Grams to Calories Converter (grams to kcal)

Are you tired of guessing the calorie content of your meals? Need to convert grams to calories? Quickly determine the calorie content of your meals and snacks to make informed dietary choices. Grams to calories is a conversion used in nutrition to determine the caloric content of food. Our online tool provides accurate conversion:

  • from macronutrients (protein, carbohydrates, and fats) in grams or pounds
  • to energy in joules (J), calories (kcal)

Each macronutrient (protein, carbohydrates, and fats) has a specific caloric value per gram. Proteins and carbohydrates both contain 4 calories (kcal) per gram. Fats contain 9 calories (kcal) per gram. The conversion between calories (kcal) and joules (J) is: 1 joule = 0.24 calories (kcal) and 1 calorie (kcal) = 4.184 joules. To convert calories to joules, multiply the number of calories by 4.18. To convert joules to calories, divide the number of joules by 4.18.

What are Macronutrients?

Macronutrients are the essential nutrients your body needs in large amounts to function properly. They provide the energy your body requires for daily activities and support growth and repair. The three primary macronutrients are:

  • Carbohydrates: are the primary source of energy for the body and fuel your brain and muscles. They are found in foods like bread, pasta, rice, fruits, and vegetables. Carbohydrates are broken down into glucose, which fuels your cells.
  • Proteins: are essential for building and repairing tissues. They are found in meat, poultry, fish, eggs, dairy products, legumes, and nuts. Proteins are broken down into amino acids, which support various biochemical processes in the body.
  • Fats: provide energy to insulate organs, protect cells, and aid in vitamin absorption. They are found in oils, butter, fatty meats, nuts, and seeds. Fats are important for hormone production and cell membrane health.

What Is Calorie?

A calorie is a unit of energy. The term "calorie" is scientifically defined as the amount of energy needed to raise the temperature of 1 gram of water by 1 degree Celsius. However, the calorie we talk about is the amount of energy in what we eat and drink, the calories in food provide energy in the form of heat so that our bodies can function even at rest.
