181
The (incorrect) metric conversion of the sexual position, the 69er, heard on a forgotten comedy show in the 90's and perpetuated by those who have repeated the joke and not checked a conversion calculator. 1 inch = 2.54 cm, answer should be 175.26.
Some credence should be given however for the homonym, "one ate one".
