How to Convert Watt-seconds to Megaelectronvolts

To convert a watt-second measurement to a megaelectronvolt measurement, multiply the energy by the conversion ratio.

Since one watt-second is equal to 6,241,509,343,260.2 megaelectronvolts, you can use this simple formula to convert:

megaelectronvolts = watt-seconds × 6,241,509,343,260.2

The energy in megaelectronvolts is equal to the watt-seconds multiplied by 6,241,509,343,260.2.

For example, here's how to convert 5 watt-seconds to megaelectronvolts using the formula above.
5 Ws = (5 × 6,241,509,343,260.2) = 31,207,546,716,301 MeV

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


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]


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