Suppose that you find in a reference book that the volume of all the oceans is [tex]1.4 \times 10^9 \text{ km}^3[/tex]. To find the mass, you can use the density of water, also found in this reference book, but first, you must convert the volume to cubic meters. What is this volume in cubic meters?

1(km)cubed = (1,000 m) x (1,000 m) x (1,000 m) = 1 billion cubic meters
1.4 x 10 to the 9 cubic km = 1.4 x 10 to the 9 x (10 to the 9 cubic meters) =
1.4 x 10 to the 18 cubic meters.

The volume of all the oceans in cubic meters is 1.4 × 1 0 18 m 3 , which is found by converting from cubic kilometers using the relation that 1 cubic kilometer equals 1 × 1 0 9 cubic meters. Therefore, the conversion involves multiplying the volume in cubic kilometers by 1 0 9 .
