This is a short example on how to change unit type for Yahoo Weather YQL query. This may be an overlooked bit of information but is covered quite well in the Yahoo! Weather Documentation. Mind you this is the RSS feed documentation but since YQL uses this feed as a backend service, you can pass the same parameters into it as you would if you were using the RSS feed directly. This is done using a feature called remote filters.

Here's what the documentation states:


That's great! So lets see how it behaves. I used the following query to test this (here's a YQL Console link to it):


Note that the units information is returned in Metric units.




When I change the 'u' parameter to 'f', units are returned in Imperial...


So there you go! Quite easy to do. Here's exactly what you get when you change the unit type:

Set to 'c':

• Distance - kilometres
• Speed - kilometres per hour
• Pressure - millibars
• Temperature - degrees Celsius

Set to 'f':

• Distance - miles
• Speed - miles per hour
• Pressure - pounds per square inch
• Temperature - degrees Fahrenheit
