You are correct that an uncertainty of 0.01 mm is the same as an uncertainty of 0.000 01 m.  The unedited version of your question contained a factor-of-ten error.

For numbers with many significant digits, or numbers which are for whatever reason written in cumbersome units, there are a couple of tricks people use to avoid getting confused and making factor-of-ten errors.  One is to write the digits in groups separated by spaces.  (And if you're fussy about such things and your software supports it, you can use non-breaking thin spaces).  Another is to write the uncertainty in the last digits of a measurement in parentheses next to the measurement — in your case, 
$$15.67(1)\text{ mm} \quad\text{or}\quad 0.015\,67(1)\text{ m}.$$  This format is common among precision measurement folks.

Significant error conversion
I'm experiencing a strange behaviour with Safari 7 on a webpage using web fonts

The use of the webfont is properly specified in the CSS with correct URL pointing to a .woff file hosted in the server that runs the site.

I clear the cache.

I load the home page, everything is fine.

I load a second page, the page doesn't load.

Inspecting the network activity it comes out that Safari has loaded every resource except the webfont;

it is aware the webfont is in cache, doesn't attemp to reload (no request is sent to the server) but is stuck processing that resource (the spinner keeps spinning).

Reloading the (second) page, results in getting the page loaded just fine.

Other browsers behave with no issues.

Is this a bug in Safari or I'm missing something? Is there any workaround?

Here is the CSS:

@font-face {
    font-family: 'myfont';
    src: url( '../font/my-font-webfont.eot' );
    src: url( '../font/my-font-webfont.eot?#iefix' ) format( 'embedded-opentype' ),
         url( '../font/my-font-webfont.woff' )       format( 'woff' ),
         url( '../font/my-font-webfont.ttf' )        format( 'truetype' ),
         url( '../font/my-font-webfont.svg#myfont' ) format( 'svg' );
    font-weight: normal;
    font-style: normal;
}
