I'm calculating field of various features in my shapefile using QGis.

I'm getting some sample length as 0.134914579766986.

I want to know in what unit (eg: meters, km etc) is the above value ?

This is a measurement of whatever map units are specified in your project properties or CRS.

Check out:

http://hub.qgis.org/wiki/quantum-gis/Getting_Started_with_CRS_and_Projections

OR

Page 9 of http://wiki.osgeo.org/images/3/38/Db_foss_m1.pdf

"To set project properties click "[Settings > Project Properties]" in the main menu. The "Project Properties" window will appear. Click on the "[General]" tab and set Project Title and Map Units."
