First you need to make sure that the Items are storing their values as Fahrenheit and inches using the “unit” attribute in the binding.
Number Weather_Temperature "Outside Temperature [%.0f] °F" <temperature> (gWeather_Chart) { weather="locationId=home, type=temperature, property=current, unit=fahrenheit" }
Number Weather_Pressure "Barometric Pressure [%.2f in]" <temperature> (gWeather) { weather="locationId=home, type=athmosphere, property=pressure, unit=inches" }
Depending on how you use it in your webview, also make sure to include or not include the units inside the “” part of the label. You will notice I do not include the “°F” for temp but I do include “in” for pressure.
Then I add them to my webview as follows:
<td rowspan="2"><img id="weather-icon" src="weather-data/images/${param:iconset}/${weather:condition.commonId}.png"/></td>
<td id="weather-temp">${item:Weather_Temperature.state}</td>
<td id="weather-temp-sign">°F</td>
<td>Pressure:</td>
<td>${item:Weather_Pressure}</td>
