Question Re: scale conversions

This is sort of the same thread - I've got a 1:250 scaled plan drawing and I need to know how to convert it to 1:200, or 1:100 so I can meaningfully read off the measurements
(I've got a basic scale ruler that only does 1:5 1:50 1:10 1:100 1:20 1:200 and 1:500 1:1000).
Help?!

Exclamation converting scale measurements 1:250 to 1:200

help! How do I convert the measurements on a plan from 1:250 (existing) to something I can read on my basic scale ruler? Thanks

A scale of 1:250 means 1 unit (any unit) on the drawing is 250 of the same unit in the real world, 1 cm on the drawing is 250 cm, or 2.5 m in the real world. So you could use a ruler and multiply by 250.

Alternatively, you can use 1:50 scale and multiply values read by 5, or you could use the 1:500 scale and divide the values read by 2 (you could use the 1:200 scale and multiply by 1.125, but that sounds pretty inconvenient)

If I am looking at a plan that is A3 size with a scale that is 1:100 for an A1 size plan, what calculation can I use to scale this?

I merged two posts. A scale of 1:n means that 1 unit on the drawing equals n units in the real world. So 1" on the drawing would be 5" or 50" or 100" (depending on scale) in the project.

However, if a drawing is copied and either expanded or reduces, the scale changes, so the drawing should ALWAYS have a scale with units marked off.
