How to Convert Megacalories to Watt-Seconds

To convert a measurement in megacalories to a measurement in watt-seconds, multiply the energy by the following conversion ratio: 4,184,000 watt-seconds/megacalorie.

Since one megacalorie is equal to 4,184,000 watt-seconds, you can use this simple formula to convert:

watt-seconds = megacalories × 4,184,000

The energy in watt-seconds is equal to the energy in megacalories multiplied by 4,184,000.

For example, here's how to convert 5 megacalories to watt-seconds using the formula above.

watt-seconds = (5 Mcal × 4,184,000) = 20,920,000 Ws

How Many Watt-Seconds Are in a Megacalorie?

There are 4,184,000 watt-seconds in a megacalorie, which is why we use this value in the formula above.

1 Mcal = 4,184,000 Ws

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

What Is a Megacalorie?

One megacalorie is equal to 1,000,000 calories, which is the heat needed to raise the temperature of one gram of water from 14.5 to 15.5 degrees Celsius. One megacalorie is equal to 4.184 megajoules.

Megacalories can be abbreviated as Mcal; for example, 1 megacalorie can be written as 1 Mcal.

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]
