Gas Rating Chart Metric

Complete gas rating chart for metric meters showing the conversion from cubic meters (m³) measured over 2 minutes to kilowatts (kW) gross and net output.

Following is a complete gas rating chart for Metric meters. The assumptions are such that CV is 38.76MJ/m³, with a MJ to kW conversion of 3.6.

Converting from ft³/hr to m³/hr: ft³ ÷ 35.3 = m³/hr

Converting from m³/hr to ft³/hr: m³/hr × 35.3 = ft³/hr
