How to Convert Latitude to Radians
- 1). Take the latitude measurements in degrees. (In our example, the two ends of the radian are on exactly the same longitude.)
- 2). Radians are measured by dividing the magical mathematical number Pi (3.14159 ...) by 180, which is the plane of a circle. This will give you roughly 0.01745327 radians.
- 3). Take the amount of radians and multiply it by the amount of degrees from your latitude. For example, a latitude that is 28 degrees will be equivalent to 28 * pi / 180 which equals 0.4886917 radians.
