Cubic Centimeters to Grams Calculator
1 cc (one cubic centimeter) of water weighs 1 gram. For any other substance, multiply the cubic centimeters by its density in g/cm³: 1 cc of honey weighs 1.42 g, 1 cc of granulated sugar about 0.84 g, and 1 cc of all-purpose flour about 0.51 g. Use the calculator below for liquids, baking powders and dry ingredients, or swap it to convert grams to cm³.
Key Facts: CC to Grams
- 1 cc = 1 cm³ = 1 mL. These are three names for the same volume.
- Grams = cubic centimeters × density (g/cm³).
- Cubic centimeters = grams ÷ density (g/cm³).
- 1 cc of water weighs 1 g, so for water the number of cc and grams is the same.
- Powders weigh less per cc than their solid material because air fills the gaps between grains. 1 cc of all-purpose flour weighs about 0.51 g.
How to Convert CC to Grams
To convert cubic centimeters to grams, you need one more number besides the volume, because a cubic centimeter measures volume and a gram measures mass. That number is density, the mass of one cubic centimeter of the substance. Multiply the volume by the density:
grams = cc x density (g/cm³)
Example 1, a liquid: 5 cc of honey, at a density of 1.42 g/cm³, weighs 5 × 1.42 = 7.1 grams.
Example 2, a powder: 5 cc of table salt, at a bulk density of 1.22 g/cm³, weighs 5 × 1.22 = 6.1 grams. The same 5 cc of all-purpose flour weighs only 2.55 grams, less than half as much, because flour is light and fluffy.
How to Convert Grams to cm³
To go the other way, divide the grams by the density:
cm³ = grams / density (g/cm³)
For water the answer is the same number, so 100 g of water fills 100 cm³. For anything else it is not: 100 g of granulated sugar fills about 119 cm³, 100 g of all-purpose flour about 196 cm³, and 100 g of honey only about 70 cm³. Press "Swap: Grams to CC" in the calculator to work in this direction.
Converting CC to Grams for Powders
To convert cc to grams for a powder, you need its bulk density: the mass of the powder divided by the total space it takes up, including the air between the grains. The United States Pharmacopeia (chapter 616) describes two versions. Bulk density is measured on powder poured loosely into a container. Tapped density is measured after the container has been tapped until the powder settles. Tapped density is always higher, often by 10 to 25 percent.
In practice, this means the same 5 cc measuring scoop can hold noticeably more powder if you press it down or shake it level. The values below assume powder spooned into the measure and leveled off, the method used by most recipe developers.
| Powder or dry ingredient | Density (g/cm³) | 1 cc | 5 cc | 15 cc | 100 cc |
|---|---|---|---|---|---|
| All-purpose flour | 0.51 | 0.51 g | 2.55 g | 7.65 g | 51 g |
| Almond flour | 0.41 | 0.41 g | 2.05 g | 6.15 g | 41 g |
| Granulated sugar | 0.84 | 0.84 g | 4.2 g | 12.6 g | 84 g |
| Brown sugar (packed) | 0.90 | 0.9 g | 4.5 g | 13.5 g | 90 g |
| Powdered sugar | 0.48 | 0.48 g | 2.4 g | 7.2 g | 48 g |
| Cocoa powder | 0.36 | 0.36 g | 1.8 g | 5.4 g | 36 g |
| Cornstarch | 0.47 | 0.47 g | 2.35 g | 7.05 g | 47 g |
| Nonfat dry milk powder | 0.47 | 0.47 g | 2.35 g | 7.05 g | 47 g |
| Baking powder | 0.81 | 0.81 g | 4.05 g | 12.15 g | 81 g |
| Baking soda | 1.22 | 1.22 g | 6.1 g | 18.3 g | 122 g |
| Table salt | 1.22 | 1.22 g | 6.1 g | 18.3 g | 122 g |
| Kosher salt (Diamond Crystal) | 0.54 | 0.54 g | 2.7 g | 8.1 g | 54 g |
| Kosher salt (Morton) | 1.08 | 1.08 g | 5.4 g | 16.2 g | 108 g |
| Rolled oats | 0.38 | 0.38 g | 1.9 g | 5.7 g | 38 g |
Two rows show how much powder density can vary within one ingredient. Diamond Crystal and Morton are both kosher salt, but Diamond Crystal's hollow, flaky crystals weigh half as much per cc as Morton's denser granules. Swap one for the other by volume and a recipe ends up twice as salty or half as salty.
