If you blow the (A4) map up to A3, the scale will be approx 1:200. (See JohnS's explanation for this in post#30).

Scale is exactly the same in inches and in metric. A scale of 1:50 means one unit on the drawing is 50 units on the project (real life). Doesn't matter whether units are inches or centimeters.

If dimensioning is feet and inches, drawing is more likely to use scales with 12 as a factor. 1:240 means 1" on drawing is 240" on project, but that is 20 ft, and it may be described as 1" = 20'. A metric drawing would be more likely to use 1:200 or 1:250. At 1:200, 1 cm on drawing is 200 cm on project, although that may be described as 1 cm = 2 m.

If you see a statement like that, convert to like units to determine scale.

What are the units? Are those dimensions on the plan or the project?
Anyway, 1 unit on the plan is 500 units on the project.

0.15 WHAT (meters, millimeters, inches, feet???)

If the scale is really 1:500, then 1 mm on the plan is 500 mm (0.5 m) on the project. However, if the drawing has been copied, it may have deliberately been shrunk or expanded to fit certain size paper, or the magnification may have just been off. Unless there is a scale bar on the drawing somewhere which you can measure, I wouldn't rely on the stated scale.

Guessing that the 0.15 is inches, that is 3.81 mm. If it represents 6m, scale is 1:1575 roughly. At 1:500, a 6m feature on the project should be 12 mm on the plan. The scale statement is based on like units, both metric, or both inch. If you mix, you will simply have a mess, and errors are pretty much guarenteed.
