1. What is Water Volume to Mass Conversion?

The conversion between milliliters (mL) and grams (g) for water is based on water's density. At standard temperature and pressure (STP), 1 mL of water equals 1 gram.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( mL \) — Volume in milliliters
• \( g \) — Mass in grams

Explanation: This conversion works because water has a density of 1 g/mL at standard conditions (4°C, 1 atm).

3. Importance of Water Conversion

Details: Converting between volume and mass is essential in cooking, chemistry, medicine, and many scientific applications where precise measurements are required.

4. Using the Calculator

Tips: Enter water volume in mL. The calculator assumes pure water at standard conditions (4°C). For other temperatures or substances, different conversion factors apply.

5. Frequently Asked Questions (FAQ)

Q1: Is this conversion exact for all water?
A: The 1:1 ratio is exact for pure water at 4°C. At room temperature, it's approximately the same (0.998 g/mL at 20°C).

Q2: Does this work for other liquids?
A: No, other liquids have different densities. For example, 1 mL of milk ≈ 1.03 g, 1 mL of oil ≈ 0.92 g.

Q3: What about saltwater or other solutions?
A: Solutions with dissolved substances will be denser. For saltwater, 1 mL ≈ 1.02-1.03 g depending on salinity.

Q4: Why is water's density 1 g/mL?
A: The metric system was designed this way - 1 gram was originally defined as the mass of 1 cubic centimeter (1 mL) of water at its maximum density.

Q5: How does temperature affect the conversion?
A: Water density changes with temperature (0.99997 g/mL at 0°C, 0.997 g/mL at 25°C, 0.958 g/mL at 100°C).
