Claim
8 millimetres (3⁄8 in) in diameter
Correction
The unit conversion is incorrect: 3/8 inch is 9.525 mm, not 8 mm. Conversely, 8 mm is about 0.315 inch (roughly 5/16 inch).
Full reasoning
This sentence contains a straightforward metric–imperial conversion error.
NIST states that 1 inch is exactly 25.4 mm. Using that exact conversion:
- 3/8 inch = 0.375 × 25.4 = 9.525 mm
- 8 mm = 8 / 25.4 ≈ 0.315 inch
So 8 millimetres is not the same as 3/8 inch. A correct parenthetical conversion for 8 mm would be about 0.315 in (roughly 5/16 in), while a correct metric conversion for 3/8 in would be 9.525 mm.

The value for the inch, derived from the value of the Yard effective July 1, 1959, is exactly equivalent to 25.4 mm.
