CFM and Units, something is awry

[SDH]

Hi Garret,

Bumped into that problem as well
@T_Pover suggested this solution and it works great (and might also avoid other conversion problems…)

Space Imported Specified Return/Supply Airflow from excel, conversion?

You’ll probably get used to making the conversions in time, but if you don’t want to you can also use either of these 2 custom nodes from the ‘MEPover’ package: [image] The GetParameterAsValueString node will return the values as strings though, so for calculation you’ll need to convert to a numeric type first. The GetParameterAsValueString will return the values as you see them in you Revit Interface.
