Grams to Milliliters Formula:
| From: | To: |
The conversion from grams to milliliters depends on the density of the substance. Since grams measure mass and milliliters measure volume, density serves as the conversion factor between these two units of measurement.
The calculator uses the fundamental formula:
Where:
Explanation: This formula converts mass to volume using the substance's density, which represents the mass per unit volume.
Details: Density is crucial because different substances have different densities. For example, water has a density of 1 g/mL, while other substances like oil or mercury have different densities, making accurate conversion impossible without knowing the specific density.
Tips: Enter the mass in grams and the density in g/mL. Both values must be positive numbers. The density must be greater than zero for the calculation to be valid.
Q1: Why can't I directly convert grams to milliliters?
A: Grams measure mass while milliliters measure volume. The conversion requires density because the same mass of different substances occupies different volumes.
Q2: What is the density of water?
A: Pure water has a density of approximately 1 g/mL at 4°C, which is why 1 gram of water equals 1 milliliter.
Q3: How do I find the density of a substance?
A: Density can be found in reference tables, material safety data sheets, or measured by dividing the mass of a known volume by that volume.
Q4: Does temperature affect density?
A: Yes, density changes with temperature. Most substances expand when heated, decreasing their density. Always use density values at the appropriate temperature.
Q5: Can I use this for all substances?
A: This formula works for homogeneous substances. For mixtures or solutions, you may need to calculate effective density based on composition.
