Qibla in Koga and distance to Makkah
In Koga you pray towards the north-west, at an angle of 293.0° from true north; the Kaaba is 9,455 km away. We computed this angle with spherical trigonometry from the coordinates of Koga and those of the Kaaba (21.4225° N, 39.8262° E). Note that a compass points to magnetic north, which can differ by a few degrees from true north.
