Can someone please help me figure how to convert these measurements I am doing in practice problems?

Question

I am trying to figure out how to convert these measurements and I don't know how. Can someone help me out?

1. 456.8 cm3 = ___________ L

2. 1.9 hg = ____________ cg

3. 12.345 m = ________ mm

4. How many kiloliters are in 15.0 deciliters?

5. How many centigrams are in 22.65 grams?

6. How many millimeters are in 1500.0 meters?

Answer 1

These are all measurements in metric units, so conversion is simply a matter of multiplying or dividing by the appropriate power of 10. The prefixes and scaling factors can be found here:

So for example 1 hg (hectogram) = 100 g and 1 g = 100 cg (centigrams).

Therefore 1.9 hg = 190 g = 19,000 cg.

Use the same approach for the rest.
