Let me share with you some figures on our Qiblat from Kuala Lumpur,Malaysia.This information I obtained from Ustaz Shukri who gives a lecture every week at my surau:
Latitude: 3º 05' 17" N,Longitude: 101º 46' 23" E
Latitude: 21º 11' 56" N,Longitude: 39º 49' 29.1" E
Distance between Kuala Lumpur and Kaabah: 6974km
1º deviation to Qiblat ( from Kuala Lumpur) is about 121.732km!
His advice to us:
Donot simply assume the direction of Qiblat.Even some mosques were found to be not set out properly.So,please verify our assumption. From Kuala Lumpur, Qiblat direction is 292º 31' 43.5".
