For example: 10 kcal = 2.6114e+23 eV
About kilocalories and electronvolts
The Conversion Formula
To convert kilocalories to electronvolts, multiply the value by the conversion factor: 1 kcal = 2.6114e+22 eV. For a worked example, suppose you need to convert 25 kcal to electronvolts: 25 × 2.6114e+22 = 6.5286e+23 eV. To convert in the opposite direction, divide by 2.6114e+22, or equivalently multiply by 3.8293e-23.
About kilocalories
The kilocalorie (kcal) is what we colloquially call a 'Calorie' (capital C) on food labels in the US. It equals 1,000 small chemistry calories. It represents the energy required to heat 1 kilogram of water by 1°C. Confusion between calories and Calories is one of the most common unit errors in the world! kilocalories are commonly used in US Food labels, Diet apps, Fitness trackers, and Nutrition science, Body metabolic rate.
An apple contains about 95 kilocalories (Calories).
About electronvolts
The electronvolt (eV) is the tiny unit of energy used in particle physics. It is the energy gained by an electron accelerating through 1 volt. It is essential for describing photon energy, chemical bonds, and nuclear reactions. electronvolts are commonly used in Particle physics, Semiconductors, Nuclear energy, and Chemistry bonds, Microscopy.
A photon of visible light has an energy of about 2-3 eV.
When Would You Convert kilocalories to electronvolts?
Converting between kilocalories and electronvolts is one of the most common energy conversions. You might need this conversion when working with international specifications, following instructions written for a different measurement system, or comparing values across different standards. Having the conversion factor (1 kcal = 2.6114e+22 eV) memorized or bookmarked can save time in professional and everyday contexts alike.
