cc to Grams Calculator
Convert cubic centimeters (cc) to grams using substance density. Since 1 cc = 1 mL, this conversion works the same as mL to grams. The density determines how heavy each cc of substance is. Common in medical dosing and engine displacement.
How to Convert cc to Grams
- Note that 1 cc (cubic centimeter) = 1 mL.
- Find the density of the substance in g/cc (same as g/mL).
- Multiply the volume in cc by the density to get grams.
Formula
Grams = cc × Density (g/cc)
Note: 1 cc = 1 mL
Example Calculation
Convert 50 cc of honey to grams:
Density of honey = 1.42 g/cc
Mass = 50 cc × 1.42 g/cc = 71 grams
Substance Density Reference Table
| Substance | Density (g/cc) | 100 cc = grams |
|---|---|---|
| Water | 1 | 100.00 g |
| Milk (whole) | 1.03 | 103.00 g |
| Cooking Oil | 0.92 | 92.00 g |
| Honey | 1.42 | 142.00 g |
| Gasoline | 0.75 | 75.00 g |
Frequently Asked Questions
Is 1 cc the same as 1 mL?
Yes, 1 cubic centimeter (cc) is exactly equal to 1 milliliter (mL). They are interchangeable units of volume.
Is 1 cc equal to 1 gram?
Only for water. 1 cc of water weighs 1 gram. For other substances, the weight depends on density. 1 cc of honey weighs 1.42 grams.
What does cc mean in medicine?
In medicine, cc (cubic centimeter) is used to measure liquid volumes, especially for injections and IV fluids. It is equivalent to 1 mL.
How do I convert cc to grams for engine oil?
Engine oil typically has a density of about 0.87 g/cc. Multiply the cc by 0.87 to get grams. For example, 1000 cc of engine oil ≈ 870 grams.
What is the difference between cc and cm³?
There is no difference. cc (cubic centimeter) and cm³ are the same unit. Both equal 1 mL of volume.
Solved Examples
Example 1: Convert 250 cc of olive oil to grams
Solution:
Step 1: Identify density of olive oil = 0.92 g/cc
Step 2: Apply formula: grams = cc × density
Step 3: grams = 250 × 0.92 = 230
Answer: 250 cc of olive oil = 230 grams
Example 2: Convert 100 cc of honey to grams
Solution:
Step 1: Identify density of honey = 1.42 g/cc
Step 2: Apply formula: grams = cc × density
Step 3: grams = 100 × 1.42 = 142
Answer: 100 cc of honey = 142 grams
Example 3: Convert 500 cc of mercury to grams
Solution:
Step 1: Identify density of mercury = 13.6 g/cc
Step 2: Apply formula: grams = cc × density
Step 3: grams = 500 × 13.6 = 6800
Answer: 500 cc of mercury = 6,800 grams (6.8 kg)
Example 4: Convert 200 cc of milk to grams
Solution:
Step 1: Identify density of whole milk = 1.03 g/cc
Step 2: Apply formula: grams = cc × density
Step 3: grams = 200 × 1.03 = 206
Answer: 200 cc of milk = 206 grams

Common Mistakes to Avoid
The most frequent error when converting cc to grams is assuming all substances have a density of 1 g/cc. This only applies to water. Many people incorrectly treat cc and grams as interchangeable for any liquid, but 100 cc of honey weighs 142 grams while 100 cc of oil weighs only 92 grams. Another common mistake is confusing mass (grams) with volume (cc/mL) — they are different physical quantities connected only through density. Temperature also affects density: water at 4°C has a density of exactly 1.000 g/cc, but at 80°C its density drops to about 0.972 g/cc. For powdered substances like flour, density varies significantly depending on whether the material is loosely scooped or tightly packed — all-purpose flour ranges from about 0.52 to 0.63 g/cc depending on packing.
Key Takeaways
- The core formula is: grams = cc × density (g/cc)
- 1 cc is exactly equal to 1 mL — these units are fully interchangeable
- Only water has a density of 1 g/cc (at standard conditions), making cc = grams true only for water
- Substances denser than water (honey, mercury, milk) weigh more than 1 gram per cc
- Substances lighter than water (oil, gasoline, ethanol) weigh less than 1 gram per cc
- Always check whether a density value refers to packed or loose material, especially for powders and granular substances
