How to convert milliliters to grams
Converting milliliters (ml) to grams (g) is a common task in chemistry, cooking, and scientific research. The conversion depends on the density of the substance you're measuring. Here's a step-by-step guide:
- Identify the substance you're measuring (water, alcohol, etc.)
- Find the density of the substance in grams per milliliter (g/ml)
- Multiply the volume in milliliters by the density to get grams
- For liquids, you can use the calculator below with standard densities
Note: The density of a substance varies with temperature and pressure. For precise measurements, always use the density value appropriate for your specific conditions.
Conversion formula
The basic formula for converting milliliters to grams is:
grams = milliliters × density (g/ml)
Where:
- grams = mass in grams
- milliliters = volume in milliliters
- density = mass per unit volume (g/ml)
For example, water has a density of 1 g/ml at standard conditions. Therefore, 15 ml of water would weigh 15 grams.
Worked example
Let's convert 15 ml of ethanol to grams. Ethanol has a density of approximately 0.789 g/ml.
grams = 15 ml × 0.789 g/ml = 11.835 grams
So, 15 ml of ethanol weighs approximately 11.84 grams.
FAQ
What is the difference between milliliters and grams?
Milliliters measure volume, while grams measure mass. The conversion between them depends on the density of the substance.
Can I convert milliliters to grams without knowing the density?
No, you need the density of the substance to make an accurate conversion. For common liquids, you can use standard density values.
Why does the density affect the conversion?
Density represents how much mass is contained in a given volume. Different substances have different densities, so the same volume can weigh different amounts.
What are common densities for liquids?
Water: 1 g/ml, Ethanol: 0.789 g/ml, Olive oil: 0.916 g/ml, Mercury: 13.594 g/ml.
