A unit of measurement beginning with the letter R in mathematics is the Radian. This is a form of angular measurement where an angle of 1 Radian results in an arc length of a circle equal to the radius of the circle. Please see related links for a diagrammatic example.

1 Radian is exactly equal to 180/pi degrees or approx. 57.2 degrees.

Another unit which begins with the letter R is the Röntgen which was a unit of measurement for ionizing radiation. However it is no longer used in the SI system being replaced with charge per unit mass (C/kg).
