    See Weight for detail of mass/weight distinction and conversion. Avoirdupois is a system of mass based on a pound of 16 ounces, while Troy weight is the system of mass where 12 troy ounces equals one troy pound.

  3. 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 ...

    But / = is not a constructible angle, since = is not the product of distinct Fermat primes as it contains 3 as a factor twice, and neither is /, since 7 is not a Fermat prime. [ 8 ] It results from the above characterisation that an angle of an integer number of degrees is constructible if and only if this number of degrees is a multiple of 3 .

    where is the k th-degree elementary symmetric polynomial in the n variables = ⁡, =, …,, and the number of terms in the denominator and the number of factors in the product in the numerator depend on the number of terms in the sum on the left. [16]

  6. Fahrenheit - Wikipedia

    en.wikipedia.org/wiki/Fahrenheit

    For an exact conversion between degrees Fahrenheit and Celsius, and kelvins of a specific temperature point, the following formulas can be applied. Here, f is the value in degrees Fahrenheit, c the value in degrees Celsius, and k the value in kelvins: f °F to c °C: c = ⁠ f − 32 / 1.8 ⁠ c °C to f °F: f = c × 1.8 + 32

  7. Scale of temperature - Wikipedia

    en.wikipedia.org/wiki/Scale_of_temperature

    The degree Celsius (°C) can refer to a specific temperature on the Celsius scale as well as a unit to indicate a temperature interval (a difference between two temperatures). From 1744 until 1954, 0 °C was defined as the freezing point of water and 100 °C was defined as the boiling point of water, both at a pressure of one standard atmosphere.

    For example, the freezing point of water is 0 °C and 32 °F, and a 5 °C change is the same as a 9 °F change. Thus, to convert from units of Fahrenheit to units of Celsius, one subtracts 32 °F (the offset from the point of reference), divides by 9 °F and multiplies by 5 °C (scales by the ratio of units), and adds 0 °C (the offset from the ...
