E = MC^2
therefore:
M = E/C^2

I think you're looking for a number here. There isn't a defined number because the two are interchangable. That's the significance of the equation.
1 kg of mass has a theoretical energy content of 1 * (3e8)^2 = 9e16 Joules. A 2 kg mass will have twice the energy content. Of course, this is entirely theoretical.
Another way to look at this is through energy density. (J/kg). 9e16J/kg of mass is the energy density assuming mass-energy equivalence. To compare, dynamite has an energy density equal to aboiut 4e6J/kg.

M = E / C[squared]
Mass equals energy divided by the speed of light squared.
Did you want that for a particular object?

Start at the beginning:
E=mc^2
divide both sides by c^2
E/c^2 = m
m = E/c^2

hey
If E = MC² then
M = E / C² (E divided by C squared)

Uhm, you would need to provide E...
unless you are just talking about the formula
