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

Definition: This calculator converts the density of hydrogen gas from kg/m³ to kg/L.

Purpose: It helps scientists and engineers work with hydrogen density in different unit systems for various applications.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

Explanation: Since 1 m³ = 1000 L, we divide the kg/m³ value by 1000 to convert to kg/L.

3. Importance of Hydrogen Density Calculation

Details: Understanding hydrogen density is crucial for fuel storage, transportation, and various industrial applications.

4. Using the Calculator

Tips: Enter the density in kg/m³ (default value 0.0899 kg/m³ for hydrogen at STP). The value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is the density of hydrogen at STP?
A: At standard temperature and pressure (STP), hydrogen has a density of about 0.0899 kg/m³ or 8.99 × 10⁻⁵ kg/L.

Q2: Why convert between kg/m³ and kg/L?
A: Different applications use different units - kg/m³ is common in physics while kg/L is often more practical for engineering.

Q3: How does temperature affect hydrogen density?
A: Density decreases with increasing temperature (at constant pressure) following the ideal gas law.

Q4: What's the density of liquid hydrogen?
A: Liquid hydrogen at -253°C has a density of about 70.8 kg/m³ (0.0708 kg/L).

Q5: How does this compare to air density?
A: Hydrogen is much less dense than air (about 1/14th the density of air at STP).
