What is 1 joule per second equal to?
one watt
one joule per second is equivalent to one watt. The SI units for work and time are Joules and seconds, respectively. Therefore, One Watt was defined as a power of 1 Joule per second.
How much power is a megajoule?
One megajoule is equal to 1,000,000 joules, which are 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 106.
What does MJ stand for in nutrition?
What does MJ stand for in nutrition? 1 kilojoule (kJ) = 1,000 joules. 1 megajoule (MJ) = 1,000,000 joules. 1 kilocalorie (kcal) = 1,000 calories, or 1 Calorie.
How many Joules are in a MJ?

Is a watt AJ s?
The joules per second unit number 1.00 J/s converts to 1 W, one watt.
What is the SI unit for energy?
The SI unit of energy/work is the joule (J), named for English physicist James Prescott Joule (1818 – 1889). One joule also equals the energy required to move an electric charge of one coulomb through an electric potential difference of one volt (J = C · V).
How do you calculate Millijoules?
You need to determine the power density at the target surface in milliwatts/square cm and then multiply it by the number of seconds of exposure. For example, if the power density is 10 mW/cm2 then the energy dose is 10 x 480 (number of second in 8 minutes) so the energy dose is 4,800 millijoules.
What can a gigajoule power?
One GJ of electricity could make 1000 pots of coffee or keep a 60-watt light bulb continuously lit for six months. A GJ can measure energy from various types of power, such as electricity, natural gas and oil.
