cc to Grams Converter
Convert cubic centimeters to grams using the substance's density. Because cc measures volume and grams measure weight, pick what you are measuring — water, milk, oil, flour, sugar, honey, salt, or a generic powder — then enter the cc.
Example: with Volume in cc (mL) 250 · Substance Granulated sugar (0.85 g/mL) → Weight: 212.5 g.
- In ounces (weight)7.50 oz
- How it converts250 cc × 0.85 g/mL = 212.5 g
Computed by the calculator below using its default values. Change any input to see your own numbers.
grams = cc × density (g/mL). cc equals mL, so only density separates volume from weight. Water is ~1 g/mL; most powders are lighter, honey and salt heavier.
Why you cannot convert cc to grams without density
A cubic centimeter is a fixed amount of space; a gram is a fixed amount of mass. To cross between them you need to know how tightly the material packs that space, which is its density in grams per milliliter (and cc equals mL). Water is the easy anchor at about 1 g/mL, so 100 cc of water is roughly 100 grams. Almost nothing else lands on 1.
Dry powders are the biggest surprise. Flour is only about 0.53 g/mL because it traps air, so 250 cc of flour weighs far less than 250 cc of water. Sugar sits near 0.85, honey is dense at about 1.42, and table salt around 1.22. That is why the substance selector matters — using water's density for a powder can be off by half.
How it’s calculated
Weight (g) = volume (cc) × density (g/mL), since 1 cc = 1 mL. Densities used: water 1.00, milk 1.03, cooking oil 0.92, all-purpose flour 0.53, granulated sugar 0.85, honey 1.42, table salt 1.22, generic powder 0.60 g/mL. Ounces (weight) use 1 oz = 28.3495 g.
Densities are approximate and vary with temperature, humidity, grind, and how packed a powder is (scooped vs sifted flour can differ 20 percent). Treat results as close estimates, not lab-grade weights.
Approximate densities (g per mL)
| Substance | Density | 250 cc weighs |
|---|---|---|
| Water | 1.00 | 250 g |
| Milk | 1.03 | 258 g |
| Granulated sugar | 0.85 | 213 g |
| Cooking oil | 0.92 | 230 g |
| All-purpose flour | 0.53 | 133 g |
| Honey | 1.42 | 355 g |
Densities are typical published values; computed as 250 cc × density.
Common mistakes
- Assuming cc equals grams — only true for water near 1 g/mL.
- Using one density for everything; flour and honey differ by nearly threefold.
- Packing or sifting a powder differently than the density assumes, shifting weight up to 20 percent.
- Confusing weight ounces here with fluid ounces of volume.
Frequently asked questions
How do I convert cc to grams?
Multiply the cc value by the substance's density in grams per milliliter, since cc equals mL. For example, 250 cc of granulated sugar at 0.85 g/mL is 250 × 0.85 = 212.5 grams.
Is 1 cc equal to 1 gram?
Only for water, which is about 1 gram per cc. Oil, flour, sugar, and honey all have different densities, so their cc-to-gram conversion is not one to one.
Why is flour so much lighter than water?
Flour is a powder that traps air, giving it a density near 0.53 g/mL. So 100 cc of flour weighs about 53 grams, roughly half of 100 cc of water.
How accurate is this for cooking or dosing?
It is a good estimate, but densities shift with temperature, humidity, and how packed the material is. For baking precision or any medication, weigh on a scale rather than convert from volume.
