Vertical cross section with unit in meters

[マウロ]

Dear Grads-folks,

I have a doubt regarding how to build a vertical cross section with unit
in meters.

I checked the z levels, and I have a question. When I see the map in a
top view, I can see with degree units for both latitude and longitude.
When I check Z levels, I have the following results:

set z 1

LEV set to 0.02858 0.02858

LEV set to 15.4714 15.4714

ga> set z 27

Does it mean the values are in kilometers? Anyhow, I would like to make
a vertical cross section in meters or kilometers. If the values above
exposed are not in meters or kilometers, how can I convert into?

Thanks in advance,
Mauro
