- ›› Definition: Megajoule. The SI prefix mega represents a factor of 106, or in exponential notation, 1E6. So 1 megajoule = 106 joules. The joule (symbol J, also called newton meter, watt second, or coulomb volt) is the SI unit of energy and work. The unit is pronounced to rhyme with tool, and is named in honor of the physicist James Prescott Joule (1818-1889).

1 watt is equal to how many joules? The joule (/ˈdʒuːl/); symbol: J), is a derived unit of energy in the International System of Units. It is equal to the energy transferred to (or work done on) an object when a force of one newton acts on that object in the direction of its motion through a distance of one metre (1 newton metre or N⋅m).

- A megabyte is 10 6 or 1,000,000 bytes. One megabyte (abbreviated MB) is equal to 1,000 kilobytes and precedes the gigabyte unit of measurement. While a megabyte is technically 1,000,000 bytes, megabytes are often used synonymously with mebibytes, which contain 1,048,576 bytes (2 20 or 1,024 x 1,024 bytes).Megabytes are often used to measure the size of large files.hile a megabyte is technically 1,000,000 bytes, megabytes are often used synonymously with mebibytes, which contain 1,048,576 bytes (2 20 or 1,024 x 1,024 bytes).

- Residential electricity meter located in Canada. The kilowatt hour (symbol kWh) is a derived unit of energy equal to 3.6 megajoules. If the energy is being transmitted or used at a constant rate (power) over a period of time, the total energy in kilowatt-hours is the power in kilowatts multiplied by the time in hours. The kilowatt-hour is commonly used as a billing unit for energy delivered to consumers by electric utilities.
