# Wind speed Mph or Km

Hi to all.
When i insert tag (round(#WND#)) \$#UNITSYS#=IMPERIAL?mph:mps\$ I have wind speed in mph.
Which tag have i to insert to have wind speed in Km?
Thx for any help
Cheers

you have to convert it manually like below and configure you settings in Metric.
\$#UNITSYS#=IMPERIAL?(round(#WND#)) mph:(round(3.6*#WND#)) km/h\$

I guess you mean km/h ?

Thx so much. Your help was precious it works perfectly

I think #WND# returns wind speed in selected units, I mean if you have Imperial you get the value in mph and if you have metrics you have the value in kph. You have to see what to show after the number in text like \$#WM#==F?mph:kph\$ I use #WM# now instead unitsys because is more reliable…

Hi
jeberuth suggested to me this expression \$#UNITSYS#=IMPERIAL?(round(#WND#)) mph:(round(3.6*#WND#)) km/h\$ and it seems to work great

I’m checking with the Facer team but if you use that expression the value in metrics will be wrong because it would be converted from the right value…

Hi
Sorry, but i’m a beginner and i need some more help. If i have understood well the correct formula is
this one?:
round(#WND#)) \$#WM#=IMPERIAL?mph:kph\$
Can you confirm? kph stands for Kilometers Per Hour?
If you can help i have another small problems with units. If i use #WCT# i obtain the temperature as a number, no C or F, but the number is in Farenight. Which tag must i use to have thet number in Celsius?
Cheers

Hi,
the initial formula is (round(#WND#)) \$#UNITSYS#=IMPERIAL?mph:mps\$
It gives you, in metric, the meter per second (quite standard format for wind).
I proposed to @mauriziosignorini1 a simple way to have it in km per hour (km/h) - the value seems to be correct except that it is rounded.

@carlosfilippa: please, let us know the feedback from facer. As I understand, #WND#, in metric gives the value in mps and not kph…

Confirmed, in metric is m/s so you have to convert to have k/h. Thanks!
