    An output can be expressed with a fraction using |frac=N where N is the denominator. For example, |frac=8 rounds the output to the nearest eighth. {{convert|219|mm|in|abbr=on}} → 219 mm (8.6 in) {{convert|219|mm|in|abbr=on|frac=2}} → 219 mm (8 + 1 ⁄ 2 in) {{convert|219|mm|in|abbr=on|frac=4}} → 219 mm (8 + 1 ⁄ 2 in)

    en.wikipedia.org/wiki/French_catheter_scale

    The French scale measures and is proportional to the outer diameter of a catheter, with 1 French (Fr) defined as 1 ⁄ 3 millimeter, making the relationship: 1 mm = 3 Fr. Thus, the outer diameter of a catheter in millimeters can be calculated by dividing the French size by 3. [ 2 ]

    en.wikipedia.org/wiki/File:Mm_to_1_inch_fraction...

    English: a ruler from 0 to 1 inch (in.) in 1/32 inch divisions below the line and 1/2 millimetre (mm) divisions above the line to give a visual representation of the approximations. Principally designed to help visually determine if a metric or imperial drill bit will suffice.

  8. Inch - Wikipedia

    en.wikipedia.org/wiki/Inch

    Subdivisions of an inch are typically written using dyadic fractions with odd number numerators; for example, two and three-eighths of an inch would be written as ⁠2 + 3 / 8 ⁠ ″ and not as 2.375″ nor as ⁠2 + 6 / 16 ⁠ ″. However, for engineering purposes fractions are commonly given to three or four places of decimals and have been ...
