PR: IFC Export Bug: Incorrect Values for 1905mm, 3810mm, 7620mm

### Problem Description

### Issue
The IFC Exporter from Revit incorrectly exports Length parameter values of 1905mm (75in), 3810mm (150in), and 7620mm (300in) to become:

#94=IFCPROPERTYSINGLEVALUE('BSS Length',$,IFCLENGTHMEASURE(0.020505249343832022),$);
#133=IFCPROPERTYSINGLEVALUE('BSS Length',$,IFCLENGTHMEASURE(0.082020997375328086),$);
#162=IFCPROPERTYSINGLEVALUE('BSS Length',$,IFCLENGTHMEASURE(0.041010498687664043),$);

### Revit Version

2024.3.x

### IFC for Revit Addon Version

24.3.2

### Windows Version

10 22H2

Reproduce the IFC export with Revit 2024.3.x and IFC for Revit 24.3.2 using Length values of 1905mm, 3810mm, and 7620mm, then inspect the generated IFC property values shown in the report. Done means those three values export as their correct lengths rather than the incorrect IFCLENGTHMEASURE values listed.
