This calorie converter helps you transform calories to kilojoules and the other way around plus you can also use joules or kilocalories.
Below the form you can discover more on this topic and also the most used conversions. How does this calorie converter work? Do you know how to convert calories to kilojoules or how to convert kilojoules to calories? It works either way so it is a kilojoule to calorie converter, a calorie to kilojoules converter and a kilocalorie to kilojoules converter all at the same time.
The units used to measure food energy are kilojoules kJ and Calories kCal. The common term defining how much energy a food contains or how much it is burned during various activities used to be calorie but now kilojoule is a term accepted internationally.
You can use the health tool above to find out the corresponding values in the other S. I units for the energy in foods. It will compute the value you enter in all energy units related: kJ, J, cal, kcal.
This is a unit that measures energy. The symbol is kJ. This unit is the multiple of the joule. The joule is the SI unit of energy and work. A calorie refers to a non SI unit of energy. Pay attention, there are two kinds of calories with different meanings:.
Small calorie: cal. It is times smaller than a food calorie. Large calorie kcal. So the Calories are the same thing with kilocalories and kcal. We will further on use the kcal definition. Calorie Converter. Select joules kilojoules calories kilocalories food. Which are the units for food energy? What is a kilojoule? Pay attention, there are two kinds of calories with different meanings: Small calorie: cal. How to convert calories to kilojoules?The Atwater system  is used in the food industry to determine the total calorific value of food by employing the method.
This system applies energy conversion factors to the macronutrients carbohydrate, fat, protein and fibre. The average values of energy are expressed as the number of calories per 1 gram of the macronutrient.Greenhouse supplies pots
For instance, if you have a food that contains 20g protein, you would multiply 20 by 4 to give 80 calories supplied by protein in that food. These figures were originally determined by using a bomb calorimeter and measuring the heat of food combustion and the resultant amount of energy the food produces .
There are a number of shortfalls when using the Atwater system to determine the total calorific value of a food. The energy conversion factors are estimates and are therefore likely to be associated with some inaccuracy when compared to the direct assessment method, bomb calorimetry.
The energy conversion factors for macronutrients as a whole are not clear cut. The calorie content of individual amino acids AAs were found to be different when calculated by correction of heat combustion .
Convert calories to kJ - Energy Conversions
However, the protein conversion factor of 4 calories per gram was derived as an average for the energy yield of all amino acids .
This means that if a food contains a large amount of the amino acid phenylalanine, which yields 6. The table below shows the heat of combustion produced by each AA used as the energy conversion factor. Figure 1: Heat of combustion of amino acids . The assumptions based on carbohydrates are even more problematic.
Firstly, the conversion factor does not distinguish between sugars, starch and dietary fibre. For example, monosaccharides have combustion heats of around 3. There are also sugar alcohols to consider, organic compounds that are derived from sugars — also known as polyols — all with a varying energy conversion factor; for example, xylitol provides 2. However, 2. Secondly, the Atwater method does not account for variants in fibre and resultant calories.
The extent of this degradation depends on the individual and the source of fibre. Fatty acids also differ in their heat of combustion; however, the difference is relatively small. For now, the use of energy conversion factors provides a method for estimating the available energy intake, although their limitations cannot be disregarded. Contrarily, it is worth considering the significance of these shortcomings and application to real life.
Although there may be slight variations in the energy yield of a food by calculation versus measurement by heat of food combustion, the differences may be so small that the values become negligible.

Us too, so we called up eminent nutritionist Dr Rosemary Stanton to find out. It turns out there is quite the history to the process. The bomb calorimeter consists of a sealed inner container where food is placed and filled with oxygen, which is highly combustible.Borgwarner turbo systems asheville nc
It's surrounded by water and scientists measure the temperature rise of the water to ascertain the amount of energy that is potentially available from the food. It takes 1 Calorie of energy to raise the temperature of 1 kilogram of water by 1 degree Celsius. That Calorie spelled with a capital C is not a typo — for scientists, a Calorie with an uppercase C is the same as a kilocalorie, which is equal to calories with a lowercase C.
For everyday people, when we talk about "calories" we're technically referring to kilocalories or Calories. Thanks for making that not at all confusing, scientists So when a set quantity of the food is burnt, if the temperature of the water rises by degrees, in theory, that amount of food would have Calories.
These days, many nutrition labels measure in kilojoules, which is the equivalent of 4.
These numbers are expressed on most food labels as "kj" or "Cal". Taking account of some losses that occur in the body when we eat protein, scientists were able to determine that, on average, each gram of fat gives you 37 kilojoules, while each gram of protein and carbohydrate gives you 17 kilojoules. Alcohol has 29 kilojoules for each gram. Over time, scientists have also realised that digestion is not a perfect mathematical equation, and certain types of fibre and fats can reduce the amount of energy our body can use.
As a result, some foods, such as nuts, should be adjusted to have a lower kilojoule count — but Dr Stanton says food composition tables are yet to catch up with this latest finding. Taking all of this into account, nutrition experts have now created extensive food composition tables that includes the amount of fat, protein and carbohydrates in foods.
If you're interested in calculating the amount of Calories in the sandwich you're about to eat or recipe you're about to make, you can go to Food Standards Australia New Zealand's NUTTAB database to search the nutritional composition the food. Dietitians, recipe developers and food manufacturers often invest in the FoodWorks program, which easily calculates the nutritional table.

Share Mail Tweet Pinterest.Each individuals caloric intake is determined by much more than your workouts. Use this calorie calculator to find out how many calories you really need. Reading a food label could give you the impression that everybody needs more or less the same things, in the same quantities, to be healthy. Not so!What is half of 33 1/4 inches
We all have different bodies, different goals, and different lifestyles, and the way we eat should reflect that. This calorie calculator will help you estimate the number of calories you're burning each day, and then help you determine a "target daily caloric intake" to aim for.
Once you have this number, you will be able to customize your nutrition to your physical goal, no matter if it's weight loss, muscle gain, or just being in better control of your health and the way you eat.The MOST Accurate CALORIE CALCULATOR - How to Calculate Your Maintenance Calories and TDEE
Not sure which goal is right for you? Then start with "maintenance. It is roughly equivalent to your total daily energy expenditure TDEEthe number of calories you burn each day.
But remember, it's just an estimate! Many of us either dramatically overeat or undereat on a day-to-day basis, and simply trying "maintenance" on for size for a few weeks can be an eye-opener that helps get us on track.
This is also why many nutritionists say before you ever think of cutting below maintenance—into what is known as a caloric deficit—you should spend some time simply tracking how you eat now, and then see how it feels to eat at maintenance. But let's say you're definitely ready to lose a few extra pounds.
Then by all means, select "fat loss. That may not sound like a big deficit, but it can be enough! And cutting more than that is almost never the place to start. Now, it's commonly believed that the calorie equivalent to 1 pound of fat is 3, calories.
Many people will push the envelope even further, decreasing their calories by 1, or more. However, this math doesn't always match up with reality.
