mL to Grams Calculator
Convert milliliters to grams using substance density. The conversion depends on what substance you are measuring — 1 mL of water weighs 1 gram, but other liquids differ. Perfect for cooking and science.
How to Convert mL to Grams
- Identify the substance and find its density in g/mL.
- Multiply the volume in milliliters by the density.
- The result is the mass in grams.
Formula
Grams = mL × Density (g/mL)
Example Calculation
Convert 250 mL of cooking oil to grams:
Density of cooking oil = 0.92 g/mL
Mass = 250 mL × 0.92 g/mL = 230 grams
Substance Density Reference Table
| Substance | Density (g/mL) | 100 mL = 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 mL equal to 1 gram?
Only for water. 1 mL of water weighs approximately 1 gram. Other substances have different densities, so 1 mL may weigh more or less than 1 gram.
How many grams is 100 mL of milk?
Whole milk has a density of about 1.03 g/mL, so 100 mL of milk weighs approximately 103 grams.
How do I convert mL to grams for honey?
Honey has a density of about 1.42 g/mL. Multiply the mL by 1.42. For example, 50 mL of honey = 50 × 1.42 = 71 grams.
Can I use this for dry ingredients?
Yes, if you know the bulk density of the dry ingredient. However, dry ingredients can vary in density depending on how tightly they are packed.
What is the difference between mL and grams?
Milliliters (mL) measure volume — how much space something takes up. Grams (g) measure mass — how heavy something is. They are related through density.
