Cubic Centimeters to Grams Converter

Reading a volume in cubic centimeters and want the weight in grams? For water the two are the same number, so enter the cc below. This assumes water, at a density of 1 g/mL.

Result100 cc = 100 g
Quick answer
A cubic centimeter and a milliliter are the same volume, and one cc of water weighs 1 gram. So 100 cc of water is 100 g and 250 cc is 250 g. This one-to-one match holds only for water. Oil is lighter, so a cc weighs about 0.91 g, while honey is heavier at roughly 1.42 g per cc, because their density differs from water.

How to convert cc to Grams

grams = cc × densitywater density = 1 g/mL, so grams = cc · reverse: cc = grams ÷ density
cc
the volume in cubic centimeters
grams
the weight of that volume of water
density
grams per cc, taken as 1 for water

One cubic centimeter equals one milliliter exactly, so cc and mL are interchangeable as volume units.

The one-to-one figure assumes water. For a different liquid, multiply the cc by that liquid's density in g/mL: oil near 0.91, milk about 1.03, honey around 1.42.

Frequently asked questions

Is 1 cc equal to 1 gram?

For water, yes. One cc of water weighs 1 g. Other substances weigh more or less because their density is not 1.

How many grams is 100 cc?

For water, 100 cc is 100 g.

Is a cc the same as a mL?

Yes. One cubic centimeter and one milliliter are the same volume.

How many grams is 50 cc of oil?

About 45.5 g, since cooking oil has a density near 0.91 g/mL rather than water's 1.

Why does the substance matter?

A cc measures space, a gram measures weight, and density links them. Only water gives an exact one-to-one match.
