[postgis-users] Convert between SRID units and meters

[Peter Hsu]

I have a simple question.  I've loaded up shape files from the tigerline US census bureau.  Everything works fine, but I'm trying to find the area of a geometry in meters.  However, I'm only able to get the area in SRID units.

How can I convert from SRID units to meters?  Is this a linear conversion?  Or is it dependent on the latitude of the area in question? 

The SRID for the tigerline files is 4269
