What is the angle converter?

The angle converter is a collection of calculators for changing one angle unit into another. Convert angle units for geometry, trigonometry, navigation, surveying, machining, and engineering.

Angle conversions are useful for geometry, trigonometry, navigation, surveying, machining, astronomy, and engineering drawings.

Available angle units

This category includes the following units:

Common angle use cases

Use this category when the same measurement appears in different unit systems, data sheets, calculators, reports, or regional conventions.

These short unit notes help readers choose the right starting unit before opening a specific conversion page.

Radian (rad)

A radian is the SI angle unit used in mathematics, trigonometry, physics, and engineering calculations.

Browse radians conversions

Degree (deg)

A degree is an angle unit equal to 1/360 of a full turn. It is widely used in geometry, navigation, surveying, and everyday angle measurement.

Browse degrees conversions

Gradian (grad)

A gradian is an angle unit where a right angle equals 100 gradians. It is used in some surveying and engineering contexts.

Arcminute (arcmin)

An arcminute is an angle unit equal to 1/60 of a degree. It is used in astronomy, navigation, optics, and precise angular measurements.

Browse arcminutes conversions

Arcsecond (arcsec)

An arcsecond is an angle unit equal to 1/60 of an arcminute. It is used for very small angles in astronomy, surveying, and optics.
