Angle conversions are useful for structural layout, roof pitch references, surveying bearings, machine setup, CNC work, trigonometry, radians in formulas, slope direction, mechanical rotation, optics, and navigation.
Use this converter when comparing degree-based, radian-based, survey, military, navigation, and precision angle units.
Your result shows the entered angle converted from the starting unit into the selected ending unit. The calculator also shows the conversion rate used so you can verify the calculation.
For engineering, construction, surveying, and geometry work, make sure the angle unit matches your drawing, calculator setting, formula, instrument reading, machine setup, or calculation sheet.
An angle measures the amount of rotation between two lines, rays, directions, or positions.
The SI-derived unit commonly used for plane angle is the radian, abbreviated as rad.
One degree equals approximately 0.0174533 radians.
One full turn equals 360 degrees.
Yes. This converter allows negative angle values because direction and rotation can be positive or negative.
