Ice meter... Objective methods of the icing measurements are based on the icing weight determination related to the unit of area(in meteorology) or to the unit of length(in power supply). The hard rime was determined with the aid of the so-called icing meter bars. They were represented by two wooden bars of 32 mm diameter and 1 m length, i. e. the surface area equals 0, 1 m² per 1 bar. Bars were placed horizontally and perpendicularly to each other. First of them was oriented in north-south direction, the second east-west. The amount of water was measured and result recalculated to kg. m-². These ice meter bars made possible quite reliable evaluation of the icing without having the continual measurement. Nevertheless they are not used contemporary in the meteorological service. 3, record 4, English, - ice%20meter

Record number: 6, Textual support number: 2 CONT
The speed of light in a vacuum is an important physical constant denoted by the letter c for "constant" or the Latin word "celeritas" meaning "swiftness". It is the speed of all electromagnetic radiations, including visible light, in a vacuum. More generally, it is the speed of anything having zero rest mass.... In metric units, the speed of light is exactly 299, 792, 458 metres per second(1, 079, 252, 848. 8 km/h). The fundamental SI unit of length, the metre, has been defined since October 21, 1983, as the distance light travels in a vacuum in 1/299, 792, 458 of a second; any increase in the precision of the measurement of the speed of light would refine the definition of the metre, but not alter the numerical value of c. The approximate value of 3x108 m/s is commonly used in rough estimates. In imperial units, the speed of light is about 670, 616, 629. 2 miles per hour or 983, 571, 056 feet per second, which is about 186, 282, 397 miles per second, or roughly one foot per nanosecond. The speed of light when it passes through a transparent or translucent material medium, like glass or air, is slower than its speed in a vacuum. The ratio of c to the observed phase velocity is called the refractive index of the medium. 5, record 6, English, - speed%20of%20light
