Sir Francis Beaufort. The scale that carries Beaufort's name had a long and complex evolution from the previous work of others (including Daniel Defoe the century before). In the 18th century, naval officers made regular weather observations, but there was no standard scale and so they could be very subjective — one man's "stiff breeze" might be another's "soft breeze"—: Beaufort succeeded ...
The introduction of this new design did not however stop continued use and production of the 13.2×99mm Hotchkiss "Long" cartridge by countries whom had already adopted it and in 1939 the cartridge saw new interest on the export market due to the newly developed 13.2 mm FN Browning aircraft machine gun, which was offered in both 12.7 × 99 mm ...

The 13.2 × 92 mm SR, also known as Mauser 13.2 mm TuF (German: Tank und Flieger; literally "tank and aircraft", historical military designation), is a semi-rimmed rifle and machine gun cartridge developed by the German Empire for anti-tank and anti-aircraft use which was introduced during World War I.
From 1.0 through 2.95 mm, sizes are defined as follows, where N is an integer from 10 through 29: N · 0.1 mm; N · 0.1 + 0.05 mm; From 3.0 through 13.9 mm, sizes are defined as follows, where N is an integer from 30 through 139: N · 0.1 mm; From 14.0 through 25.0 mm, sizes are defined as follows, where M is an integer from 14 through 25: M ...
(E.g. 1 mm diameter wire is ~18 AWG, 2 mm diameter wire is ~12 AWG, and 4 mm diameter wire is ~6 AWG). This quadruples the cross-sectional area and conductance. A decrease of ten gauge numbers (E.g. from 12 AWG to 2 AWG) multiplies the area and weight by approximately 10, and reduces the electrical resistance (and increases the conductance ) by ...
The size of the lead shot that is produced is determined by the diameter of the orifice used to drip the lead, ranging from approximately 0.018 inches (0.46 mm) for #9 lead shot to about 0.025 inches (0.64 mm) for #6 or #7.0 shot, while also depending on the specific lead alloy that is used.
