Hi SK,
To convert latitude and longitude to the UTM or UPS coordinate system, you can utilize the Mapping Toolbox in MATLAB.
Below is an example code that demonstrates this process:
% Create a map projection structure for a UPS/UTM projection
mstruct = defaultm("ups");
% Specify map limits and a reference ellipsoid for the map projection structure.
% Populate additional fields of the structure based on the map limits using the defaultm function again.
mstruct.maplonlimit = [-150 -30];
mstruct.geoid = referenceEllipsoid("grs80", "kilometers");
mstruct = defaultm(mstruct);
% Load coastline data and trim it to the specified map limits.
% Project the latitude and longitude coordinates using the projfwd function and the map projection structure.
load coastlines
[lat, lon] = maptriml(coastlat, coastlon, mstruct.maplatlimit, mstruct.maplonlimit);
[x, y] = projfwd(mstruct, lat, lon);
% Display the projected coordinates on a Cartesian plot.
figure
plot(x, y)
axis equal

Hope this helps!
