:It's talking about how some squares like 18N SF don't have a 0,0, easting,northing as the southwest corner is outside of the zone. It's because of UTM. The squares are square in reference to the equator, and the vertical "central meridian" line in the centre of each zone.<ref>https://en.wikipedia.org/wiki/Universal_Transverse_Mercator_coordinate_system#Locating_a_position_using_UTM_coordinates</ref> In UTM, that line is 500,000 easting. 0 easting doesn't exist, it's in the zone to the west. So in MGRS/USNG, the squares on the edges of zones are clipped, but the squares on the west side still use the soutwest corner for 0,0 easting,northing, even though that's a possibly invalid point. I might try to clear up the article, but I want to do more work with USNG/MGRS first to ensure my understanding is correct.

== How coordinates of the joint of grid zone was made? ==

I don't know why some zone starting with zero numbers and some zone starting with the numbers 6 (starting point). [[Special:Contributions/27.109.113.245|27.109.113.245]] ([[User talk:27.109.113.245|talk]]) 08:55, 20 May 2023 (UTC)
