### Converting Cubic Centimeters

How do I convert cc's to milliliters or decaliters?  For instance, if
I fill a syringe with 10 cc's of something, how many milliliters will
I have?  I cannot find the answer anywhere and would appreciate your
help. (I volunteer teach for one of the online services.)

Thank you.

Hi, Jacqueline, greetings from another volunteer!

It is very easy to convert cubic centimeters (cc) to milliliters: they
are exactly the same thing.

The cc is not the correct abbreviation any more, however, under the SI
(Systeme International, the official metric system). We are supposed
to use cm^3 (centimeters cubed) instead, but of course cc's don't go
away that easily.

The liter is not part of the SI either, but it is tolerated because
it is more convenient to use than the official cubic meter.

1 l = 1 dm   (cubic decimeter)

3
1 ml = 1 cm  (cubic centimeter)

I wonder if you meant deciliters instead of decaliters. A decaliter
(dal) is 10 liters, while a deciliter (dl) is 1/10 liter. This
potential confusion is one reason I would avoid this unit. The
following Web site, one of several good references on the metric
system (SI), says that the only prefixes authorized to be used with
liters are milli- and micro-.
