HVAC unit converter
The units that come up in every fan and duct calculation — volume flow, pressure, power, specific fan power, velocity, rotation speed, temperature, density, component dimensions and duct cross-section area. Type a value once, see it in every other unit instantly.
How to use it
Every card works the same way: type a value into the box, pick the unit you're starting from, and the list below updates instantly to show that same quantity in every other unit for that category. Change the unit dropdown and the input is reinterpreted in the new unit — nothing is lost.
Values you enter are remembered between visits, so this stays useful as a quick reference you come back to rather than something you re-type every time.
These are exactly the conversion factors we use internally across every CloudAir selection program, so a duty point you check here will match what the program itself reports. See how CloudAir handles units across a full catalogue →
