**1 MeV Equals How Many Joules?**

**What is 1 MeV?**

MeV, or mega electronvolts, is a unit of energy commonly used in physics to express the energy of subatomic particles, such as electrons, protons, and ions. 1 MeV is equal to one million electronvolts.

**What is 1 Joule?**

A joule (J) is the unit of energy in the International System of Units (SI). It is defined as the energy expended when a force of 1 newton is applied over a distance of 1 meter. Joules are used to measure the energy of various forms of energy, including thermal, electrical, and mechanical energy.

**Conversion of 1 MeV to Joules**

Now, let's convert 1 MeV to joules. The conversion factor is:

1 MeV = 1.60217662 × 10^(-13) J

So,

1 MeV ≈ 1.602 × 10^(-13) J

**Conclusion**

In conclusion, 1 MeV is equivalent to approximately 1.602 × 10^(-13) joules. This conversion is important in physics, particularly in the fields of nuclear physics and particle physics, where energies are often expressed in MeV and need to be converted to joules for various calculations.
