1- I converted projection 4326 to 32643(UTM zone 43N) to get are calculation. I used geometry operator as $area with creating a new field of decimal (real) type with width 10 and 2 precision. I tried with different widths and precisions, every time there are 7-8 digits after decimal, like, 2361773.81506348 2895003.41503906 1384160.6237793 10020411.4874268
2 Further I read in new functionality list of QGIS1.8 that area/length etc. may be calculated by using project (if in metric units) CRS in QGIS 1.8, without changing original CRS of layer if it is in Geographic coordinates. Is this feature available in 1.8?
