Gas Volume Converter

Our Gas Volume Converter uses the ideal gas law (PV = nRT) to provide accurate conversions between pressure, volume, temperature, and moles. Whether you're working with different pressure units, volume units, or temperature scales, this tool delivers precise results instantly.

Supported Unit Categories:

  • Pressure Units: Pascals, bars, atmospheres, PSI, mmHg, torr, and more
  • Volume Units: Liters, cubic meters, cubic feet, gallons, milliliters, and more
  • Temperature Units: Kelvin, Celsius, Fahrenheit, and Rankine
  • Amount Units: Moles, millimoles, and micromoles

Ideal Gas Law (PV = nRT):

  • P: Pressure of the gas
  • V: Volume of the gas
  • n: Number of moles of gas
  • R: Universal gas constant (8.314 J/(mol·K))
  • T: Temperature in Kelvin

Common Conversions:

  • 1 atm = 101.325 kPa = 14.696 PSI = 760 mmHg
  • 1 L = 0.001 m³ = 0.0353 ft³ = 0.2642 gal
  • 0°C = 273.15 K = 32°F = 491.67°R
  • 1 mol = 1000 mmol = 1,000,000 μmol

How to Use:

  1. Enter the known values for pressure, volume, temperature, or moles
  2. Select the appropriate units for each input
  3. Choose the unit you want to convert to
  4. View the converted result instantly
  5. Use the ideal gas law to solve for unknown variables

Applications:

This gas volume converter is essential for chemists, physicists, chemical engineers, students, and anyone working with gases. It's particularly useful for laboratory work, industrial processes, environmental monitoring, and educational purposes.
