About Kilocalorie

The kilocalorie (kcal) is 1,000 calories in the nutrition sense—often labeled “Calorie” on food packaging. Here 1 kcal = 4,184 J (thermochemical calorie definition used in this tool).

About Megaelectronvolt

A megaelectronvolt is 10^6 eV and appears in nuclear and particle physics contexts.

How to convert kilocalories to megaelectronvolts

1 kilocalorie is equal to 2.61144740e+16 megaelectronvolt when both are expressed in joule-equivalents:

1 kcal = (4,184 J ÷ 1.602176634e-13 J) mev = 2.61144740e+16 mev

Each kilocalorie is defined as 4,184 J and each megaelectronvolt as 1.602176634e-13 J in this tool, so one kcal equals 4,184 ÷ 1.602176634e-13 mev = 2.61144740e+16 mev.

Let d(kcal) be the numeric amount in Kilocalorie (kcal), and d(mev) the amount in Megaelectronvolt (mev). Then:

d(mev) = d(kcal) × (4,184 / 1.602176634e-13)

Equivalently, divide by how many kcal fit into one mev (joules per mev divided by joules per kcal):

d(mev) = d(kcal) ÷ 3.82929406e-17

Or: megaelectronvolt = kilocalorie ÷ 3.82929406e-17

Examples

Example #1: Convert 1 kcal to megaelectronvolt

1 kcal = 1 kcal × (4,184/1.602176634e-13) mev = 26114473967500000 mev

1 kcal = 1 kcal ÷ 3.82929406e-17 = 26114473967500000 mev

Example #2: Convert 10 kcal to megaelectronvolt

10 kcal = 10 kcal × (4,184/1.602176634e-13) mev = 261144739675000000 mev

10 kcal = 10 kcal ÷ 3.82929406e-17 = 261144739675000000 mev

Summary

To convert Kilocalorie to Megaelectronvolt, multiply the value in kcal by the ratio of joules per kcal divided by joules per mev. Equivalently: value_mev = value_kcal × (4184 / 1.602176634e-13). Numerically, 1 kcal equals 26114473967543828 mev.

Relationship context

You are converting between food / nutrition energy (calories) (Kilocalories) and atomic-scale energy (electronvolts) (Megaelectronvolts). All values are mapped through joules first. The numeric factor is 2.611447e+16.
