What is Qibla?
Qibla is the fixed direction towards the Ka’bah in the Grand Mosque in Makkah, Saudi Arabia. It’s the direction which all Muslims face when performing their prayers, wherever they are in the world.
How we calculate Qibla
We use the location of Kaaba (Lat 21.4224779 Long 39.8251832) and your current location (provided by GPS or manually) to determine the most direct route between two points on the globe, also known as the great-circle distance. This is calculated using the haversine formula. When viewed on a flat map, the line can sometimes appear bent due to the curvature of the earth.
Making sure the direction is accurate
Qibla Finder works with your device’s compass. To make sure that the direction is as accurate as possible, we recommend calibrating your compass before using.
