Wilco™ CNG Capacity Calculator

This scf and energy capacity calculator uses pressure, temperature, total volume, and NIST data to calculate the compressed natural gas (CNG) volume in standard cubic feet (at standard pressure and temperature). The calculator can also express the volume in gasoline gallons (gge) or diesel gallon equivalent (dge). You can adjust the base gge or dge BTU values as needed to account for variations in liquid fuel formulation.
