#### Milliseconds conversion

A millisecond of arc is a unit of angular measurement that is equal to 10^{-3} of one second of arc. It is commonly used in fields that require unit for expressing very small angles, such as astronomy.

#### Right angle conversion

In geometry and trigonometry, a right angle is an angle that bisects the angle formed by two halves of a straight line. More precisely, if a ray is placed so that its endpoint is on a line and the adjacent angles are equal, then they are right angles.
