The results differ by a few decimals:<br />1.2929838006781431,103.85254262698302 (yours)<br />vs<br />103.852542627029,1.29298990999197 (theirs)<br /><br />The coordinate I converted was 30139.47,30597.782 (location of City Hall Metro Station).<br /Daniel Lidströmhttps://www.blogger.com/profile/16935372605426490881noreply@blogger.com
