### Metric Conversion Special Note

Return to Metric Conversions

Here are two examples of conversion problems:

Convert 5000 cubic centimeters to mL
Convert 3.5 L to cubic centimeters

These are of a type of conversion often seen. Cubic centimeters (cm^{3}) is a non-SI unit, but it is in widespread use.

So, here is the rule to memorize:

one cm^{3} = one mL

Pretty easy rule to remember, but many students forget it and teachers do like to do two things:

1) Never mention this conversion in class.

2) Then, ask this type of conversion on tests.

Here is the answer for the first problem:

5000 cm^{3} = 5000 mL

You can think of the second problem becoming "convert 3.5 L to mL," The answer of which is 3500 mL. Then, replace mL with cm^{3} and the problem is complete. The answer then becomes:

3.5 L = 3500 cm^{3}

Hopefully that was pretty easy. Just remember, it stands a decent chance of (1) not being mentioned and (2) being on the test.

Oops, one other conversion to remember:

1 dm^{3} = 1 L

dm^{3} is called 'cubic decimeter.
