How do I make the following coversions, in standard exponential form?

Question

1)14.8g to micrograms
2)3.72 X 10-3kg to grams
3)66.3 L to cubic centimeters

1 g = 10^6 micrograms = 10^6 ug.

14.8 g x (10^6 ug/1 g) = 14.8 x 10^6 ug = 1.48 x 10^7 ug.

You do the others.
1 kg = 1000 g
1000 cc = 1 L

Answer 1

2) 3.72 x 10^-3 kg x (1000 g/1 kg) = 3.72 x 10^3 g

3) 66.3 L x (1000 cc/1 L) = 66.3 x 10^3 cc
