U-1 had a displacement of 254 tonnes (250 long tons) when at the surface and 303 tonnes (298 long tons) while submerged. Officially, the standard tonnage was 250 long tons (254 t), however. [ 5 ] The U-boat had a total length of 40.90 m (134 ft 2 in), a pressure hull length of 27.80 m (91 ft 2 in), a beam of 4.08 m (13 ft 5 in), a height of 8. ...

For example, the CGS unit of force is the dyne, which is defined as 1 g⋅cm/s 2, so the SI unit of force, the newton (1 kg⋅m/s 2), is equal to 100 000 dynes. On the other hand, in measurements of electromagnetic phenomena (involving units of charge , electric and magnetic fields, voltage , and so on), converting between CGS and SI is less ...
A barn (symbol: b) is a metric unit of area equal to 10 −28 m 2 (100 fm 2).This is equivalent to a square that is 10 −14 m (10 fm) each side, or a circle of diameter approximately 1.128 × 10 −14 m (11.28 fm).
Astigmatism may be corrected with eyeglasses, contact lenses, or refractive surgery. [1] Glasses are the simplest and safest, although contact lenses can provide a wider field of vision . Refractive surgery can eliminate the need to wear corrective lenses altogether by permanently changing the shape of the eye but, like all elective surgery ...

Numbering was according to the sequence in which construction orders were allocated to the individual shipyards, rather than commissioning date; thus some boats carrying high numbers were commissioned well before boats with ...
A simple eye or ocellus (sometimes called a pigment pit [1] [2]) is a form of eye or an optical arrangement which has a single lens without the sort of elaborate retina that occurs in most vertebrates. These eyes are called "simple" to distinguish them from "compound eyes", which have multiple lenses. They are not necessarily simple in the ...
