What does this tool do?
The Angle Converter lets you enter an angle in degrees, radians, gradians, or turns and instantly converts it into six units at once: degrees, radians, gradians, turns, arcminutes, and arcseconds. It is a quick reference for students, engineers, and anyone working in CAD.
How to use it
- Enter your values into the fields.
- The result is calculated instantly.
- Read or copy the result.
Supported units
You pick the input unit from degrees, radians, gradians, or turns, and the results list updates instantly for all six units. For example, entering 90 degrees shows roughly 1.5707963 radians, 100 gradians, 0.25 turns, 5400 arcminutes, and 324000 arcseconds. Conversions use the standard constants: 180 degrees equals pi radians, 1 gradian equals 0.9 degrees, and 1 turn equals 360 degrees.
Usage tips
Click any result box to copy its value to your clipboard with a single tap, which saves time when pasting figures into a formula or code. Results are shown to up to 8 decimal places, giving enough precision for trigonometry homework and surveying calculations alike. Negative and decimal inputs are both supported, so you can convert values like -45 or 1.25 turns directly.
Frequently asked questions
Which units can I enter as input?
You can choose degrees, radians, gradians, or turns as the input. The output always shows all six units simultaneously.
What are arcminutes and arcseconds?
One degree splits into 60 arcminutes, and one arcminute into 60 arcseconds. They are used in astronomy and surveying to express small angles.
How precise are the results?
Values are displayed to up to 8 decimal places, which is enough for most engineering and mathematics uses.
