It is in DDMM.MMMM format
You are 66 degrees North and 53 degrees West which is in the lower left hand corner of Greenland.
Take the minutes and decimal minutes and divide by 60; add to the degree value taking note of the hemisphere or sign.

I am trying to plot some data I have collected.
the data is collected in the Datum WGS84 zone 22 Northern hemisphere.
When I Try to transfer my points or grid to Googleearth I end up in Brazil instead of Greenland.
the data i am creating points from looks like this:
Northing Westing Depht
6658.7022,5342.2196,0.84
6658.7005,5342.2187,0.84
6658.6997,5342.2187,0.86
6658.6991,5342.2183,1.00
6658.6985,5342.2180,1.09
6658.6979,5342.2177,1.47
6658.6973,5342.2174,1.57
I am pretty sure that I used the right projection when i plottet the points and if you use the coordinates I imported into mapinfo on the greenlandic map-service site nunagis.gl i also end up the right place in Greenland
Also the coordinates look a little odd when they are imported into a mapinfo table. it seems like mapinfo adds a punctuation mark as a delimitation for thousands and Comma for the decimals i have added a picture of the imported data.
So it actually ends up with a punctuation mark in a place where i didn't put it and also changes the punctuation mark i added to a comma
hope somebody can help

Hi,
I'd check your projection first. While a UTM North 22 is appropriate for Greenland, your Northing coordinates are far too small. They should reflect a distance from the Equator and therefore be quite large numbers. Are you sure the projection is not something based on UTM-N22 but with a different false northing?

Well if it's lat/lon (WGS-84) I don't know where Zone 22 comes into play! Coordinates would normally be expressed in metres in a UTM-based system. If you can't find a tool to make points from this format, I'd suggest using mid$() and other string functions to extract the coordinates and update them into fresh lat/long fields which are of type float.
e.g.
update MyTable set lon = val(left$(MyNorthing, 3)) + val(mid$(MyNorthing, 4, 999)) / 60.0
and ditto for lat.
