What is 158 Kilocalories in Kilojoules?

158 Kilocalories = 661.072 Kilojoules

How to convert 158 Kilocalories to Kilojoules

To convert 158 Kilocalories to Kilojoules you have to multiply 158 by 4.184, since 1 Kilocalorie is 4.184 Kilojoules. The result is the following:

158 kcal × 4.184 = 661.072 kJ

158 kcal = 661.072 kJ

We conclude that one hundred fifty-eight Kilocalories is equivalent to six hundred sixty-one point zero seven two Kilojoules:

158 Kilocalories is equal to 661.072 Kilojoules.

Therefore, if you want to calculate how many Kilojoules are in 158 Kilocalories you can do so by using the conversion formula above.

Definition of units

Let's see how both units in this conversion are defined, in this case Kilocalories and Kilojoules:

Kilocalorie (kcal)

Calories are units of energy. Various definitions exist but fall into two broad categories. The first, the small calorie, or gram calorie (symbol: cal), is defined as the approximate amount of energy needed to raise the temperature of one gram of water by one degree Celsius at a pressure of one atmosphere. The second is the large calorie or kilogram calorie (symbol: Cal), also known as the food calorie and similar names, is defined in terms of the kilogram rather than the gram. It is equal to 1000 small calories or 1 kilocalorie (symbol: kcal). Although these units relate to the metric system, all of them have been considered obsolete in science since the adoption of the SI system. The unit of energy in the International System of Units is the joule. One small calorie is approximately 4.2 joules (so one large calorie is about 4.2 kilojoules). The factor used to convert calories to joules at a given temperature is numerically equivalent to the specific heat capacity of water expressed in joules per kelvin per gram or per kilogram. The precise conversion factor depends on the definition adopted.

Kilojoule (kJ)

The kilojoule (symbol: kJ) is equal to one thousand joules. Nutritional food labels in most countries express energy in kilojoules (kJ). One square metre of the Earth receives about 1.4 kilojoules of solar radiation every second in full daylight.
