1 kWh is a kilowatt-hour, in other words 1000 watts for one hour. That is 1000 Joules per second, for 3600 seconds.
So 1 kWh is 3,600,000 Joules, or 3600 kJ.

What mechanical work can be done using 100kW energy?
100 kW is not an energy, it is a power. It is the same as 100 kJ/sec (100,000 joules/second. The 100 kW - or 100 kJ/second - can be converted to 100 kW of mechanical power - or less, depending on the type of energy, and how much is wasted.
How many energy take 1.1 kw motor in hour?
Unit of energy is Joule. 1 Joule = 1 watt x 1 sec 1.1 KW = 1100 watt In 1 hour 1.1 KW motor would require 1100 watts x 60 = 66000 Joule / 66 KJ
TWO FURNACEs produce 10 kw of heat how large of an ac is required to cool this room?
10 kw = 10 kJ/sec = 9.478 BTU/sec = 34120 BTU per hour.
How many kj in 1 apple?
1000 kj, kj means thousand Jules.
How many kj in pizza?
8,000 to 10,000 kJ.
How many horsepower is in kw?
1.341hp per kW
How many horsepower is kw?
About 1.34hp per kW
How many kw are in 1 mgw?
1000 kw
How much work is done by a 5.5kw motor is rising a load in 5secs?
If the motor were perfectly efficient, then it would be expending 5.5 kW for 5 seconds. 5.5 kW x 1 (kJ/sec)/kW x 5 sec = 27.5 kJ. Of course no motor is 100% efficient, so the actual work will be less. A typical efficiency of electrical input power to shaft power for a motor of this size would be around 90% so we might estimate the actual work to be in the neighborhood of 24-25 kJ. Other inefficiencies in the way the load is raised can lower the actual work by even more.
How many calories are in 485 kj?
485 kJ is about 116 calories.
How many calories is 8700 kj?
8700 kJ is 2,077.96 calories.
How many calories are in 3.97 Kj?
3.97 kJ = 0.95 calories.
