GRP settings: Alha coeff thermal expansion hoop direction units

I set caesar units as:
Lenght=mm
Temp=°C
so Alha=[mm/mm°C].

In my project i have to use Alpha=18x10-6 [mm/mm°C].

when i insert this value inside Caesar
- configuration editor-->FRP properties-->frp_alpha
or inside
- special execution parameters-->FRP coef of thermal expansion

have i to insert the value "18" [so units are mm/mm°C) or have i to convert to in/in°F as shown in help (pressing F1 for help)?
In this case i have to insert "10" (=18/1.8) and not "18".


The question is:
Changing the "unit file" unit of measures, the choosen units will apply also to "alpha" or does it remain in/in°F?

thank you

CAESAR II will use your units. If temperature is °C, your alpha will be strain per °C and any temperatures (e.g., T1 or ambient) will be read as °C.
