    en.wikipedia.org/wiki/French_catheter_scale

    The Charrière is measured by the ''outer'' diameter, and is defined as 1 Fr = 1/3 mm, and thus 1 mm = 3 Fr; therefore the diameter of a round catheter in millimetres can be determined by dividing the French size by 3. [2] The French units roughly correspond to the outer circumference of the catheter (see table below).
