I received a data set and the x and y data given is in decimal degrees and this is causing a huge error in a vorticity calculation I later use. I need the x and y data to be in metres and therefore I believe the best way to deal with this is to convert to UTM. Does anyone know how to do this?
The data set I have is X=255*302 structure & Y=255*302 structure. Would really appreciate some advice, haven't dealt with anything like this before.

Generally, it should look something like this.
radian = degree * pi/180; % Since your x (lng) and y (lat) are given in decimal degrees.
earth_radius = 6378.137;
lng = (x * radian - 135/180*pi) * earth_radius; %[km]
lat = atanh(sin(y)) * earth_radius; %[km]
Since you have a structures, it is better to write function mercator that your data can easily be implemented.
