How do you convert from kJ to J?
To convert a kilojoule measurement to a joule measurement, multiply the energy by the conversion ratio. The energy in joules is equal to the kilojoules multiplied by 1,000.
Is kJ and J the same?
How many Joules in a KiloJoule? Joules and KiloJoules are units of the international system of units (SI) that measure energy. The standard symbol for Joule is J, whereas the symbol for KiloJoule is KJ. 1 J equals precisely 0.001 KJ, therefore there are 1,000 Joules in a KiloJoule.
What is the quantity of 1 calorie in kJ 1 calorie 4.184 J?
Accordingly, several different precise definitions of the calorie have been used. The amount of energy equal to exactly 4.184 J (Joules) and 1 kJ = 0.239 kcal.
How do you convert kcal to 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. For example, a medium-sized banana (118 grams) provides 105 calories (kcal) or 439 kJ ( 2 ).
How do you convert kJ mol to J?
Re: How to convert kJ/mol to J Answer: Cancel out the 1/mol unit by dividing by the Avogadro constant. Then convert kJ to J by multiplying the kJ value by 1000 (because of the conversion factor 1 kJ = 1000 J).
How many kJ are in a MJ?
Megajoule to Kilojoule Conversion Table
|Megajoule [MJ]||Kilojoule [kJ]|
|1 MJ||1000 kJ|
|2 MJ||2000 kJ|
|3 MJ||3000 kJ|
|5 MJ||5000 kJ|
Whats bigger kJ or J?
Thus, a kiloJoule (kJ) is 1000 Joules and a megaJoule (MJ) is 1,000,000 Joules. A related unit is the Watt, which is a unit of power (energy per unit time).
How many kcal should I burn a day?
The average person burns around 1800 calories a day doing absolutely nothing. According to the Healthy Eating Guide, sitting burns an estimated 75 calories per hour. A sedentary woman aged 19 to 30 burns 1,800 to 2,000 calories daily, while a sedentary woman aged 31 to 51 burns about 1,800 calories per day.
How many kcal should I eat a day?
An important part of a healthy diet is eating the right amount of calories, balancing the energy you put into your body with the energy you use. As a guide, men need around 2,500kcal (10,500kJ) a day to maintain a healthy body weight, and women need around 2,000kcal a day (8,400kJ).
How do you convert kJ mol 1 to J mol 1?
What does kJ mol 1 mean?
The heat energy given out or taken in by one mole of a substance can be measure in either joules per mole (J mol -1) or more commonly kilojoules per mole (kJ mol -1).
Which is greater a kJ or a kcal?
Please provide values below to convert kilocalorie (th) [kcal (th)] to kilojoule [kJ], or vice versa. Definition: A kilocalorie (symbol: kcal or Cal) is a unit of energy defined based on the calorie and is equal to 1000 calories or 4.1868 kilojoules.
How to convert kilocalories to J energy units?
Online calculator to convert kilocalories to joules (kcal to J) with formulas, examples, and tables. Our conversions provide a quick and easy way to convert between Energy units. The following is a list of definitions relating to conversions between kilocalories and joules. What is a kilocalorie (kcal)?
Which is larger 1 kJ or 1 joule?
How to Convert Kilojoule to Joule. 1 kJ = 1000 J. 1 J = 0.001 kJ. Example: convert 15 kJ to J: 15 kJ = 15 × 1000 J = 15000 J.
Is there a difference between kilojoules and calories?
In some cases, both kilojoules and kilocalories are displayed, though in countries such as the United States, only kilocalories are shown (often referred to as “Calories”) on food labels. Aside from this everyday use, kilojoules are used within scientific contexts around the world.
