Symbol. (metrology) Symbol for exajoule, an SI unit of work or energy equal to 10 18 joules .
What is PJ unit?
The joule is the standard unit of energy in general scientific applications. One joule is the equivalent of one watt of power radiated or dissipated for one second. One petajoule is 1015 joules (1 million billion) or 278 gigawatt hours.
How many joules are in an EJ?
The exajoule (EJ) is equal to one quintillion (10 18 ) joules .
What is the unit of power J S?
Watts are defined as 1 Watt = 1 Joule per second (1W = 1 J/s) which means that 1 kW = 1000 J/s. A Watt is the amount of energy (in Joules) that an electrical device (such as a light) is burning per second that it’s running.
What unit uses J?
The joule (symbol J) is the SI unit of energy—a measure of the capacity to do work or generate heat. One joule equals the work done (or energy expended) by a force of one newton (N) acting over a distance of one meter (m).
How much do PJs get paid?

Which will be is unit of power?
The dimension of power is energy divided by time. In the International System of Units (SI), the unit of power is the watt (W) , which is equal to one joule per second.
Is power a watt?
Power is a measure of the rate at which energy flows , and in electrical systems it is measured in watts (W).
Is newton a derived unit?
But some physical quantities—like force, area, and volume—are better described by derived units. ... This derived unit of force is called a newton and has the symbol N. So, one newton is one kilogram-meter divided by seconds squared! There are 22 named SI derived units.
What is the smallest unit of power?
The smallest unit of power is Milliwatt .
Is Joule a derived unit?
| Derived quantity | energy, work, quantity of heat | Name | joule | Symbol | J | Expression in terms of other SI units | N·m | Expression in terms of SI base units | m 2 ·kg·s – 2 |

What is the formula of 1 Joule?
Work (Joule)= F × D = [M 1 L 1 T – 2 ] × [L 1 ] = [M 1 L 2 T – 2 ]. Therefore, Joule is dimensionally represented as [M 1 L 2 T – 2 ] .
