From the 10th grade onwards, including tertiary education, a 20-point grading scale is used, with 10 passing grades and 10 failing grades, with 20 being the highest grade possible and 9.5, rounded upwards to 10, the minimum grade for passing. This 20-point system is used both for test scores and grades.
The centimetre (SI symbol: cm) is a unit of length in the metric system equal to 10−2 metres ( 1 100 m = 0.01 m). To help compare different orders of magnitude, this section lists lengths between 10 −2 m and 10 −1 m (1 cm and 1 dm). 1 cm – 10 millimetres. 1 cm – 0.39 inches. 1 cm – edge of a square of area 1 cm 2.
The term Planck scale refers to quantities of space, time, energy and other units that are similar in magnitude to corresponding Planck units. This region may be characterized by particle energies of around 10 19 GeV or 10 9 J , time intervals of around 5 × 10 −44 s and lengths of around 10 −35 m (approximately the energy-equivalent of the ...

Imperial units. 3.937008 × 10 −9 in. Planck units. 6.187 × 1024 lP. The angstrom[1][2][3][4] (/ ˈæŋstrəm /; [3][5][6] ANG-strəm[5]) is a unit of length equal to 10−10 m; that is, one ten- billionth of a metre, a hundred-millionth of a centimetre, [7] 0.1 nanometre, or 100 picometres. The unit is named after the Swedish physicist ...
Its two equal sides are in the golden ratio to its base. [46] The triangle formed by two sides and a diagonal of a regular pentagon is called a golden gnomon. It is an obtuse isosceles triangle with apex angle 108° and base angle 36°. Its base is in the golden ratio to its two equal sides. [46]
Scale (map) A graphical or bar scale. A map would also usually give its scale numerically ("1:50,000", for instance, means that one cm on the map represents 50,000cm of real space, which is 500 meters) A bar scale with the nominal scale expressed as "1:600 000", meaning 1 cm on the map corresponds to 600,000 cm=6 km on the ground.
