Supported Units

  • Radians (rad) - Standard SI unit for angle measurement. Commonly used in calculus and trigonometry, where 1 degree in radians equals approximately 0.0174533 rad (π/180)
  • Degrees (deg) - Most commonly used angle unit (360° = full circle). To convert degrees to radians, multiply by π/180
  • Gradians (grad) - Metric angle unit (400 grad = full circle)
  • Arcminutes (arcmin) - 1/60 of a degree
  • Arcseconds (arcsec) - 1/60 of an arcminute (1/3600 of a degree)

How to Calculate Angle in Radians

To calculate angles in radians from degrees, use the formula: radians = degrees × (π / 180). For example, 90 degrees equals π/2 radians (approximately 1.5708 rad). This online calculator handles all the math automatically, allowing you to convert any angle measurement instantly without manual calculations.
