Is Joule and Watt the same?
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..
How many joules does a person use per day?
Using a simple conversion (1000 calories = 1 Calorie, 1 calorie = 4.1868 J), this amounts to 8.37 x 106 joules ingested per day. This means that the average person expends ~8.37 x 106 joules of energy per day, since most of us are in some sort of equilibrium with our surroundings.
How many watts are in a gigajoule?
277,777.78 watt1 gigajoule (GJ) = 277,777.78 watt hours (Wh)
How many joules does it take to power a house?
Multiply and get about 396,000,000 joules a year. divide this by 365 and get a little over a mega joule a day. How much electricity does an ideal house use per month?
How much power is a MegaJoule?
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).
How many volts are in a gigajoule?
6,241,509,744,511,499,766,555,738,112.001 gigajoule (GJ) = 6,241,509,744,511,499,766,555,738,112.00 electron volts (eV)
What is the smallest unit of power?
Joule is the smallest unit of energy. But for some bigger calculation, some better unit is required. So, the unit used for electrical energy is watt-hour. Watts are the basic unit of power in which electrical power is measured or we can say that rate at which electric current is being used at a particular moment.
What does gigajoule mean?
Fast facts. One gigajoule (GJ) equals one billion joules (J). A gigajoule of natural gas is about 25.5 cubic metres at standard conditions. … The more carbon atoms in a hydrocarbon gas, the higher its gigajoule value.
How many joules are in a GJ?
1,000,000,000.00 joules1 gigajoule (GJ) = 1,000,000,000.00 joules (J)
What is the biggest Watt?
756 Watts times 3600 is 2.7MJ. The largest power unit used in discussion is the gigawatt, a thousand megawatts. The largest power plants can exceed one gigawatt by a bit – one GJ per second, 3.6 terajoules (TJ) per hour.
How many joules is dangerous?
Greater than 10 Joules is considered hazardous. Greater than 50 Joules is a lethal level.
How many joules is a punch?
The kinetic energy of a punch varies greatly. While beginners might only be able to muster a measly 37.5 joules of energy, experts can deliver over 400 joules, an amount roughly equal to getting shot by a handgun!
