What unit can be used to represent 1 million joules of energy?
Exa (E=1018). 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). Power units can be converted to energy units through multiplication by seconds [s], hours, [h], or years [yr].
What are the units equivalent to one joule of energy?
1 Joule (J) is the MKS unit of energy, equal to the force of one Newton acting through one meter. 1 Watt is the power from a current of 1 Ampere flowing through 1 Volt. 1 kilowatt is a thousand Watts.
What is a joule equivalent to?
Joule, unit of work or energy in the International System of Units (SI); it is equal to the work done by a force of one newton acting through one metre. Named in honour of the English physicist James Prescott Joule, it equals 107 ergs, or approximately 0.7377 foot-pounds.
What is amount of joule in 1 unit?
1 unit = 3.6×10^6 joules or 3600000 joules. punineep and 45 more users found this answer helpful. Thanks 27.
Which is the largest unit of energy?
Joule
In the SI unit system, Joule (J) is considered as the largest unit of energy.
How many joules is one watt?
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 is one joule equal to one energy unit?
In more fundamental terms, 1 joule is equal to: 1 J = 1 kg.m2/s2 Since energy is a fundamental physical quantity and it is used in various physical and engineering branches, there are many energy units in physics and engineering.
Where did the unit joule get its name?
Joule is a derived unit of energy and it is named in honor of James Prescott Joule and his experiments on the mechanical equivalent of heat. In more fundamental terms, 1 joule is equal to:
Which is a unit of energy equal to one hour?
A unit of energy equal to one kW applied for one hour; running a one kW equipment for one hour would dissipate one kWh of electrical energy as heat. The kilowatt-hour (symbolized kWh) is a unit of energy equivalent to one kilowatt (1 kW) of power expended for one hour (1 h) of time. 1 kWh = One thousand watt hours.
We all know the “Watt” is a unit of power consumption and have an idea how quickly a 1500 Watt kettle boils water. The unit of energy is the “Joule” – a Watt is just a flow of one Joule per second. The other popular unit of power is the “horsepower”. The conversion is that one horsepower = 756 Watts.
