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:...
How to convert energy in joules (J) toelectric powerinkilowatts (kW). You can calculate kilowatts from joules and seconds, but you can't convert joules to kilowatts, since joule and kilowatt units represent different quantities. Joules to kilowatts calculation formula The powerPin kilowatts (...
Converting units can be difficult, so when doing so it is important to remember to write down your computations step by step and to label all units. Joules (J) and calories, the derivative units of kilojoules (kJ) and kilocalories (kcal), are both used to measure energy. Keep in mind ...
Set up the mass-energy equivalence equation. Set your amount of joules equal to mass multiplied by the speed of light, which is 310^8 meters per second. As an example, if you have 5 joules of energy, the equation "E = mc^2" is set equal to "5 = m(310^8)^2" Step 2 Solve f...

Energy absorption/dissipation: This rating, given in joules, tells you how much energy the surge protector can absorb before it fails. A higher number indicates greater protection. Look for a protector that is at least rated at 200 to 400 joules. For better protection, look for a rating of...
Since one eV is 1.602 x 10-19Joules, use the above formula and multiply by that factor Joules = 1.986 x 10-23/nm You may recognize the number 1.602 x 10-19as the charge of an electron in Coulombs. How to convert delta microns or nanometers to delta cm-1(inverse cm) ...
If you took that 746 watts and ran it through an electric heater for an hour, it would produce 2,545 BTU (where a BTU is the amount of energy needed to raise the temperature of 1 pound of water 1 degree F). One BTU is equal to 1,055 joules, or 252 gram-calories or 0.252 food...
Joules Garcia/ Investopedia Having open conversations about finances is essential for any healthy romantic relationship. But no matter how long you’ve been lovebirds, bringing up money can feel awkward and uncomfortable. A February 2023 study by Bread Financial found that baby boomers tend to discu...
