1. What is Methane Gas Density Calculator?

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

Purpose: It helps scientists, engineers, and students working with methane gas to convert between different density units.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \rho \) — Density in grams per milliliter (g/mL)
• \( \rho_{kg/m³} \) — Density in kilograms per cubic meter (kg/m³)

Explanation: Since 1 kg/m³ equals 0.001 g/mL, we divide the kg/m³ value by 1000 to convert to g/mL.

3. Importance of Methane Density Calculation

Details: Knowing methane's density is crucial for storage, transportation, combustion calculations, and safety considerations in industrial applications.

4. Using the Calculator

Tips: Enter the methane density in kg/m³ (default 0.717 kg/m³ for STP). The value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's the density of methane at STP?
A: At standard temperature and pressure (STP), methane has a density of about 0.717 kg/m³ or 7.17 × 10⁻⁴ g/mL.

Q2: Why convert between kg/m³ and g/mL?
A: Different scientific fields and applications use different units, and conversions are often needed for calculations and comparisons.

Q3: How does temperature affect methane density?
A: Methane density decreases with increasing temperature (at constant pressure) according to the ideal gas law.

Q4: What's the difference between density and specific gravity?
A: Density is mass per unit volume, while specific gravity is the ratio of a substance's density to water's density at 4°C.

Q5: Where is methane density information used?
A: In natural gas processing, chemical engineering, environmental studies, and energy production calculations.
