How to Convert Degree to Milliradian

1 degree = 17.4533 milliradians

Milliradian = Degree × 17.4533

Example: 15° × 17.4533 = 261.8 mrad

Reverse Conversion

To convert milliradians back to degrees:

  • Remember, 1 milliradian equals 0.0572958 degrees.
  • To convert 261.8 mrad to°, multiply 261.8 x 0.0572958, resulting in 15°.

15 ° is also equal to:

  • 0.2618 radian
  • 16.667 gradian
  • 0.041667 turn
About these units

Degree: The degree (°) is a non-SI unit of plane angle defined as 1/360 of a full rotation.It is accepted for use with the SI due to its long-standing practical importance in navigation, surveying, engineeri...

Milliradian: The milliradian (mrad) is one thousandth of a radian.It is widely used in ballistics, laser alignment, optical engineering, and instrumentation.
