To convert a measurement in megajoules to a measurement in watt-seconds, multiply the energy by the following conversion ratio: 1,000,000 watt-seconds/megajoule.

Since one megajoule is equal to 1,000,000 watt-seconds, you can use this simple formula to convert:

watt-seconds = megajoules × 1,000,000

The energy in watt-seconds is equal to the energy in megajoules multiplied by 1,000,000.

For example, here's how to convert 5 megajoules to watt-seconds using the formula above.
watt-seconds = (5 MJ × 1,000,000) = 5,000,000 Ws

How Many Watt-Seconds Are in a Megajoule?

There are 1,000,000 watt-seconds in a megajoule, which is why we use this value in the formula above.

1 MJ = 1,000,000 Ws

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

What is a Megajoule?

One megajoule is equal to 1,000,000 joules, which is the energy equal to the force on an object of one newton at a distance of one meter.

The megajoule is a multiple of the joule, which is the SI derived unit for energy. In the metric system, "mega" is the prefix for millions, or 106. Megajoules can be abbreviated as MJ; for example, 1 megajoule can be written as 1 MJ.

What is a Watt-Second?

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]
