Question

1 MeV is equal to...........
..............

Answer 1

we know that when we use kilo we multiply the answer with 10³

in the above question M stands for Mega

in the case of Mega we multiply the answer with 10⁶

we know that one electron volt (eV) = 1.602 × 10⁻¹⁹ Joules

1Mega eV = 10⁶ × 1.602 × 10⁻¹⁹ Joules = 1.602 × 10⁻¹³ Joules

⇒ 1MeV = 1.602 × 10⁻¹³ Joules
