# Distance Tool

I just measured a molecule. It is “19.2” long. 19.2 what? I guess nanometer?

I just did the math myself (quite difficult with many angles… I just guessed
because I know the C-C distance…) After a bit guesswork I get ~1.7nm = 17
Angstrom. So I bet Avo calculates in Angstrom.

I am pretty sure it is Angstroms - you are right that the units should be
displayed.

Units for distance are typically in Angstrom. But this raises a good
point for Carsten (or anyone else). What’s the best way to display
accented or special characters using Qt and QString.

For example, in HTML, that would be Å – or the “alpha” for the
unit cell angle is α Do we just need to look up the Unicode/
UTF-8 codes for these, or is there a conversion method? (This goes
for dealing with Designer as well.)

QString::fromUtf8(“°C”);

To be extrasure use

QString QString::fromUtf16 ( const ushort * unicode, int size = -1 ) [static]

That’s what I thought for code itself. Can you do this in designer?

Designer encodes this as UTF8 or UTF16 in the XML-file. You should
simply be able to write ° in Designer (or any other UTF8-char like æ
or ĸ.
