180cm does not equal 6 ft. There are not 30 cm in a foot.
This tip goes out to Odge.

http://www.roygardiner.com/gears.htm The BMI calculator bit allows you to use whatever units you like and will give Metric and Imperial in the answer.

And when a woman's parking, a space about 8' wide looks narrower than a Renault Clio so help them in.

Yes; divided by 2.54 gives 70.86614, or five feet ten point eight seven inches.

err it's not 2.5, it's 2.54
which = 70.8 inches., which is 5'11''
i know you work in the public sector, but the devil is in the details

no, by convention.
Edit: just checked, and it is by definition, apparently. 
A certain company is going to need to update a few drawings..... |

I round down/up accordingly so 2.54 becomes 2.5. An example of rounding up is trying to turn 70.8 inches into 71 inches to prove that 70.8" = 5'11" when it actually doesn't. it's ever so slightly less. Looks like I'm not the only person who's approximating to make a point does it?

Its all about resolution Richard, and Design ers like to ignor it as well, untill you insist.
The UCI could lean about it as well when setting minimum weight regualtions in a psuedo-technical document.

no. wrong again.
The 'agreed standard' for rounding (as you would have learned at your parents great expense) is that anything with a 1-4 in the right hand digit is rounded down, a 5-9 is rounded up

ah, so I can round up to make someone the right height but can't round down to approximate the height? ok, thanks.
