is there an option for metric data in the client?

Owing to changes at a major online mapping provider, I have switched from using my dump1090 web page to the planefinder web page as my usual viewing option. My client is 4.1.1 armhf.
If I turn on "Range Rings" there is no scale. I think each ring is "50 miles" but it could be any distance, any value. I don't use imperial measures - they went out of use here in 1974. Is there an option for metric? I am used to seeing how many metres high a plane is, how many km away it is, and how many km/h it is travelling. I note that the air temp and barometer readings are metric.

Correct they are 50 miles and at the moment there are no settings to change that.

The values from the aircraft are as broadcast which is why you see ft, kts and a few others all mixed up.

We’ll look at adding metric conversions in the future.
The distances between the range rings in the 2D Plane Finder Client Map don't appear for me as 50 miles, but rather as spaced at 40 statute miles. Could somebody confirm? It is a somewhat unconventional choice, both in terms of units and ring spacings. Providing users with some options in this regard would be very welcome! Thanks, as always, for the great tools PF provides to the community.
