Definition

Noun: A standard quantity used to measure angles. It is a unit that defines the magnitude of a rotation or the difference in direction between two intersecting lines.

Usage

The term "angular unit" is used in mathematics, physics, engineering, and navigation to specify the size of an angle. Common angular units include degrees, radians, and gradians.

Examples

• A full circle contains 360 degrees, which is the most familiar angular unit.
• In calculus, the radian is the preferred angular unit because it simplifies many formulas.
• The surveyor set the instrument to measure the land plot's corners in the angular unit of gradians.

Advanced Usage

• "Steradian": While not a unit for plane angles, the steradian is the SI angular unit for measuring solid angles in three-dimensional space.
• "Arcminute" and "Arcsecond": These are smaller subdivisions of the degree, used for precise measurements in astronomy and geography.

Variants and Related Words

• Angle (n): The figure formed by two rays sharing a common endpoint, measured in angular units.
• Angular (adj): Relating to or having angles.
• Angular Measure (n): The system or process of measuring angles using angular units.

Synonyms

• Unit of angular measure
• Angle unit

Related Phrases

• Unit of measurement: A general term for any definite magnitude of a physical quantity.
• SI unit: The International System of Units, which defines the radian as the unit for plane angles.
