What is the difference in between a “cc” and “ml”?

### Larry’s Response:

Well, it’s a long, convoluted story that usually ends with, “that’s the way it is”, or “just because”.

You are watching: What does cc stand for in measurement

Before comparing and also contrasting cc and also ml, additionally be mindful that gm can be component of the mix (or “mix up” if you want to consider it the way).

cc way cubic centimeter, a measure up of volume (one-centimeter x one-centimeter, x one centimeter is one centimeter to the 3rd power, or one centimeter cubed… cubic centimeter)ml (or mL) typical milliliter (on one-thousandths that a liter), additionally a measure of volumegm (of Gm) way gram, a unit the weight

The choice to usage cc or ml is often dictated by locality and also convention. In the metric system it is a convention to talk about liquids, for example, in volumes of liters – and also parts the liters. Human being in metric areas will purchase their petrol in liters and they frequently report their fuel efficiency as kilometers per liter – while areas that execute not abide by the metric standards will describe gasoline in gallons and distance together miles. Those folks report fuel efficiency as miles per gallon. In the last analysis, over there is certain no difference between a cc and a ml. They space perfectly interchangeable interchangeable – other than for convention. When a person may placed a liter of gasoline in your car, they more than likely wouldn’t call it a cubic decimeter (dm cubed) – also though both stand for the exact same amount.

Hard things are, vice versa, usually described as cubic centimeters or cubic meters; 1 cubic meters of concrete, for example.

### Identical?

Some definitions cite that a cc and a ml are virtually identical. Let’s simply agree that they are identical and use castle that way and interchangeably. Basically, use everything makes you comfortable; cc or ml.

The gm (or Gm) issue complicates points a bit since many of united state think that a Gm is the exact same as a cc, which I’ve just asserted is the same as a ml. This is 100% precise if we room measuring water in ~ a particular temperature and also barometric pressure. The gram is officially defined as the fixed 1 cc (ml) that water in ~ 4.5 levels C in ~ sea level. For this reason it end up that water has actually a thickness of 1gm/cc or 1gm/ml – additionally referred come as particular gravity.

Temperature and barometric pressure impacts the massive of many things, including water. As temperatures fall and also water freezes it will certainly float in fluid water since frozen water has less mass 보다 liquid water. A gram of ice cream – weighed on a range at sea level – will certainly contain much more volume 보다 a gram the water – yet there will be less water in the gram of ice cream after that melts. However, the distinction is an extremely small. Therefore, for every intents and purposes – because we usually deal with items in ~ room temperature – one gram the water is embraced as equivalent to a cc and also a ml that water even though we recognize that it isn’t true. The level of error is insignificant.

Not every item gift the exact same mass every volume as water. Mercury is a heck of a lot of heavier 보다 water. One ml or cc the mercury would certainly weigh 13.56 times as much as a comparable volume that water. This is all settled when feather at specific gravity, i beg your pardon is expressed in mass every volume (water is 1, definition one gram in one cc or ml).

A human who needs absolute accuracy would never equate the volume that a product (cream, gel, liquid, etc) through a an easy mass. However, for every intents, a gram the a cream is virtually the same as a ml or cc that it. The difference in between the details gravity (sg) that a cream and water is tiny, yet the definition magnifies as the amounts increase. Because that example, a cream through a sg 0.95 would certainly be 0.95gm in ever ml or cc – not much of an error, despite it would float in water (which has actually a sg the 1). But, practically, one order because that 1 gram that a cream might be successfully represented by 1 cc or 1 ml. A trouble arises when the quantities increase and also teh complete variance becomes noticeable.
