Firmo,

I can't help but note that you are completely right with the format of specimen dimensions. A notation such as 20 mm x 6 mm x 14 mm is the correct one, no matter which unit you use, mm, cm or m.

Writing something as 20 x 62 x 14 mm, although everybody understands it, is improper and not mathematically rigorous since 20 and 62 are also mm each and so the unit symbol cannot be omitted. Another way to put it would be (20 x 62 x 14) mm with a 3 as superindex, but unfortunately I can't find the way for FMF to interpret the HTML code <sup></sup> while surprisingly it does understand the subindex, like mm3.

More details at http://physics.nist.gov/cuu/Units/checklist.html (go to item #12, Math notation).

Mindat.org photo galleries use the right notation too.

Hi Carles.

Thank you very much for your interesting post.
I didn´t know the link you give us, but item #12 is so clear.

I remember i read something about this theme precisely in your collection thread.

Also my math mind always tries to measure according to the coordinate axes X - Y - Z, width, height, depth.

These are two reasons that lead me to use that notation. I´m very glad that it is the correct format.

Best regards.

As an individual and (if permitted) as a site admin, I encourage all the FMF members to also use the right notation.
