the are 1000 mg in a gram.
(a milligram is smaller than a gram, so there will be more of them, so you need to multiple - I always go through this thought pattern when I am deciding whether to multiply or divide)
5.97 x 10ˆ(27) x 1000 mg
You can do this in your head, there are 3 zeros in 1000 so the exponent goes up by 3
5.9 x 10^30
or, on the calculator it is best to use the exponential button (REMEMBER NOT TO PUT THE 10x AS WELL)
5.9 exp 27 x 1000 = 5.9 x 10^30
