How to convert seconds of arc to milliradians

1 ″ = 0.0048481368111 mrad, so multiply by 0.0048481368111 to go from seconds of arc to milliradians. Going the other way, 1 mrad = 206.264806247 ″.

mrad = ″ × 0.0048481368111
″ = mrad × 206.264806247

Worked example:

1 ″ = 0.0048481368111 mrad
5 × 0.0048481368111 = 0.0242406840555 mrad
