hi.I just need some quick info on inches.

I am used to cm and not inches.

how much is

1 1.2'' in cm and 1 1.8'' in cm

thank you
Holt

2.2 cm = 1 inch.

nope, 2.54 cm per in

Here is a link the OP may find very valuable:

My Best,

Jonathan

ok thanks but what does 1 1.2'' mean?

I know that 1'' is 2.5cm but the 1.2''? and 1.8''?

thanks
Holt

My guess is that 1.2 means 1/2, and 1.8 means 1/8...

I assume that they mean 1 and a half inches, or 1 and 1 eight inch.

so with that i did my conversion and came up with this:

1 1.2 inches ( or 1.5 inches) = 3.81 cm

1 1.8 inches (or 1.125 inches) = 2.8575 cm

Hope I did that right, if not I'm sure someone else will chime in.

thanks.

can someone confirm that this is right?

that 1 1.2'' is 1.5''?

thanks
Holt

Pretty sure that is correct.

Confirmed as correct

who wrote 1.5" as 1 1.2"? that doesn't even make sense. is that derived from a specific industry or specific application or specific treatment? as an engineer, i have never seen that represented in that manner. 3/2" would make more sense to me but then again representing a measurement in that manner clouds the issue. there is too much ambiguity to represent a measurement in that manner....it can be misconstrued as 11.2 (eleven point two) inches or 1 1.2" (one and one point two) inches. now i'm confused and need to take some meds

All I gotta say is that this is the reason I never liked math!

Since every little line equals 1/16" I'm assuming that the ".2" is 2 of these lines, meaning 1/8". Maybe he's reading the ruler like it's in metric, where the .2 would be 2mm. Therefore .5" would equal 8/16 (1/2). It starts getting weird when you convert fractions of an inch to decimals.

they are doing it WRONG....there are standards here, rules to play by and a set of facts that everyone adheres to.........1 + 1 is 2, water is wet at room temperature, alden boots aren't the right colour, the belstaff indy is a rip off, and so on and so on.....you can't just adjust things to your liking and expect everyone to understand!!!......and the there was no grey hat in raiders {jumps under the plymouth}

uh oh...see....now i think i went too far.........

Indiana G (I am an engineer too btw) is right, that does not conform to any standard US method of writing inches in either decimal or fractional form. I hope this is not for something critical (like a Mars lander) or it could produce a costly error.
The substitution of a period for a slash (which would mean it was "one and one half inches" ) is all that makes any sense whatsoever.
Holt, please tell us, so that we might better figure this out, what does this refer to?

yeah holt....let us know so rambler and i can go over there and beat on the person with our slide-rules.........then we can sit and read 'dilbert' together and have a nice indygear mini-summit

Woah, settle down guys. The truth is, four out of every three Americans have difficulty with fractions.

{edit-- Sorry folks, I'm not intending to bait anyone here... I just saw that on a bumper sticker today and I thought it was incredibly appropriate for this thread.}

Hey, proof of point.....one of our main U. S. banks is call "Fifth 3rd" Bank.

Why they don't call it "1 and 2/3rd's" bank, I'll never know.

Hey, at least my slide-rule is 1936 period correct!
only kidding a little...I have some of my fathers and grandfathers drafting tools etc. The gadgets from the Indy era are quite cool and totally unlike their modern counterparts in quality.
I need to get a flatbed scanner so that I can pull some photos from my grandfathers college yearbooks to show the clothing styles. They are in the just pre WWI time-frame, i.e. Henry sr. and young Indy.
