Is kJ and J the same?
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.
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 do you convert kJ to J in physics?
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.
What kJ means?
kilojoule
A kilojoule is a unit of measure of energy, in the same way that kilometres measure distance. Food energy used to be measured in Calories (Cal) and some countries still use those units. The conversions are as follows: 1 kJ = 0.2 Cal. 1 Cal = 4.2 kJ.
Can kJ be converted to calories?
The formula to change kilojoules to calories is quite simple. Since one Cal is equal to 4.184 kJ, you just need to divide the kilojoule value by 4.184 to get the Cals equivalent. Dividing by 4.184 is the same as multiplying by 0.239.
How do you convert kilojoules per mole to joules per mole?
The formula to convert Kilojoule per Mole to Joule per Mole is 1 Kilojoule per Mole = 1000 Joule per Mole.
How many moles are in a Joule?
Since 1 mole = 6.0221407×1023 particles (atoms, molecules, ions etc.), 1 joule per mole is equal to 1 joule divided by 6.02214076×1023 particles, 1.66054×10−24 joule per particle.
How do I calculate kinetic energy?
To calculate kinetic energy:
- Find the square of the velocity of the object.
- Multiply this square by the mass of the object.
- The product is the kinetic energy of the object.
How do you find kJ?
kJ (Metric), energy The base unit conversion can be remembered using the equation E = mc2, where E is in joules, m is in kilograms, and c is the speed of light in meters per second. Type the number of kJ you want to convert in the text box, to see the results in the table.
How do you convert kilojoules to calories?
There are 4.184kJ in 1 food calorie (kcal). To roughly convert kilojoules to calories, divide your kJ figure by 4.2 or multiply it by 0.24.
