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 .
What is a Petajoule of gas?
A joule is a measure of thermal energy. ... A terajoule is a trillion of them, a gigajoule is one billion joules, and a megajoule is a mere one million of them. Just one petajoule is enough gas to fuel demand from a fair-sized regional centre such as Wollongong, or Penrith, or Warrnambool for a year .
What is joules PJ?
The picojoule (pJ) is equal to one trillionth (10 − 12 ) of one joule.
How many MW are in a PJ?
| Megawatt [MW] Petajoule/second [PJ/s] | 1 MW 1.0E-9 PJ/s | 2 MW 2.0E-9 PJ/s | 3 MW 3.0E-9 PJ/s | 5 MW 5.0E-9 PJ/s |

What is EJ in energy?
(metrology) Symbol for exajoule, an SI unit of work or energy equal to 10 18 joules .
What is a unit of gas?
Units of gas measure the amount of gas consumed at a property. 1 unit of gas is equal to one kilowatt hour (kWh) of gas used . ... This is then converted to Units (kWh’s) by your energy supplier on your gas bill. You will then be charged an amount in pence per kWh (unit) of gas used.
How much is a cubic foot of natural gas worth?
Average price of natural gas per therm
In January 2020, the national average price was $9.52 per thousand cubic feet. That’s $0.95 per Ccf . And at the 2019 national average heat content of 1,037 Btu per cubic foot, it’s a natural gas therm price of $0.92.
How many Picojoules are in a Joule?
| Energy (kJ) Energy (J) | 1 kJ 1000 J | 2 kJ 2000 J | 3 kJ 3000 J | 4 kJ 4000 J |

What are joules Watts?
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. So a 60W bulb is burning 60 Joules of energy every second you have it turned on.
How do you convert MWh to MW?
The formula used to calculate megawatt-hours is Megawatt hours (MWh) = Megawatts (MW) x Hours (h) . To convert megawatt hours to megawatts, you are going to need to divide the number of megawatt hours by the number of hours. In other words: Megawatts (MW) = Megawatt hours (MWh) / Hours (h).
How do you convert MWh to GJ?
To convert a megawatt-hour measurement to a gigajoule measurement, multiply the energy by the conversion ratio. The energy in gigajoules is equal to the megawatt-hours multiplied by 3.6 .
What can 1 Joule of energy do?
One joule equals the work done (or energy expended) by a force of one newton (N) acting over a distance of one meter (m) . One newton equals a force that produces an acceleration of one meter per second (s) per second on a one kilogram (kg) mass. Therefore, one joule equals one newton•meter.
What does EJ measure?
Large-scale units.
In describing national or global energy budgets, it is common practice to use large-scale units based upon the joule , Btu, and kWh: Exajoule (EJ): 1 EJ = 10 18 J. Quadrillion Btu(quad): 1 quad = 10 15 Btu = 1.055 EJ.
What are the common units of energy?
- Barrel of oil.
- Calorie.
- Horsepower.
- Joule (J)
- Kilowatt-hour (kWh)
- Kilowatt (kW)
- Megajoule (MJ)
- Megawatt (MW)
How do I calculate my gas usage?
- Take away your last reading from your current reading. This is how many units you’ve used.
- If you’ve got a metric meter (m3), you can ignore this step. ...
- Multiply this number by the calorific value. ...
- Multiply this number by 1.02264. ...
- Divide this number by 3.6. ...
- Multiply this number by the price-per-kWh.
