trying to determine an IE browser setting that affects the behaviour of a weather widget

is anyone aware of a setting within MS Internet Explorer 11 that would cause the display of a weather widget (accuweather) to display "Farenheit" despite the generated code specifically stating "Celsius"?  here's a portion of the code:

   <div id="awcc1528741950009"
   <script type="text/javascript" src="">

as you can see, dataunit="c" and i've experimented with various data-language options ("en-us", "en-gb")...  the browser still displays it in Farenheit.

we've checked local PC regional settings, everything is set to English-Canada.
my users are in Canada so Celsius is the measurement unit we use.

out of 8 sites, 1 site does see "Celsius" on all their IE browsers, but we've been unable to determine why or find the setting that's different.

any ideas?

Hi David, thanks for this.  i am baffled that i cannot re-create this.  tried changing "f" to "c" in the code i originally posted to no avail.  what's odd is it works in Chrome.  and one of my sites says they do indeed see everything in Celsius (with IE).  7 of the 8 sites see Farenheit with the same code.  odd!

try using my <div id and data-uid and test

just tried that and it didn't change anything.  i did not change my data-locationkey.  here's my full code again with the changes you suggested:

<div style="width:90px">
<a href="" class="aw-widget-legal">
<div id="awcc1528929218083"
class="aw-widget-current" data-locationkey="53030" data-unit="c" data-language="en-us" data-useip="false" data-uid="awcc1528929218083">
<script type="text/javascript" src="">

just another reminder, this is only happening with IE browsers.  Chrome and Firefox are fine.
