French s. (Fr) a s. for grading sizes of sounds, tubules, and catheters as based on a measurement of 1 / 3 mm and equaling 1 fr on the scale (e.g., 3 fr = 1 mm); grading to scale is carried out using a metal plate with holes ranging from 1 / 3 mm to 1 cm in diameter.Charrière s;

interval a temperature s. in centigrade or Fahrenheit units, a s. on which the intervals are equal but which has an arbitrary zero point; e.g., intelligence quotient values are values along an interval s.
