The Swedish 1-m Solar Telescope, with a lens diameter of 43 inches, is technically the largest, with 39 inches clear for the aperture.The second largest refracting telescope in the world is the Yerkes Observatory 40 inch (102 cm) refractor, used for astronomical and scientific observation for over a century.
The 6.5mm Creedmoor was designed for target shooting at longer ranges, and as such, couples a sensible ratio of case volume (3.40 ml) to bore area (34.66 mm 2 /0.3466 cm 2) with ample space for loading long slender projectiles providing good aerodynamic efficiency and external ballistic performance for the projectile diameter.

The Rhynland rood (Rijnlandse roede) was a standard Dutch measurement.It was changed in 1859 to the "Cape Foot" due to a drift in standards. 1 Rhynland foot (Rijnlandse voet) = 12 Rhynland inches (Rijnlandse duim) = 1.030 English feet.
3840 × 1600 (2.40:1 or 12:5); a number of computer monitors with this resolution have been produced, the first being the 37.5-inch (95 cm) LG 38UC99-W released in 2016. This resolution is equivalent to WQXGA (2560 × 1600) extended in width by 50%, or 3840 × 2160 reduced in height by ≈26%. [ 140 ]
"≈" means "is approximately equal to"; "=" means "is exactly equal to". One metre is exactly equivalent to 5 000 / 127 inches and to 1 250 / 1 143 yards. A simple mnemonic to assist with conversion is "three 3s": 1 metre is nearly equivalent to 3 feet 3 + 3 ⁄ 8 inches. This gives an overestimate of 0.125 mm.
The diameter of the equivalent large format round shape is rounded to the nearest 1 ⁄ 8 inch to provide the bar size. For example, #9 bar has a cross section of 1.00 square inch (6.5 cm 2), and therefore a diameter of 1.128 inches (28.7 mm). #10, #11, #14, and #18 sizes correspond to 1 1 ⁄ 8 inch, 1 1 ⁄ 4, 1 1 ⁄ 2, and 2-inch square ...
