How to Convert Megaelectronvolts to Watt-seconds

To convert a megaelectronvolt measurement to a watt-second measurement, multiply the energy by the conversion ratio. One megaelectronvolt is equal to 1.6022E-13 watt-seconds, so use this simple formula to convert:

watt-seconds = megaelectronvolts × 1.6022E-13

The energy in watt-seconds is equal to the megaelectronvolts multiplied by 1.6022E-13.

For example, here's how to convert 5,000,000,000,000 megaelectronvolts to watt-seconds using the formula above.
5,000,000,000,000 MeV = (5,000,000,000,000 × 1.6022E-13) = 0.801088 Ws

Megaelectronvolts and watt-seconds are both units used to measure energy. Keep reading to learn more about each unit of measure.


Megaelectronvolts can be abbreviated as MeV; for example, 1 megaelectronvolt can be written as 1 MeV.


The watt-second is a measure of electrical energy equal to one watt of power over a one second period. One watt-second is equal to 1/3,600 of a watt-hour or one joule.

Watt-seconds are usually abbreviated as Ws, although the formally adopted expression is W·s. The abbreviation W s is also sometimes used. For example, 1 watt-second can be written as 1 Ws, 1 W·s, or 1 W s.

In formal expressions, the centered dot (·) or space is used to separate units used to indicate multiplication in an expression and to avoid conflicting prefixes being misinterpreted as a unit symbol.[1]
