How do you convert an architectural scale measurement to an engineering scale measurement?

Answer 1

It's not too difficult once you see how its done. Let's take a look at some common arch. units converted to eng. units. when converting, remember, you do not have to convert the whole foot numbers. So youre just focused on converting the inches and fractions of an inch. So:

1" = 1"/12"= .08' (take your inches and divide them by 12")

2" = 2"/12" = .16'

3" = 3"/12" = .25'

and so on. for fractions of an inch:

1/8" = (1/8)/12 = .01' (divide 1 by 8, and then divide that 12)

1/4" = (1/4)/12 = .02'

1/2" = (1/2)/12 = .04'

and so on. For example, let's say you needed to convert 12' 5 1/2" to engineering units. It would be as follows:

12' is, well, 12'

5 1/2" can also be written as 5.5". So, 5.5"/12" = .4583

Therefore 12' 5 1/2" converts to 12.4583'.
