What is the differnce between Nm3/h and m3/h?

Nm³/h and m³/h both describe gas flow rates, but they use different reference conditions. Nm³/h refers to gas volume at 0°C and 1013 hPa, while m³/h (standard m³/h) uses 20°C and 1000 hPa. Because the temperature and pressure differ, the values are not...
