1. What is Density of Water in kg/L?

Definition: This calculator converts the density of water from kg/m³ to kg/L (kilograms per liter).

Purpose: It helps in understanding and converting water density measurements between different units.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ \rho = \frac{\rho_{kg/m³}}{1000} \]

Where:

\( \rho \) — Density in kg/L
\( \rho_{kg/m³} \) — Density in kg/m³

Explanation: Since 1 m³ = 1000 liters, dividing kg/m³ by 1000 converts it to kg/L.

3. Importance of Water Density

Details: Water density is crucial in various scientific, engineering, and everyday applications. Pure water has a density of ~1 kg/L at 4°C.

4. Using the Calculator

Tips: Enter the density in kg/m³ (default 1000 kg/m³ for water at 4°C). The value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's the density of water at room temperature?
A: About 0.998 kg/L (998 kg/m³) at 20°C.

Q2: Why does water density change with temperature?
A: Water density peaks at 4°C (1.000 kg/L) due to hydrogen bonding and molecular structure.

Q3: How does salinity affect water density?
A: Seawater is denser (~1.025 kg/L) due to dissolved salts.

Q4: What's the practical use of this conversion?
A: Essential for fluid mechanics, hydrology, chemistry, and any work involving liquid measurements.

Q5: How precise is this conversion?
A: Mathematically exact since 1 m³ = exactly 1000 liters.
