FIBA uses a marginally larger radius of 1.25 m (4 ft 1.2 in). Starting with the 2023–24 season, NCAA women's basketball reduced the size of the no-charge arc to a radius of 9 inches (22.86 cm)—in other words, the size of the basket. The no charge zone arc rule first appeared at any level of basketball in the NBA in the 1997–98 season. [8]
These bases are marked by canvas or rubber cushions, 18 inches (46 cm) [3] square and 3–5 inches (7.6–12.7 cm) thick. Adjacent to each of the two parallel 8.5-inch sides is a batter's box. All the bases, including home plate, lie entirely within fair territory. Thus, any batted ball that touches those bases must necessarily be ruled a fair ...

The three versions are four-wall, three-wall ...
NASA compares the required accuracy by analogy: "If the Webb primary mirror were the size of the United States, each [mirror] segment would be the size of Texas, and the team would need to line the height of those Texas-sized segments up with each other to an accuracy of about 1.5 inches".

With respect to the size of the boundaries, no boundary shall be longer than 90 yards (82 metres), and no boundary should be shorter than 65 yards (59 metres) from the centre of the pitch to be used. The equivalent ICC playing conditions (Law 19.1.3) for international women's cricket require the boundary to be between 60 and 70 yards (54.86 and ...
Seismic moment is measured in Newton-meters (Nm or N·m) in the SI system of measurement, or dyne-centimeters (dyn-cm; 1 dyn-cm = 10 −7 Nm) in the older CGS system. In the simplest case the moment can be calculated knowing only the amount of slip, the area of the surface ruptured or slipped, and a factor for the resistance or friction ...

In the game of cricket, the cricket pitch consists of the central strip of the cricket field between the wickets. It is 22 yd (20.12 m) long (1 chain) and 10 ft (3.05 m) wide. [ 1] The surface is flat and is normally covered with extremely short grass, but can be completely dry or dusty soil with barely any grass or, in some circumstances (that ...
