  2. Conversion of scales of temperature - Wikipedia

    en.wikipedia.org/wiki/Conversion_of_scales_of...

    This is a collection of temperature conversion formulas and comparisons among eight different temperature scales, several of which have long been obsolete.. Temperatures on scales that either do not share a numeric zero or are nonlinearly related cannot correctly be mathematically equated (related using the symbol =), and thus temperatures on different scales are more correctly described as ...

    It originates from British O scale. 1:40: 0.3 in: 7.620 mm The very early models of the British Coronation Coach and a few other horse-drawn wagons were made in this scale. Cheap soft plastic soldier figures are also made to this scale; there are a few kits to make vehicles for them. 1:38.4: 5/16" Scale for RC model ships, usually produced by ...

    (For example, a B in a regular class would be a 3.0, but in honors or AP class it would become a B+, or 3.33). Sometimes the 5-based weighing scale is used for AP courses and the 4.6-based scale for honors courses, but often a school will choose one system and apply it universally to all advanced courses.

  5. Academic grading in Vietnam - Wikipedia

    en.wikipedia.org/wiki/Academic_grading_in_Vietnam

    The Vietnamese grading system is an academic grading system utilized in Vietnam.It is based on a 0 to 10-point scale, similar to the US 1.0-4.0 scale.. Typically when an American educational institution requests a grade-point average calculated on the 4 point scale, the student will be expected to do a direct mathematical conversion, so 10 becomes 4.0, 7.5 becomes 3.0, etc.

  6. Scale of temperature - Wikipedia

    en.wikipedia.org/wiki/Scale_of_temperature

    This definition also precisely related the Celsius scale to the Kelvin scale, which defines the SI base unit of thermodynamic temperature with symbol K. Absolute zero, the lowest temperature possible, is defined as being exactly 0 K and −273.15 °C. Until 19 May 2019, the temperature of the triple point of water was defined as exactly 273.16 ...

  7. List of rail transport modelling scale standards - Wikipedia

    While HO scale is a 1:87 scale (3.5 mm to 1 foot), resulting in a 16.5 mm (0.65 in) gauge from real life prototype 1,435 mm (4 ft 8 + 1 ⁄ 2 in) standard gauge standard gauge. Conversely, modeling standard gauge in Lego trains would yield a scaling of (37.5:1435 =) 1:38.3.

    0: the heat of air in winter at which water begins to freeze. This point may be accurately determined by pressing the thermometer into melting snow. 0,1,2: the heats of air in winter 2,3,4: the heats of air in spring and autumn 4,5,6: the heat of air in summer 6: the heat at midday about the month of July 12: 1

    To calculate averages of suffixed grades, they are assigned fractional values, where 1 is 1.0, 1− is 1.3, 2+ is 1.7, 2 is 2.0, 2− is 2.3 and so on. As schools are governed by the states, not by the federal government, there are slight differences.
