Metric System Conversions

I need to be able to convert between kilo, centi, milli, micro.

Can you please give me examples and explanations

I get some problems right but some I get wrong.
For example my teacher had this problem 5.5 kg = 5500000000 mcg
Can you explain this problem also.

Please see the attached file for the complete solution.

Here are the rules of conversion:

To convert from a larger unit to a smaller unit, we multiply.

For example, since 1 Kg = 1000 grams, to convert 5 kg into grams we multiply:

5 × 1000 = 5000 grams

To convert from a smaller unit to a larger unit, we divide.

For example, since 1 Kg = 1000 grams, to convert 5000 grams ...

Metric system conversions are discussed in the solution.
