1. What is Water Density?

Definition: Water density (ρ) is the mass per unit volume of water, typically measured in kilograms per cubic meter (kg/m³).

Standard Value: Pure water at 4°C has a density of exactly 1000 kg/m³.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \rho \) — Density (kg/m³)
• \( m \) — Mass (kg)
• \( V \) — Volume (m³)

Explanation: The mass of water is divided by its volume to determine its density.

3. Importance of Water Density Calculation

Details: Understanding water density is crucial for engineering, chemistry, hydrology, and many industrial processes.

4. Using the Calculator

Tips: Enter the mass of water in kilograms and volume in cubic meters. Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What affects water density?
A: Temperature is the main factor - water density decreases as temperature increases (above 4°C).

Q2: What's the density of seawater?
A: Seawater is denser (about 1020-1050 kg/m³) due to dissolved salts.

Q3: How precise is this calculator?
A: It provides theoretical values. For precise measurements, consider temperature and purity.

Q4: Why does ice float on water?
A: Ice is less dense (about 917 kg/m³) than liquid water due to its crystalline structure.

Q5: What units should I use?
A: The calculator uses kg for mass and m³ for volume, but can convert from other units if needed.