For supplements and other powders sold with a measuring scoop, use the grams printed on the label rather than any density here. Scoops are often sized in cc (1, 5 or 10 cc are common), but the manufacturer's stated serving weight already accounts for that particular powder. When accuracy matters, for baking ratios, lab work or anything you dose, weigh the powder on a scale instead of measuring by volume.
CC to Grams Chart for Liquids
Liquids are far more consistent than powders, because they have no air gaps and pack the same way every time:
| Cubic centimeters | Water | Milk | Vegetable Oil | Honey |
|---|---|---|---|---|
| 1 cc | 1 g | 1.03 g | 0.92 g | 1.42 g |
| 5 cc | 5 g | 5.15 g | 4.6 g | 7.1 g |
| 10 cc | 10 g | 10.3 g | 9.2 g | 14.2 g |
| 25 cc | 25 g | 25.75 g | 23 g | 35.5 g |
| 50 cc | 50 g | 51.5 g | 46 g | 71 g |
| 100 cc | 100 g | 103 g | 92 g | 142 g |
| 250 cc | 250 g | 257.5 g | 230 g | 355 g |
| 500 cc | 500 g | 515 g | 460 g | 710 g |
| 1,000 cc | 1,000 g | 1,030 g | 920 g | 1,420 g |
Why 1 cc of Water Weighs 1 Gram
The match is by design. When the metric system was created in France in the 1790s, the gram was defined as the mass of one cubic centimeter of water. The definitions have since been refined, and today the kilogram is fixed by a physical constant rather than by water, but the original relationship still holds to within a fraction of a percent.
Strictly, water's density changes slightly with temperature. It peaks at 0.99997 g/cm³ near 4 °C and is about 0.998 g/cm³ at a room temperature of 20 °C. That difference is 2 milligrams per cc, far smaller than a kitchen scale can detect, so this calculator uses 1.0 g/cm³ for water.
CC, cm³, cm3 and mL Are the Same Volume
A cubic centimeter is the volume of a cube 1 cm on each side. Scientists write it cm³, people typing without a superscript write cm3, and medicine, engines and measuring scoops label it cc. A milliliter is defined as exactly the same volume, so 1 cc = 1 cm³ = 1 mL, and every conversion on this page works the same for milliliters.
Common Questions
Is 1 cc equal to 1 gram?
Only for water and liquids with the same density as water. A cc is a unit of volume and a gram is a unit of mass, so they can only be equal when one cubic centimeter of the substance happens to weigh one gram. Water does, which is why the two are often treated as interchangeable. Most other substances do not: 1 cc of vegetable oil weighs 0.92 g, 1 cc of honey weighs 1.42 g, and 1 cc of all-purpose flour weighs only about 0.51 g.
How many grams is 1 cc of powder?
It depends on the powder, and the range is wide. Light, fluffy powders such as cocoa weigh about 0.36 g per cc, flour about 0.51 g, granulated sugar about 0.84 g, and fine table salt about 1.22 g. These figures assume the powder is spooned into the measure and leveled. Packing it down or tapping the container makes the powder settle, so more of it fits in the same cc and the weight can rise by 10 percent or more.
How do I convert grams to cm3?
Divide the grams by the density of the substance in g/cm³. For water, the density is 1, so the number stays the same and 250 g of water fills 250 cm³. For olive oil, at 0.91 g/cm³, 250 g fills about 275 cm³. For granulated sugar, at 0.84 g/cm³, 250 g fills about 298 cm³. If you do not know the density, look it up for your exact substance, or use the calculator's swap button with one of the listed ingredients.
How many grams are in 5 cc?
Five cc of water weighs 5 grams. Five cc is also the volume of a metric teaspoon, so it is a useful reference point for other substances. The same 5 cc holds about 7.1 g of honey, 6.1 g of table salt, 4.2 g of granulated sugar, and about 2.55 g of all-purpose flour. The spread shows why converting between cc and grams needs the density of the specific substance, not just the volume.
Why does a scoop of powder weigh differently each time?
Because a powder's volume includes the air between its grains, and that air changes with every scoop. Powder that has settled in transport, been pressed into the scoop, or been shaken level packs more tightly and weighs more. Freshly fluffed or sifted powder weighs less. Humidity and clumping add more variation. For results you can repeat, scoop the same way every time, or better, weigh the powder on a digital scale.
