Fahrenheit is still used in the UK during a heatwave. 90F sounds more impressive than 32C. But when it gets cold 18F doesn't sound very cold as it's still a positive number. -8C sounds colder. So the UK press tend to mix and match according to the conditions.
Cheers,
Ray, Cheshire.

I was bored so I decided to add inHg, kPa, and mmHg to indexT.htm since I am now reporting in hPa. The following will work only if Cumulus is logging barometric pressure in hPa:

Code: Select all

  <tr>
    <td colspan="4" class="tableseparator_pressure">Pressure (MSL)</td>
  </tr>
  <tr class="td_pressure_data">
    <td>Barometer</td>
    <td><#press>&nbsp;<#pressunit></td>
    <td><#presstrend></td>
    <td><#presstrendval>&nbsp;<#pressunit>/hr</td>
  </tr>
  <tr class="td_pressure_data">
    <td>&nbsp;</td>
    <td><script>pressinHg = <#press> * 0.02953;document.write(pressinHg.toFixed(2));</script>&nbsp;inHg</td>
    <td>&nbsp;</td>
    <td><script>presstrendvalinHg = <#presstrendval> * 0.02953;document.write(presstrendvalinHg.toFixed(2));</script>&nbsp;inHg/hr</td>
  </tr>
  <tr class="td_pressure_data">
    <td>&nbsp;</td>
    <td><script>presskPa = <#press> * 0.1;document.write(presskPa.toFixed(2));</script>&nbsp;kPa</td>
    <td>&nbsp;</td>
    <td><script>presstrendvalkPa = <#presstrendval> * 0.1;document.write(presstrendvalkPa.toFixed(2));</script>&nbsp;kPa/hr</td>
  </tr>
  <tr class="td_pressure_data">
    <td>&nbsp;</td>
    <td><script>pressmmHg = <#press> * 0.75;document.write(pressmmHg.toFixed(1));</script>&nbsp;mmHg</td>
    <td>&nbsp;</td>
    <td><script>presstrendvalmmHg = <#presstrendval> * 0.75;document.write(presstrendvalmmHg.toFixed(1));</script>&nbsp;mmHg/hr</td>
  </tr>
