kJ to Cal Converter

What is a kilojoule?

The energy required to carry an object a distance of one metre with a one-newton force is one kilojoule (1 kJ), which is equivalent to 1,000 joules. Kilojoules are multiples of the joule, the SI-derived unit of energy. In the metric system, “kilo” is the prefix for thousands (10³). Kilojoules (kJ) can be abbreviated; for example, 1 kilojoule is written as 1 kJ.

What is a calorie?

A calorie is the measure of heat necessary to elevate the temperature of one gram of water by one degree Celsius, specifically from 14.5°C to 15.5°C. The large calorie, or kilocalorie, is used to measure the energy content of meals, yet it is still commonly referred to as a calorie. People generally think of the small calorie when they hear the word calorie next to the large calorie.

How to Calculate kJ to Cal

A measurement in kJ to Cal Calculator can be converted to a measurement in calories by multiplying it by the conversion ratio, which is 239.005736 calories/kilojoule.

One kilojoule is equivalent to 239.005736 calories; thus, you can convert using this easy kJ to Cal formula:

                                  Calories = kilojoules × 239.005736

If you multiply the energy in kilojoules by 239.005736, you obtain the energy in calories.

For instance, you can use the formula above to change 5 kilojoules into calories.

                          Calories = (5 kJ × 239.005736) = 1,195.028681 cal

Small and Large Cal

The small calorie is the amount of heat needed to raise the temperature of 1 gram of water by 1°C at 1 atmosphere of pressure. On the other hand, the large calorie is the amount of energy needed to raise the temperature of 1 kilogramme of water by 1°C at the same pressure.

A large calorie, also known as a food calorie, serves as a unit of food energy

kJ to large Cal

1 Cal = 4.184 kJ

1 kJ = 0.239 Cal

1 Cal = 1 Kcal

The energy in large calories E(Cal) is equivalent to the energy in kilojoules E(kJ) multiplied by 0.239:

E(Cal) = E(kJ) × 0.239

For Example

Convert 0.6 kJ into Large calories.

E(Cal) = 0.6 kJ multiplied by 0.239 equals 0.1434 Cal.

kJ to Small/Thermochemical Cal

One calth is equivalent to 0.004184 kJ.

1 kJ = 239.0057 calth.

The energy in thermochemical calories (E(calth)) is equivalent to the energy in kilojoules (E(kJ)) multiplied by 239.0057:

E(cal) = E(kJ) multiplied by 239.0057

For Example

Convert 0.6 kJ to thermochemical Cal.

E(cal) = 143.4 calth × 239.0057 = 0.6 kJ

kJ is too small/15°C.

cal15 = 0.0041855 kJ.

1 kJ = 238.9201 cal.

The energy in kilojoules E(kJ) is equivalent to the energy in 15°C calories E(cal15) multiplied by 238.9201.

E(cal15) = E(kJ) multiplied by 238.9201.

For Example

Convert 0.6 kilojoules to calories at 15°C.

E(cal15) = 143.352 cal15 × 238.9201 = 0.6 kJ

Why convert kJ to Cal?

It important to understand the energy level of the meals you intake in order to lose weight effectively. Kilojoules (kJ) are the standard unit for measuring energy; however, calories (Cal) are used in many places across the world, including the United States. If you know more about calories or would rather record how much you eat each day in this unit, our converter makes it easy.

How to convert kj to cal on the Apple Watch

If you prefer not to depend on your paired iPhone, you have the option to alternate between Cal to kJ directly on the Apple Watch.

  • Open the Settings app on watchOS.
  • Navigate to the Workout section by scrolling to the bottom of the page.
  • Continue scrolling down and navigate to the Units of Measure section.
  • Calories, Kilocalories are available for selection. Tap on the unit that you prefer to select.

Instructions for converting kilojoules to calories on your iPhone

The Apple Watch’s small screen makes it easier to switch between kilojoules and calories on your iPhone.

  • Open the Watch app on your iPhone.
  • In the main My Watch tab, scroll down and click on Workout.
  • Scroll down once more and go to Units of Measure.
  • To choose between Calories, Kilocalories, and Kilojoules, tap the unit you wish.

It’s simple to select the unit you desire

Our instructions show you two ways to quickly change the Apple Watch’s unit of measure from kJ to Cal. The first is only your Apple Watch, but its size may make it harder. The second approach demands that you have a linked iPhone and provides a more comfortable perspective.

The results are consistent regardless of which approach you employ. You only need to conduct one of the two techniques once, and the modifications will be instantly synced across your Apple Watch and iPhone.
