1. What is Oxygen Gas Density?

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

Purpose: It helps scientists, engineers, and students work with oxygen 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: 1 kg/m³ equals 0.001 g/cm³, so we divide the kg/m³ value by 1000 to convert to g/cm³.

3. Importance of Oxygen Density

Details: Oxygen gas density is crucial for chemical engineering, respiratory calculations, and various industrial processes.

4. Using the Calculator

Tips: Enter the oxygen density in kg/m³ (default 1.43 kg/m³ for STP). The value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's the density of O₂ at STP?
A: Approximately 1.43 kg/m³ or 0.00143 g/cm³ at standard temperature and pressure (0°C, 1 atm).

Q2: How does temperature affect oxygen density?
A: Density decreases as temperature increases (at constant pressure) according to the ideal gas law.

Q3: Why convert between these units?
A: Different scientific fields use different units - chemistry often uses g/cm³ while engineering uses kg/m³.

Q4: How does oxygen density compare to air?
A: Oxygen is slightly denser than dry air (1.29 kg/m³ at STP).

Q5: What about other pressure conditions?
A: Density increases linearly with pressure at constant temperature.
