From the basics conversions:
1 nanogram is equivalent to 1 * 10^-15 megagrams
To convert 7.02 * 10^-10 nanograms to megagrams, all you have to do is cross multiplication as follows:
1 nanogram ................> 1 * 10^-15 megagrams
7.02 * 10^-10 nanograms ...............> ?? megagrams
megagrams = (7.02*10^-10 * 1*10^-15) / (1) = 7.02 * 10^-25 megagrams
