Thanks Worth, so how do you know if the scale is inches to inches or
feet to feet, etc.? What is the default?
Scale is a ratio so it should be unit-less.
You can read it as one unit on the screen is equal to N units on the
ground. 1:2000 inches === 1:2000 ft

Scale is a ratio, for example: 1 inch = 24000 inches -or-
1/24000 -or- 1 ft. = 24000 feet____

*Subject:* [OpenLayers-Users] OpenLayers resolutions and scale
questions____
__ __
Hello all, I have a few questions that I can't seem to get cleared
up in the OpenLayers documentation. ____
* Someone asked me what is the units of measurement that are
displayed in the scale control? In other words 1:7M what? Or is
it unit-less since it's a ratio? Sorry if that's a dumb
question. ____
* Next, when you manually specify the resolutions of the map (i.e.
map.resolutions = [...,...,...];), what units are those? I
checked the map in the DOM inspector and it says the units are
'degrees', does that mean decimal degrees? ____
* Also if this or anything related to scale, resolution or
Geo-spatial accuracy in general is documented anywhere for
OpenLayers, can someone point me in that direction?____
Thanks in advance!____
