Flow — Nm³/h ↔ m³/min (at temperature)
Operating °C
Nm³/hm³/min (at T)
Pressure — mmAq ↔ Pa
mmAqPa
Concentration — g/Nm³ ↔ mg/Nm³
g/Nm³mg/Sm³
Velocity — m/s ↔ fpm (ft/min)
m/sfpm
A/C ratio — m/min ↔ cfm/ft²
m/mincfm/ft²
Power — kW ↔ HP
kWHP

ppm ↔ mg/m³ depends on molar mass and temperature (see the dewpoint calculator). Flow conversion ignores pressure variation.
