System Information
Operating system: Windows-10-10.0.18362 64 Bits
Graphics card: GeForce GTX 1070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 441.66

Blender Version
Broken: version: 2.80 (sub 75), branch: master, commit date: 2019-07-29 14:47, hash: f6cb5f5449
Worked: (optional)

Short description of error
The attached blend file is set up in a way that 1 meter equals 1 pixel. However, when measuring the thickness of the hair (e.g. in Gimp) the hair is just 20 pixels thick, although the
"Radius Root" and "Radius Tip" properties are set to 20 meter. The cube however, has the expected edge length of 100 pixels. Therefore, the hair properties "Radius Root" and "Radius Tip" should actually be named "Diameter Root" and "Diameter Tip". Alternatively, I may have made a stupid mistake that I don't see.

Exact steps for others to reproduce the error
Open the attached blend file, have a look at the "Radius Root" and "Radius Tip" properties, as well as the size of the cube. Render the image and measure the dimensions of the hair and the cube.

Good News! This was (mostly) fixed Jan 6th and will be in the 2.82 release!

Mostly..."Radius Scale" wasn't corrected to the accurate label "Diameter Scale." I have set it to 1 in my example, along with the "Diameter Root." The plane that the single hair particle is on is the default 2m by 2m. In the pictures you can see that the root of the hair only covers 1m of the plane.

It should be "Root Diameter" and "Tip Diameter" in order to match the tool tip, and to make grammatical sense.

~~I will update this report to reflect this.~~

I will close this as resolved, Since your requested changes are in master. I'll open a new report to reflect the other needed changes.
