The ancient Egyptian royal cubit (meh niswt) is the earliest attested standard measure.Cubit rods were used for the measurement of length.A number of these rods have survived: two are known from the tomb of Maya, the treasurer of the 18th dynasty pharaoh Tutankhamun, in Saqqara; another was found in the tomb of Kha in Thebes.
The scale. The Douglas sea scale, also called the "international sea and swell scale", was devised in 1921 [1] by Captain H. P. Douglas, who later became vice admiral Sir Percy Douglas and hydrographer of the Royal Navy. Its purpose is to estimate the roughness of the sea for navigation.
The physical group size equivalent to m minutes of arc can be calculated as follows: group size = tan( m / 60 ) × distance. In the example previously given, for 1 minute of arc, and substituting 3,600 inches for 100 yards, 3,600 tan( 1 / 60 ) ≈ 1.047 inches. In metric units 1 MOA at 100 metres ≈ 2.908 centimetres.
A tunnel 3,500 feet (1,100 m) in length undercuts the Bald Eagle vein 500 feet (150 m) below the surface outcrop and encounters the Sumdum Chief at a depth of 1,200 feet (370 m). From this working tunnel to the surface, most of the ledge material has been extracted by overhand stoping, and the slopes have been supported by square sets of timber.
Total length up to 11 m (36 ft). Petiole up to 6 m (20 ft) bearing a lamina up to 5 m (16 ft) long. [200] Up to 1.5 m (5 ft) in width. This is the tallest (up to 100 feet (30 meters)) of the five subspecies and the only single-trunked (up to two feet (61 centimeters) in diameter) form. Greatest surface area of any dicot leaf.
The tesla (symbol: T) is the unit of magnetic flux density (also called magnetic B-field strength) in the International System of Units (SI). One tesla is equal to one weber per square metre. The unit was announced during the General Conference on Weights and Measures in 1960 and is named [1] in honour of Serbian-American electrical and ...
The Flame Queen weighs 263.18 carats (52.636 g) and is somewhat triangular in shape, measuring 7.0 x 6.3 x 1.2 centimeters (2.75 x 2.50 x .50 inches). The Flame Queen was discovered in 1914 by three partners: Jack Philips, Walter Bradley and "Irish" Joe Hegarty, at the Bald Hill Workings, Lightning Ridge, New South Wales, Australia.
The typical tidal range in the open ocean is about 1 metre (3 feet) – mapped in blue and green at right. Mean ranges near coasts vary from near zero to 11.7 metres (38.4 feet), [ 4 ] with the range depending on the volume of water adjacent to the coast, and the geography of the basin the water sits in. Larger bodies of water have higher ...
