Forum rules
Dear convert-me.com forum visitors,
Our forum has been available for many years. In September 2014 we decided to switch it to read-only mode. Month after month we saw less posts with questions and answers from real people and more spam posts. We were spending more and more resources cleaning the spam until there were less them 1 legitimate message per 100 spam posts. Then we decided it's time to stop.
All the posts in the forum will be available and searchable. We understand there are a lot of useful information and we aren't going to remove anything. As for the new questions, you can always ask them on
convert-me.com FaceBook pageThank you for being with us and sorry for any inconveniences this could caused.

How do you prove that 1 ml = 1 cc?
Is it true for water only or any other liquid?

I go to NIST SP330 (the US version of the SI brochure) and read the declaration of the 12th CGPM, 1964, in Resolution 6 that the liter is a special name for the cubic decimeter. Since ther are 10 cm in a dm, when cubed there are 1000 cm^3 in 1 dm^3 or 1 L. ! mL = 1/1000 L = 1 cm^3.
(Note that from 1901 to 1964,it was the volume occupied by 1 kg of water at maximum density (about 4 degrees C), as declared in 3rd CGPM, 1901. This is about 1.000028 dm^3. The confusion led to a review from 1960 to 1964.
Both the liter and cubic centimer are units of volume. It doesn't matter what substance.
