the basic is 'J' however in si units it is 'N m'
No, to convert from cal. to joules 1 cal. = 4.18400 joules , then 1KCal = (4.18400 *10^-3) joules so 3.25 kcal doesn't equal 3.25 Joules
Joules are the metric units used to measure energy. When you are working with any form of energy you state them in joules.
It's impossible. Nanometers are units of distance and Joules are units of energy.
Voltage is electrical pressure and Joules is a power rating so other info is needed
1 erg
No element has the symbol J. It's the symbol for the energy unit joules, though.
just 'J' so kJ for kilojules, you can google this easily
Depends on the type of calorie you're asking about. A "small calorie" which uses the symbol 'cal' is equivalent to about 4.18 Joules. A "large calorie" which uses the symbol 'Cal' is equivalent to about 4.18 Kilo Joules.
'J' is 'Joules' of energy, be it mechanical, heat, electric etc., Named after James Joule a Staffordshire, England , chemist. The basic S.I. units of the J (Joule) are 'kg*m^(2)s^(-2), somtimes written as kg(m/s)^(2) kJ (kilo Joules)= thousands of Joules ( of energy). e.g. 1000 J = 1 kJ
There are 56,000 joules in 56 kilojoules. This is because there are 1,000 joules in a kilojoule.
To convert from kilo joules to joules you have divide by 1000 as 1 kilo joule is equal to 1000 joules. E.g. 2 kilo joules equals 2000 joules.
In the context of science and engineering, 'power' (symbol: P ) is defined as the 'rate of doing work'. It's measured in joules per second which, in SI, is given the special name, the watt (symbol: W).
A petajoule is 1015 joules (Quadrillion joules)
4.18400 joules = 1 calorie, so 12.552 joules = 3 calories
The symbol used to show a transfer of energy is an arrow pointing from the energy source to the recipient of the energy. It typically represents the direction of the energy flow between the two entities.
To convert joules to kilojoules, divide the number of joules by 1000. For example, 1 kilojoule = 1000 joules, 5000 joules = 5 kilojoules.
148 calories is 619.6 joules. Since one calorie = 4.18 joules then you multiply that number by 148 and you get 618.64 joules (619 rounded)
