scale drawing

[Jimbob87]

Got a scale drawing to read but no scale ruler. Its 1:20 would i be correct in thinking i can use a ordinary ruler and every 1cm would be the equivelant of 20cm?

 

Need abit of reasurance or guidance

As a related aside, quite often I get plans from some architects in peculiar scales.... easy way round it is measure at 1:100 [with a scale rule, or work on 1cm = 1m on a normal ruler] and multiply by 0.whatever the scale is shown as....

 

So... a plan at 1:75, which I don't have on my scale rule, would be measured at 1:100 and multiplied by 0.75, while a plan at 1:150 is measured at 1:100 and multiplied by 1.5 .... Also useful for measuring scale drawings of any scale with no scale rule at all...
