How to convert electric power in watts (W) to energy in joules (J).You can calculate joules from watts and seconds, but you can't convert watts to joules since watt and joule units represent different quantities.Watts to joules calculation formulaThe energy E in joules (J) is equal to ...
One kilojoules is equal to 1000 joules:1kJ = 1000JThe energy E in joules (J) is equal to the energy in kilojoules (kJ) times 1000:E(J) = E(kJ)× 1000ExampleConvert 4kJ to joules.The energy E in joules (J) is equal to 4 kilojoules times 1000:...

A mass of 4.00 kilograms is completely converted into energy. What is this amount of energy in joules? Explain how to convert 6.60 x 1010 joules to British thermal units (Btu). Perform the indicated conversions. 52.61 kcal into joules and 124.2 kJ into kilocalories ...
As it happens, if you add a given amount of heat (Q) in joules to a system, or remove heat from that system, you can determine how much the system's temperature will change (∆T) in Celsius as long as you know the mass of the system (often a sample of water)min grams and it...
Amp to Watt conversion: Learn how to calculate watts from volts and amps in both DC and AC circuits. Understand the impact of power factor & reactance on the calculation.
You may have seen the abbreviation kPa, for kilopascals, printed on the pressure gauge you use for the tires of your car. One kilopascal equals approximately 0.145 pounds per square inch (psi). Because the kilopascal is a unit of pressure, you cannot convert it directly to joules, which ...
into the air. For water, this value is 540 calories/gram or 2.26 x 106joules/kilogram. So, if you can produce one liter of sweat, which is equal to 1000 g or 1 kg (density of water is 1 g/ml or 1 kg/l) in one hour, then 540,000 calories of heat can be removed from your...
The UPS then converts the battery's DC power back to AC power and runs it to the AC outlets for your electronics. If the power goes out, your computer will continue to run, feeding off the stored battery power. This will give you a few minutes to save your work and shut down your...
This means all the heat energy is converted into work. 3.Convert Calories to Joules: We know that 1 calorie is equivalent to 4.184 joules. Therefore, to convert 100 calories to joules, we can use the conversion factor: 100calories=100×4.184joules ...
