1. What is Natural Gas Density Conversion?

Definition: This calculator converts the density of natural gas from kg/m³ to g/cm³.

Purpose: It helps engineers and scientists work with natural gas density in different unit systems.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \rho \) — Density in g/cm³
• \( \rho_{kg/m³} \) — Density in kg/m³

Explanation: Since 1 g/cm³ equals 1000 kg/m³, we divide the kg/m³ value by 1000 to get the equivalent in g/cm³.

3. Importance of Natural Gas Density

Details: Natural gas density affects flow calculations, storage requirements, and energy content measurements.

4. Using the Calculator

Tips: Enter the natural gas density in kg/m³ (default 0.7 kg/m³, which is typical for natural gas at STP). Value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's the typical density range for natural gas?
A: Natural gas typically has a density of 0.0007–0.0009 g/cm³ (0.7–0.9 kg/m³) at standard temperature and pressure (STP).

Q2: Why convert between these units?
A: Different scientific and engineering applications use different unit systems, and conversions are often needed.

Q3: How does temperature affect natural gas density?
A: Density decreases with increasing temperature (inverse relationship) according to the ideal gas law.

Q4: What's the difference between density and specific gravity?
A: Specific gravity compares the gas density to air density (1.225 kg/m³ at STP), while density is absolute.

Q5: How does composition affect natural gas density?
A: Heavier hydrocarbons (like propane) increase density, while methane-rich gas is less dense.
