Doing unit conversions or general math is a known weak spot. I believe that 1,392,000 km is the correct diameter of the sun -- it just doesn't know how to convert those units.


No, it's exactly

2 * 695700 = 1391400

based on the most recent measurement from 2015:

https://en.wikipedia.org/wiki/Solar_radius

Any other value found on the web is based on some older estimate or some arbitrary approximation.


The radius of the sun is not exactly 695,700 km. The radius of the sun is approximately 695,700 km.

The nominal solar radius, which is and is intended to be an approximation, is defined to be exactly 695,700 km.
