Looks like you have decimal degrees for lat/long. You'll pobably need to convert to degrees, minutes and seconds. (60 seconds in a minute etc). Then you could convert from coordinates to Universal Transverse Mercator (UTM) grid coordinates, which are in metres. Thats the fun part. Read up on geodetic datum conversions. (Simple concept intro here: http://www.biodiversity.ea.gov.au/erin/tools/geo2amg.html ). There are various gov surveying web sites that explain the maths. Thats all I have time for now.
