hour (MET*weight in kg=calories/hour). If you only want to know how many calories you burned in a half hour, divide that number by two. If you want to know about 15 minutes, divide that number by four.

Scientifically, 1 kilocalorie (1000 calories or 1 kcal) means the energy it takes to raise the temperature of 1kg of water by 1°C. By definition, Calories are units of energy so small that a tiny piece of food can provide thousands of them. Simply, 1 Calorie is equal to 1 kilocalorie.

A gram of fat has about 9 calories, while a gram of carbohydrate or protein has about 4 calories. In other words, you could eat twice as much carbohydrates or proteins as fat for the same amount of calories.
