ship distance in metric

[OE1MWW]

Hi,
Thanks for that fine software!
I am monitoring in central Europe, AIS-catcher does it flawless.
There is a plugin to convert ships dimensions to feet. Disabled it,
now I see demensions in meter, we are used to metric dimensions.

Unfortunately the distance calculation (I use Lat / Long) is still in 'nmi'
How can this be changed ?

greetings from Austria / Europe

my own solution - it works! ;-)

plugin named "distance_in_km.pjs"

// {"author":"OE1MWW","description":"displays unit of distance in km"}

getDistanceVal = c => Number(c * 1.852).toFixed(0);
getDistanceUnit = c => "km";

Yes, perfect! That is the way to do it.

Since the topic of units of measurement has come up, can I ask here too? How to change the bar scale at the bottom of the maps so that there are kilometres and nautical miles instead of statute ones.

Looks like in Leaflet you have to write a custom scale class for this.... Will have a look whether there is a simpler solution and then perhaps can be included in a plugin.
