MeV to cal Converter - Mega Electron Volt to Calorie

Mega Electron Volt (MeV) to Calorie (cal)

Direct answer

1 MeV = 3.82929406e-14 cal

cal = MeV × 3.82929406e-14

Converter

Input

MeV

Result

3.82929406e-14cal

cal = MeV × 3.82929406e-14

MeV = cal × 2.6114474e+13

Example: 10 MeV = 10 × 3.82929406e-14 = 3.82929406e-13 cal.

Express both MeV and cal 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 cal in the base unit
$1 cal = 4.184 J$
3
Forward conversion
$1 MeV = \frac{1.60217663 \times 1 0 ^{- 13} J}{4.184 J} \times 1 cal = \frac{1.60217663 \times 1 0 ^{- 13}}{4.184} cal = 3.82929406 \times 1 0^{- 14} cal$
4
Reverse conversion
$1 cal = \frac{4.184 J}{1.60217663 \times 1 0 ^{- 13} J} \times 1 MeV = \frac{4.184}{1.60217663 \times 1 0 ^{- 13}} MeV = 2.6114474 \times 1 0^{13} MeV$

1 MeV = 3.82929406e-14 cal.

10 MeV = 3.82929406e-13 cal.

100 MeV = 3.82929406e-12 cal.

Use cal = MeV × 3.82929406e-14.

1 cal = 2.6114474e+13 MeV.

Use the conversion factor and round the result to the precision required by your calculation.
