Simple question I hope..
Can I have Sea Level pressure displayed in both mb and inch on my web page and how easy is it to implement
Somebody commented that mb is more common now and they would prefer to see it that way, rather than edit a years worth of data by changing my system settings I thought I may be able to display both
Ie Pressure 30.12in (997mb) or something like

If you are talking about the 'standard' html templates you would need to add some JavaScript to do the math for the additional unit.
This bit of code should give whatever the alternative unit is for your current pressure:
Code: Select all
<script type="text/javascript">
<!--
function showAltBaro(input) {
if(<#pressunit> == "in"){ // convert to hPa
output = (input * 33.86388).toFixed(1);
output += " hPa";
}else{ // convert to inHG
output = (input / 33.86388).toFixed(2);
output += " inHG";
}
document.write(output);
} // END function showAltBaro
-->
</script>
and your html would be something like:
Code: Select all
.....
Pressure <#press> <#pressunit> (<script>showAltBaro(<#press>);</script>)
.....
Ooops - just realised <#pressunit> option should be 'in' NOT 'inHG' - corrected

Thanks, i found a way to do it after much fiddling but will try yours to see the effect.
I'm learning as I go along, my next step is to get the gauge to show alternate units via a radio button
Thanks again

ATM you've 'lost' a table cell.
If you try my code (which I've corrected an error in
), then try this chunk of html:
Code: Select all
<tr class="td_pressure_data">
<td>Barometer </td>
<td><#press> <#pressunit><br /><script>showAltBaro(<#press>);</script></td>
<td><#presstrend></td>
<td><#presstrendval> inHG/hr<br /><script>showAltBaro(<#presstrendval>);</script>/hr</td>
</tr>

The loss of cell was deliberate ... well it happened by accident and I quite liked the result, but when i get home i'll have a play with the code
