What millimeter size corresponds to an 8F sheath?

Explanation:
Size in millimeters is obtained by dividing the French size by 3, since 1F equals about 0.333 mm of outer diameter. For an 8F sheath, 8 ÷ 3 = 2.666... mm, typically written as 2.66 mm. The other numbers correspond to larger French sizes (e.g., 9F ~ 3.0 mm, 10F ~ 3.33 mm), but the 8F sheath is about 2.66 mm.
