Imperial measurements
 
I've just measured something with my digital verniers to be: 0.0665" (could be 0.0700"), what is that in relation to 1/32", 1/16", 3/32", 1/8" etc?

And could someone explain the whole thing to me so I know in the future? :( I was born too late for all this old money stuff.

Cheers,

G

Just use one of these, I dont know why imperial still exists tbh. Its only good for your height because its easier to understand.

Use one of these mate

0.0665 works out at 0.17cm

Come on Graham, you can do fractions, 1/8th = 1 divided by 8 = 0.125

so rearranging 1/0.0665 = 1/15.03

or 1/0.07 = 1/14.3

If it was a 1/16th = 0.625"

should it not be in mm and not cm now? so 0.17cm should be 1.7mm?

Firstly cm's?????????????:o :o :o

come on lets work in mm's please! :D

If you want it in mm then its the fraction * 25.4 as 1inch = 25.4mm, so 1/16 = 1/16*25.4 = 1.587mm

Reet Greame, when using imperial measurements, you can use either a 'generic' measurement, like the 1/8th, 1/16th etc, and these are generaly used for regulat items like drill size, material thickness etc.... but when you are measuring and item for accuracy, then you use decimal places (thousanths of an inch).

1/8th - 0.125"

1/16th - 0.0625

So, as you can see, unless you are going down to like 128th's of an inch, accurate measurements are hard to do using 'fractions of an inch'.

p.s. It is even better when you are working on older Brittish aircraft which were built in imperial and repaird in metric, grrrrr
