Is there an appreciable difference between cc and ml ?
My acid test kit contains a 12cc and 20cc syringe. Instructions call for titration of 15cc wine with 10cc .2 Sodium Hydroxide Books I have use ml in their tests. I presume the result is the same whichever measure is used. I can't find a reference that compares cc / ml. Just wondering.

They are one and the same

It's the simple things we stumble over -- and are so often embarrassed to ask about. ;o) Ray
Thanks Ray. Yes, the simple things. Without thinking about it very much I was having difficulty equating One-HUNDREDTH of a METER (cubic) with One-THOUSANDTH of a LITRE (a relatively large part of a big thing with a ralatively small part of a smaller thing) But, looking at my desk ruler, of course it does. LOL

Lest anyone become confused by this... one cc is not 1/100 of a cubic meter. :-)
Right. It's one _millionth_ of a cubic meter.

Right. And a liter is a cubic deciliter or 1/10 meter * 1/10 meter *
1/10 meter, or 1/1,000 of a cubic meter. So it should be obvious that 1/1,000 of a liter ( milliliter), is therefore 1/1,000,000 of a cubic meter ! ;-)I knew high school Chemistry would be good for something.
LOL !!! I was eye-balling, on my desk ruler, the volume that would be displaced by 1cm X 1cm X 1cm. (1cc). Looks sort of the same a 1ml... Hey! NOT 1/100 of a cubic meter. But, I guess, if we titrate 15/100 of a cubic meter of wine with
10/100 of a cubic meter of Sodium Hydroxide we will get the same result. Hmmm. Hard to measure those large volumes. Maybe that is why they use15cc/15ml and 10cc/10ml ...Cheers,

sorry it appears mixed up on the posting
To convert CC cubic centimeters to Milliliters Multiply by 0.999972. eg 12 cc = 11.999664 ml as near as dam it 12 Stephen
Wrong. You multiply by 1.000. A liter is by definition 1000 cc.
It's not just the appearance that's mixed up.
Still wrong. 12 cc = 12 ml. A liter is 1000 cc by definition and therefore 1 ml and 1 cc are *exactly* the same.
Here's an interesting historical reference about the number .999972.
I learn something new everyday.
Well, not quite. A liter is a cubic decimeter not a cubic deciliter. You cannot cube a deciliter as it is a volume to begin with.
If you think about this stuff too much you will just confuse yourself.
Ray
Ya know Ray, you're absolutely right. I should have said "cubic decimeter". It's things like that that keep us humble. Well, me anyway.

There is no mix up I attempted to send the information direct but alas your e-mail systems returned my response to you.
The density hangs with the water, like also with other materials, off of the temperature and of the pressure.
In addition solved materials play a role:
Also in entmineralisiertem water gases are normally solved, since the water is constant under normal conditions with air in contact.
Density of pure, air-free water with normal print (101300 Pa ("Pascal"), 1013 mbar) between 0 and 100 °C in kg/m³:
Temp.(°C) D(kg/m³)
0 999.841 999.90
2 999.943 999.96
4 999.975 999.96
10 999.7015 999.10
20 998.2125 997.05
30 995.6535 994.04
40 992.2245 990.22
50 988.0555 985.70
60 983.2165 980.57
70 977.7975 974.86
80 971.8385 968.62
90 965.3295 961.89
100 958,35The table codes can be converted as follows into other units:
Table code/1000 = value in kg/dm³ table code * 0.001000028 = value in kg/l or g/ml (or: Table code/999.972 = value in kg/l or g/ml)
Dependence the waterproof one on the pressure is relatively small.
1 bar each (= 100000 Pa) increase in pressure increases the density by approx. 0.046 kg/m³ (applies up to approx. 50 bar).Normal air pressure fluctuations have no influence on the density of the water therefore practically.

This is all very interesting, I'm sure, but it's also completely irrelevant.
The _original_ definition of a liter was that volume of water at a specific temperature having a mass of one kilogram. But the definition was changed _over_forty_years_ago_. A liter is now _by_definition_ 1000 cc and therefore 1 cc and 1 ml are _absolutely_ identical.
| >There is no mix up I attempted to send the information direct but alas | >your e-mail systems returned my response to you. | >
One liter at 4 C is the same volume as one liter at 99 C or at any other temperature.
A liter is a liter, regardless of the temperature or the substance being measured. You don't seem to grasp this essential point: the definition of a liter no longer references (and has not referenced for many years) the volume of a specified mass of water at a specified temperature. It _used_ to, but not any more, not for a long time.
A liter is _by_definition_ one thousand cubic centimeters. Period.
Therefore 1 milliliter and 1 cubic centimeter are _absolutely_ identical. At all temperatures. At all pressures. For all substances.
