Feels Like as implemented at version 3.6.10 (see [[#Feels_Like|Feels Like section below Current condition web tags]]) uses Celsius for temperature and '''km per hour''' for wind speed. Again, you will need to do the appropriate conversions from the quoted recent history tags if you use different units.
Feels Like was implemented as a recent history web tag at version 3.6.11 (see [[#Feels_Like|Feels Like section below Current condition web tags]]) for the gradual introduction of feels like elsewhere. For earlier MX versions, and if you are using Cumulus 1, you can calculate it:
 
The formulas below use Celsius for temperature and '''km per hour''' for wind speed. Again, you will need to do the appropriate conversions from the quoted recent history tags if you use different units.


Calculation from recent history tags is much more complicated because there are 3 different calculations: Feels Like reports exactly same as wind chill for temperatures '''below''' 10°C or 50°F so the WC here should equal <#RecentWindChill h=3>:
