MeV to kJ Converter - Mega Electron Volt to Kilojoule

Mega Electron Volt (MeV) to Kilojoule (kJ)

Direct answer

1 MeV = 1.60217663e-16 kJ

kJ = MeV × 1.60217663e-16

Converter

Input

MeV

Result

1.60217663e-16kJ

kJ = MeV × 1.60217663e-16

MeV = kJ × 6.24150907e+15

Example: 10 MeV = 10 × 1.60217663e-16 = 1.60217663e-15 kJ.

Express both MeV and kJ in the same base unit J (joule), then cancel the shared base unit.

1
Rewrite MeV in the base unit
$1 MeV = 1.60217663 \times 1 0^{- 13} J$
2
Rewrite kJ in the base unit
$1 kJ = 1, 000 J$
3
Forward conversion
$1 MeV = \frac{1.60217663 \times 1 0 ^{- 13} J}{1 , 000 J} \times 1 kJ = \frac{1.60217663 \times 1 0 ^{- 13}}{1 , 000} kJ = 1.60217663 \times 1 0^{- 16} kJ$
4
Reverse conversion
$1 kJ = \frac{1 , 000 J}{1.60217663 \times 1 0 ^{- 13} J} \times 1 MeV = \frac{1 , 000}{1.60217663 \times 1 0 ^{- 13}} MeV = 6.24150907 \times 1 0^{15} MeV$
