I used E=mc2, and plugged in a microgram. Using 3*10^8 squared, I pulled out 5.16^-7 joules per kilogram. Is this correct?
..I'm curious as to know if I have the conversions correct. - Steven (age 22) Newport
A:
It's a little unclear if you're discussing a microgram or a kilogram. In the SI units , 1kg*(3*108 m/s)2= 9*1016Joules. For a microgram, you'd get 10-9 as much, i.e. 9*107 J.
