If I wanted to convert from nanograms to centigrams which directions would I move my decimal? Right or Left

Left

Explanation:

To convert from Nanograms to centigrams, you have to move the decimal to the left hand side.

          1 nanograms  = 1 x 10⁻⁹g

          1 centigrams  =  1 x 10⁻² g

So to convert from nanograms to centigrams,

          Multiply by 1 x 10⁻⁷ or move 7 places to the left
