Angles convert between degrees and radians with π/180. Use it for trig, machining, and surveying.
How to use this calculator
- Set inputs: Enter the angle in the unit given.
- Pick units: Convert before calling trig libraries that expect radians.
- Verify: Normalize large angles if your app wraps.
Real-world examples
- Example: 45° = π/4 rad ≈ 0.7854 rad.
- Round-trip check: Convert the result back to the starting unit—if you do not land near your original value within rounding, confirm you picked the right direction (e.g., A→B vs B→A).

Use radians in calculus formulas; degrees in human-facing specs.
FAQ
Are angle unit converter results exact?
Fixed definitions (e.g., inches to cm) are exact. Values that depend on standards or rounding may differ slightly by display precision.
Why pick this hub instead of a single pair page?
Pair pages target one direction and one jump; this angle unit converter hub matches the multi-unit converter card where you can switch units freely.
How accurate is this conversion?
It uses the standard fixed conversion factor for these units. Results are exact to the precision shown, aside from normal floating-point rounding.
