How to Convert Milliarcseconds to Turns
The milliarcsecond and turn are both units of angle. 1 turn equals 1295998963.2 milliarcseconds. This means to convert milliarcseconds to turns, you divide by 1295998963.2.
Formula
Step-by-Step Example
Convert 5 mas to turns:
We need to convert milliarcseconds to turns
Since 1 turn = 1295998963.2 mas, divide by 1295998963.2
5 ÷ 1295998963.2 = 3.8580277778e-9
5 mas = 3.8580277778e-9 turn

About These Units
Milliarcsecond (mas)
A milliarcsecond (mas) is 1/1000 of an arcsecond. Milliarcseconds measure stellar parallax (nearest star: 768 mas), proper motion, and high-precision astrometry. The Gaia satellite measures positions to ~0.02 mas accuracy.
Turn (turn)
A turn (revolution, cycle, or rotation) is one complete 360° rotation. Turns simplify rotational calculations: 0.5 turns = 180°, 0.25 turns = 90°. Used in engineering, dance choreography, and describing rotational motion. Also called "full rotation" or "cycle."
