E=mC^2...................................?

I have 3 questions here:-

1. What is the value of 'C'?

2. If unit of mass is 'gram' then what will be the unit of energy?

3. How is matter converted into energy in nuclear reactors? Does they use 'antimatter'?

    1. c is exactly 299,792,458 metres per second

    approx 300,000 km / second

    2. one erg is 1 g cm^2 s^−2

    3. by fission of uranium. Antimatter does not exist for long enough to be of use.

    3. Matter is not converted into energy. Mass is converted into energy. Mass is equivalent to energy density with a conversion factor of C^-2. The binding energy is liberated when 236U › 92Kr + 141Ba + 3 n. No matter is missing.

    The value of c is 3x10^8. the unit of energy is (kg)(mg/s^2). You have to convert grams to kilograms.
