The magnitude of such precision (152 decimal places) can be put into context by the fact that the circumference of the largest known object, the observable universe, can be calculated from its diameter (93 billion light-years) to a precision of less than one Planck length (at 1.6162 × 10 −35 meters, the shortest unit of length expected to be ...
If you multiply it by pi you get a bigger circumference, because the penis is not totally round, for example , my diameter is 5.7 cm and 5.7*pi= 17.898, my real circumference (measured with a measuring tape) is 17cm -/+ 0.2cm, so the most accurate way of measuring circumference is with a tape, I think. -betoelbicho
A US study published in 2015 of the stated preferences of a panel of 75 women using 3D-printed models as scale references showed a preferred penis length of 16 cm (6.3 in) and a preferred circumference of 12.2 cm (4.8 in) for long-term sexual partners, with slightly larger preferred sizes of a length of 16.3 cm (6.4 in) and circumference of 12. ...
European 7 mm cartridges all have 7.24 mm (0.285 in) grooves diameter. American 7 mm cartridges have 7.21 mm (0.284 in) grooves diameter. According to the official C.I.P. (Commission Internationale Permanente pour l'Epreuve des Armes à Feu Portatives) rulings the 7×57mm case can handle up to 390.00 MPa (56,565 psi) P max piezo pressure.
The M/88 bore originally had 7.90 mm (0.311 in) lands diameter and 8.10 mm (0.319 in) grooves diameter. The M/88 barrel bore specification was changed by 1894–1895 to 7.90 mm (0.311 in) lands diameter and 8.20 mm (0.323 in) grooves diameter to improve accuracy and reduce barrel wear in M/88 chambered arms.

[43] [44] [45] Since the 5.7×28mm cartridge also has a relatively small diameter, a relatively high number of cartridges can be contained in a magazine. [46] The cartridge has a loud report and produces considerable muzzle flash (when fired from a pistol), [47] but it has roughly 30 percent less recoil than the 9×19mm cartridge, improving ...
With a rimless, bottlenecked case using smokeless powder, the 7.65×25mm Borchardt adapted features of the 7.92 mm cartridge used in the 1888 pattern M/88 rifle, essentially scaling it down for use in a pistol.
