[Value of ncal [IT]] = [Value of meV] * 3.8267329822299E-14

##### ncal [IT](nanocalorie)

A nanocalorie (ncal) is a unit of energy in the International System of Units (SI) and is equal to one billionth (1 x 10^-9) of a calorie. Specifically, it refers to the International Table (IT) Calorie, which is defined as the amount of heat required to raise the temperature of one gram of water by 1 degree Celsius. In the field of energy, the nanocalorie is a very small unit often used to measure energy at molecular or atomic levels, for instance in the fields of chemistry, physics, or biophysics.1 IT Calorie equals 4.1868 Joules, so 1 ncal equals 4.1868 x 10^-9 Joules.

##### MeV(megaelectron volt)

The megaelectron volt (MeV) is a unit of energy in the field of physics, particularly in particle and nuclear physics. It represents one million electron volts (eV). An electron volt is the amount of kinetic energy gained or lost by a single electron when it is accelerated through an electric potential difference of one volt.

In the context of energy, 1 eV is equal to 1.602 x 10^-19 joules. Therefore, 1 MeV is equal to 1.602 x 10^-13 joules. Because the electron volts (and by extension, megaelectron volts) are relatively small units of energy, they are used to describe the energies of particles, like electrons, protons, and photons, at the atomic and subatomic scale.

In nuclear and high-energy particle physics, MeV is frequently used to express the masses of subatomic particles through the concept of mass-energy equivalence, given by Einstein's famous equation E=mc^2. This means that an MeV can also be considered a unit of mass for subatomic particles.

##### meV(millielectron volt)

The millielectron volt (meV) is a unit of energy commonly used in the field of physics, particularly in atomic, molecular, nuclear, and particle physics. It is a submultiple of the electron volt (eV), where 1 electron volt is defined as the amount of kinetic energy gained by a single electron when it is accelerated through an electric potential difference of one volt.

1 millielectron volt (meV) is equal to one-thousandth (1/1000) of an electron volt, or 0.001 eV. Its value in the International System of Units (SI) is about 1.602 x 10^(-22) joules.

This unit is used to describe energy levels, energy differences or energy transfers on a small scale, such as in atomic and molecular interactions, quantum states transitions, and properties of subatomic particles. Because these interactions involve very small amounts of energy, the use of meV makes it more practical and convenient to express and compare these values without resorting to scientific notation or very small decimal numbers.
