kJ to Calorie Formula: Calories = kilojoules / 4.184 kJ to Calorie Definition If you want to learn how to convert kilojoules to calories with just the click of a mouse then you have come to the right place!
The calories nutritional / food unit number 0.24 Cal converts to 1 kJ, one kilojoule. It is the EQUAL energy value of 1 kilojoule but in the calories nutritional / food energy unit alternative. Conversion chart – kilojoules to calories nutritional / food 1 kilojoule to calories nutritional / food = 0.24 Cal
1 Calorie equals 4.186 kilojoules (4.2 or simply 4 is close enough for a quick conversion). For example, a slice of bread supplies 290 kilojoules or (290 divided by 4) 70 Calories. Kilojoules are difficult to grasp if you don’t have a feel for the numbers. So here’s a handy guide to make things more ‘friendly’.
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. All you have to do is enter the value and select the energy unit then press Convert to get the other units of energy. Which are the units for food energy?
We convert kj to Cal and vice-versa by multiplying or dividing by the fixed conversion rate. One calorie (cal) is equal to 4.184 joules (J). This means that one Calorie/kilocalorie (Cal/kcal) is equal to 4.184 kilojoules (kJ). The practical formula is:
Answer: Divide the amount of kJs by 4.184 then multiply by.25. Calories burned cycling are dependent on your Gross Metabolic Efficiency, but for most people it’s between 20-25%. That means for every Calorie you burn produces around 1.045 kilojoules. For practical reasons, most cyclists approximate 1 kJ is equal to 1 Calorie.
Next, let’s look at an example showing the work and calculations that are involved in converting from kilojoules to calories (kJ to cal). Kilojoule to Calorie Conversion Example Task: Convert 4 kilojoules to calories (show work) Formula: kJ ÷ 0.004184 = calories Calculations: 4 kJ ÷ 0.004184 = 956.02294455 calories Result: 4 kJ is equal to …
These days, many nutrition labels measure in kilojoules, which is the equivalent of 4.2 Calories, so a 200-degree rise would mean an 840 kilojoule food. (These numbers are expressed on most food labels as “kj” or “Cal”.)
Total the calories for each macronutrient. Now that you know how the calories are divided up, add together each individual count to get the combined calorie count for one serving of the item. Going off the previous example, 80 + 140 + 135 = 355 calories. This number should correspond with the estimate displayed on the item’s packaging.
b. Divide (x) the number of fat calories by the total number of calories in the food item = % fat content. * 1 gram of fat contains 9 calories (kcal) 2) Saturated Fat: a. Multiply the grams of saturated fat by 9 = (xx) the number of saturated fat calories in the food item. b.
