converting scale measurements 1:250 to 1:200

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?!

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

how can i do a scale drawing to sho how furniture will fit into a room
the scale of the planis 1:20.The depth is 60cm thanks

1 unit on the plan is 20 units on the floor, that is what 1:20 means.

If the real dimension is 60 cm on the floor, then on the plan, it is 60/20 = 3 cm.

All dimensions on the "paper doll" plan furniture will be 1/20 the real dimensions

Hello, please could you tell me how to convert a 1:60 drawing to 1:50, 1:100 or 1:150?
thank you!!!

Best way: Redraw it to the new scale
Might work: Try to get the copier set to magnification ratios of exactly 83.333%, 166.666%, 250%

Normally the magnification isn't exactly right, but this may be an adequate approximation.

ticket-sales office that you are going to build should be on scale of 1:25, lenght of ticket office 5m what will be size on plan (mm)

5000 mm x 1/25 = 200 mm

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)

Thank you! So basic, so logical but I couldn't figure it out at all. My thanks
