Event Forwarding speed difference

Hi,

so I enabled forwarding json event to my server via <entry key='forward.type'>json</entry> and proper url and so on.
This server is correlating events from Traccar and events from WicanPro (obd2 metrics).
I was expecting speed field to contain km/h however it strongly looks like miles/h.
First I thought most likely bug in my application, but it does nothing more then reads a speed field and saves it to InfluxDB.

Is it possible the speed coming from forwarding event is odd ? I see it's correct (km/h) from from Traccar UI interface.

or maybe it's another way, the tracking gps (watch proto) is sending in miles/h and this is simple kind of original data?

Why are you expecting "km/h"? We always use knots for speed.

@Anton

thanks for reminding me!
somewhat it stuck in my mind that I should expect km/h, because knots are for ships :P

GPS protocol uses knots.
