Angle Calculator
Calculate (Angle Conversion)
Right Triangle Solver
What this tool does
A professional angle analysis companion that converts and analyzes angles across multiple units with precision and clarity.
Key capabilities
- Multi‑unit conversion: Degrees (°), Radians (rad), Grads (g) — instantly cross‑convert.
- Normalization: Map any angle to the standard range [0°, 360°) for consistent orientation.
- Trigonometric evaluation: Reliable sin, cos, tan based on normalized radians.
- Angle relations: Complement (90° − θ) and Supplement (180° − θ) with domain checks.
- Precision controls: Up to 6 decimal places; safely handles undefined tan at odd 90° multiples.
Conversion formulas
- rad = deg × π / 180
- deg = rad × 180 / π
- grad = deg / 0.9
- deg = grad × 0.9
Pro tips
- Normalization uses modulo 360 with wrap‑around for negatives.
- Periodicity: sin, cos, tan repeat every 2π; tan is undefined at (2k+1)×90°.
- Complement/Supplement are defined for 0° ≤ θ ≤ 180°; otherwise shown as N/A.
Where it shines
- Engineering drawings and CAD rotations
- Computer graphics and game development (object orientation, camera yaw/pitch/roll)
- Navigation and mapping (bearings, headings, compass readings)
- Circular statistics and signal processing (phase, polar transforms)
