Updated Coal Mine Methane Units Converter

Updated September 2023 

This tool converts methane (CH4) emissions to metric tons of carbon dioxide (CO2) equivalent (MTCO2e) and a variety of other measurement units and greenhouse gas (GHG) equivalencies.  These abstract equivalencies are also translated into relatable terms, such as annual emissions from cars or households. 

The latest update to this tool incorporates a global warming potential (GWP) value of 28 for methane. Learn more about GWPs and explore additional GHG equivalencies using EPA's Greenhouse Gas Equivalencies Calculator.

How to Use this Tool

More CMOP Tools

CMOP invites you to visit our Tools and Resources Library to explore resources by project phase and coal mine methane sources.

First, select the appropriate unit based on the value you wish to convert. Enter your value and press Tab or Enter to generate the answer(s).

Convert basic units:

  • Units Conversion

Convert methane (CH4) amounts to other units and express GHG equivalencies when:

  • Methane is measured in cubic meters (m3 CH4)
  • Methane is measured in cubic feet (ft3 CH4)
  • Methane is measured in pounds (lbs CH4)
  • Methane is measured in kilograms (kg CH4)
  • Methane is measured in metric tons (tonnes CH4)
  • Methane is measured in short tons (tons CH4)

Convert units of energy to other units and express GHG equivalencies when:

  • Energy is measured in British thermal units (Btu)
  • Energy is measured in megajoules (MJ) 

Calculations for conversions are approximate and should not be used for emission inventories or formal carbon emissions analysis.
