WebAbout WebA kilojoule is a unit of measure of energy, in the same way that kilometres measure distance. Food energy used to be measured in Calories (Cal) and some countries still use those units. The conversions are as follows: 1 kJ = 0.2 Cal 1 Cal = 4.2 kJ Kilojoules in food The food and drinks we eat provide energy, which is measured in kilojoules.

WebSep 7, 2024 · How do you find energy in joules from wavelength? Use Planck’s equation E = h x c / λ and substitute the values of the wavelength (λ), Planck’s constant in joules (h = 6.6261 × 10⁻³⁴ J⋅s), and speed of light (c = 299792458 m/s). With these units, you’ll get an energy result in joules (J). That’s it!
