How to Convert Megacalories to Watt-seconds

To convert a megacalorie measurement to a watt-second measurement, multiply the energy by the conversion ratio. One megacalorie is equal to 4,184,000 watt-seconds, so use this simple formula to convert:

watt-seconds = megacalories × 4,184,000

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

For example, here's how to convert 5 megacalories to watt-seconds using the formula above.
5 Mcal = (5 × 4,184,000) = 20,920,000 Ws

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

Megacalories

One megacalorie is equal to 1,000,000 calories, which are 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.

Watt-seconds

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]
