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 ...
How to convertelectric powerinwatts (W)to energy in kilojoules (kJ). You can calculate kilojoules from watts and seconds, but you can't convert watts to kilojoules since watt and kilojoule units represent different quantities. Watts to kJ calculation formula The energyEin kilojoules (kJ) is eq...
You can convert hours to seconds with the following formula: (Number of hours) x 3600 That is, the number of hours multiplied by 3600 equals the...
A joule is equal to one what times one meter? How can someone travel a distance of 41 meters but have a displacement of 0 meters? How to convert minutes to seconds with a formula What SI units are used to measure power? What is the formula to convert watts to amps?
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.
If you do your measurements on the CGS (centimeters, grams, seconds) system, force is expressed in dynes and work in ergs. You must convert these to newtons and joules to get the result in watts. Here are the conversion factors:
Step 1: Convert Horsepower to Watts Step 1: Convert Horsepower to Watts Since amps and volts are standard units, but HP is not, you need the power in watts to solve the equation. Since 1 HP = 746 W, the wattage in this example is: ...
The application software numerically integrates the power over time, which gives the mechanical work done in joules. This is scaled by the conversion factor to convert joules to kilocalories. The assumption made is that the body consumes four joules of chemical energy to do one joule of work...
(and the boulder) back down. In science, we say you have to doworkagainst the force of gravity to push the boulder up the hill. Doing work means you have to use energy: the muscles in your body have to convert sugar and fat to make the energy you need to push the boulder. Where...
378kJ to boil a liter of water is rather more energy than you might think. An energy-efficient lamp rated at 10 watts uses 10 joules of energy every second (because 1 watt means using one joule per second), so it would take it 37,800 seconds—about 10.5 hours—to use as much ...
