I chose Conduit Size - 1’’
The Conduit contains a single wire YEL_14_THHN
default.wdw:
default.ww1
Why is the value of "% full" 79%?
Must be 100%
Conduit Size (% full)
OK, this is from the Help file...
<HELP FILE START>
The .WDW file contains the wire information. You may have a different file for each project. Create a projname.wdw file and put in the same directory as your project file (.WDP). To use the same file for all projects, create or modify the DEFAULT.WDW file in the USER folder. In the Project Manager, right-click the project name and select Settings to find the full path.
There should be a separate line in the file for each AutoCAD Electrical wire layer. The line has three fields, each field separated by a semi-colon. The first field is the actual wire layer name used on the drawing. The second field is the wire layer description. This description is used in the AutoCAD Electrical Wire Colour/Gauge Label tool. The third field is the wire size.
For example, if you have a wire layer called 14_RED_THHN and you want the wire colour/gauge label to read #14AWG RED for this layer, and the wire itself has a wire diameter of 0.0087, the line in the .WDW file would read:
14_RED_THHN;#14AWGRED;0.0087
<HELP FILE END>
Going to a conversion site that gives a list AWG, Imperial and Metric wire sizes gives an imperial size of 0.0641 for #14AWG
https://technick.net/guides/electronics/awg_to_metric/
Therefore the lines in your WDW file for #14AWG wires should read
WHT_14_THHN;#14AWG WHT;0.0641
RED_14_THHN;#14AWG RED;0.0641
BLK_14_THHN;#14AWG BLK;0.0641
YEL_14_THHN;#14AWG YEL;0.0641
This should then give you a correct % Full reading for the conduit size.

Thanks, Brad!
I read Help file before asking a question.
But I did not understood by a formula calculated % Full.
I corrected the WDW - file according to your recommendations.
I added a line to the ww1 - file
Now the Conduit is filled to 5%. This is an incorrect value.
The original values for the WW1 file should be correct as they are dealing with conduit sizes and not wire sizes.
Try this spreadsheet which deals with this and actually gives some size values for schedule 40 PVC conduit.
Also, I don't believe that they make a 1/4' conduit. It would be to small to actually be useful.
The smallest I have seen is the 16mm or 11/2' and for me, the 16mm is actually very rarely used.
An electrician would normally use 20mm as the smallest unless there is a specific reason to use the 16mm.
Most wiring regulations call for a minimum percentage of the conduit to be free space.
1/4' conduit would have a usable are of around that of a pencil.
This would not be enough space for those regulations regarding free space in the conduit

I got the following:
File WDW
File WW1
Inner box size 1 inch: 0.34 (inches) х 25.4 х 0.8 = 6.9088 мм
The size of 15 wires YEL_14_THHN: 0.0641 х 15 = 0.9615
% Full: 0.9615 / 6.9088 х 100 = 13.9170
My result is consistent with the calculation program.
