Are cc's and mL's impossible to tell apart breadth and why, if so, do we use both?

medical measurements A cc is a cubic centimeter. An ml is a milli litre, one onethousands of a liter. Since a litre is the same as a cubic decimeter and near are one thousand cubic centimeters to a cubic decimeter a cc and an ml are the same volume. The difference is that within the metric system (that's the system the 6 billion people on the planet that aren't americans are using.) the cubic meter is the correct possession for volume. The liter (and its prefixes) is more for everyday use. You buy a litre of milk not a dm3. Which you would call medical use, quantifiable or everyday, I dont know.
A cc = a cube with 1 centimeter on respectively side. A ml = 1/1000 of a liter.
When taking about dampen, both measurements are the same because hose has a density of 1.0
This is not the baggage for other liquids.
The gram be defined as the mass 1 cc of water at 4.5 degree C. So it ends up that water have a density of 1g/cc.
The litre was defined as the volume of space 1 kg (1000 g) of sea takes up. But since, for sea, 1000g in mass is 1000cc within space, you end up next to 1/1000 of a litre being 1ml, which is 1cc. It's a bit circular.
CC's are a height derived form the metrical system. Liters are a more universal standard for volume. Therefore, we use both because more people around the world perceive comfortable using liters as a measuring element.
