Conversion Formula:
From: | To: |
The conversion from grams to milliliters depends on the density of the substance. Since different materials have different densities, 20 grams of one substance may occupy a different volume than 20 grams of another substance.
The calculator uses the conversion formula:
Where:
Explanation: The formula converts mass to volume using the substance's density, which represents mass per unit volume.
Details: Density is a critical factor when converting between mass and volume. Without knowing the density, accurate conversion between grams and milliliters is not possible as different substances have different mass-to-volume ratios.
Tips: Enter the density of the substance in g/ml. The density must be greater than zero. Common densities: water = 1 g/ml, milk ≈ 1.03 g/ml, honey ≈ 1.42 g/ml.
Q1: Why can't I convert grams to ml without density?
A: Because grams measure mass while milliliters measure volume. The relationship between mass and volume depends on the substance's density.
Q2: Is 20 grams always equal to 20 ml?
A: Only for water at standard temperature and pressure (density = 1 g/ml). For other substances, the volume will be different.
Q3: Where can I find density values for common substances?
A: Density tables are available in chemistry references, material safety data sheets, and online databases for various materials.
Q4: Does temperature affect density?
A: Yes, density changes with temperature. Most substances expand when heated, decreasing density. Water is unique with maximum density at 4°C.
Q5: Can I use this for any substance?
A: Yes, as long as you know the accurate density of the substance at the given conditions (temperature, pressure, concentration).
