*hour angles (HA)*## Angles

This calculator is based on conversion of two angle units. An angle consists of two rays (as in sides of an angle sharing a common vertex or else called the endpoint.) Some belong to rotation measurements - spherical angles measured by arcs' lengths, pointing from the center, plus the radius. For a whole set of multiple units of angle on one page, try that Multiunit converter tool which has built in all angle unit-variations. Page with individual angle units.

# Converter type: angle units

First unit: second of arc ('') is used for measuring angle.

Second: hour angle (HA) is unit of angle.
