How do you convert kcal to kJ?
How do you convert kcal to kJ?
Calories may also be expressed as kilojoules (kJ). One calorie (kcal) equals 4.18 kJ or 4,184 joules (J) ( 1 ). To convert from calories to kJ, multiple calories by 4.18. Conversely, to convert from kJ to calories, divide kJ by 4.18.
How do you convert kcal to kJ mol?
How to Convert Kilocalories to Kilojoules. To convert a kilocalorie measurement to a kilojoule measurement, multiply the energy by the conversion ratio. The energy in kilojoules is equal to the kilocalories multiplied by 4.184.
How do you convert kJ to kcal?
How to convert from kilojoules to kcal
- Kilojoules to international kilocalories. 1 kcalIT = 4.1868 kJ. The energy in international kilocalories E(kcal-IT) is equal to the energy in kilojoules E(kJ) divided by 4.1868:
- Kilojoules to 15°C kilocalories. 1 kcal15 = 4.1855 kJ.
- Kilojoules to 20°C kilocalories. 1 kcal20 = 4.182 kJ.
How many joules are in a kcal?
The kilocalorie is thus equal to 1000 calories. This tool converts kilocalories to joules (kcal to j) and vice versa. 1 kilocalorie = 4186.8 joules.
Is kJ the same as KCAL?
Checking calories in food The calorie content is often given in kcals, which is short for kilocalories, and also in kJ, which is short for kilojoules. A kilocalorie is another word for what’s commonly called a calorie, so 1,000 calories will be written as 1,000kcals. Kilojoules are the metric measurement of calories.
Is kJ a kcal or calorie?
Which is bigger kJ or kcal?
How many kcal do we need per day?
As a guide, an average man needs around 2,500kcal (10,500kJ) a day to maintain a healthy body weight. For an average woman, that figure is around 2,000kcal (8,400kJ) a day. These values can vary depending on age, size and levels of physical activity, among other factors.
How many joules are there in 1.86 kcal?
How Many Joules are in a Kilocalorie? There are 4,184 joules in a kilocalorie, which is why we use this value in the formula above. Kilocalories and joules are both units used to measure energy.
How to convert a kJ to a kcal?
Kilocalorie (th) to Kilojoule Conversion Table Kilocalorie (th) [kcal (th)] Kilojoule [kJ] 0.01 kcal (th) 0.04184 kJ 0.1 kcal (th) 0.4184 kJ 1 kcal (th) 4.184 kJ 2 kcal (th) 8.368 kJ
Which is greater 300 calories or 1 kJ?
1 kJ = 239.005736 cal th. The energy in kilojoules E (kJ) is equal to the energy in thermochemical calories E (calth) divided by 239.005736: E (kJ) = E (calth) / 239.005736. Convert 300 cal th to kilojoules.
