Convert calorie (nutritional) to Rydberg constant
Please provide values below to convert calorie (nutritional) [Cal] to Rydberg constant [Ry], or Convert Rydberg constant to calorie (nutritional).
1 Cal = 1.9207e+21 Ry. To convert calorie (nutritional) to Rydberg constant, multiply the value by 1.9207e+21; to go the other way, divide by it (1 Ry = 5.2065e-22 Cal). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 Cal = 1.9207e+21 Ry
- 1 Ry = 5.2065e-22 Cal
- 10 Cal = 1.9207e+22 Ry

Calorie (Nutritional)
A calorie (Cal) is a unit of energy used to measure the amount of energy provided by food and beverages, specifically representing the amount of energy needed to raise the temperature of one kilogram of water by one degree Celsius.
History/Origin
The calorie was first introduced in the 19th century as a unit to quantify energy in nutrition. It has since become a standard measure in dietary and nutritional contexts, although the scientific community often prefers the joule as the SI unit of energy.
Current Use
Calories are widely used in nutrition to quantify the energy content of food and beverages, helping consumers manage dietary intake and energy balance. The term 'Calorie' with a capital 'C' typically refers to kilocalories (kcal), which are equivalent to 1,000 small calories.
Rydberg Constant
The Rydberg constant (Ry) is a physical constant that represents the highest wavenumber (inverse wavelength) of any photon in the hydrogen atom's emission spectrum, used to calculate spectral lines.
History/Origin
Named after the Swedish physicist Johannes Rydberg, the Rydberg constant was introduced in the late 19th century as part of Rydberg's formula to describe the spectral lines of hydrogen, significantly advancing atomic physics.
Current Use
The Rydberg constant is used in quantum physics and spectroscopy to determine energy levels of hydrogen and other hydrogen-like atoms, and in calculations involving atomic spectra and quantum mechanics.
