  2. Hardness comparison - Wikipedia

    en.wikipedia.org/wiki/Hardness_comparison

    ISO 18265: "Metallic materials — Conversion of hardness values" (2013) ASTM E140-12B(2019)e1: "Standard Hardness Conversion Tables for Metals Relationship Among Brinell Hardness, Vickers Hardness, Rockwell Hardness, Superficial Hardness, Knoop Hardness, Scleroscope Hardness, and Leeb Hardness" (2019)

  3. C string handling - Wikipedia

    en.wikipedia.org/wiki/C_string_handling

    Part of the C standard since C11, [17] in <uchar.h>, a type capable of holding 32 bits even if wchar_t is another size. If the macro __STDC_UTF_32__ is defined as 1, the type is used for UTF-32 on that system. This is always the case in C23. [15] C++ does not define such a macro, but the type is always used for UTF-32 in that language.

  4. 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 ...

  5. C data types - Wikipedia

    en.wikipedia.org/wiki/C_data_types

    UCHAR_MAX, USHRT_MAX, UINT_MAX, ULONG_MAX, ULLONG_MAX(C99) – maximum possible value of unsigned integer types: unsigned char, unsigned short, unsigned int, unsigned long, unsigned long long; CHAR_MIN – minimum possible value of char; CHAR_MAX – maximum possible value of char; MB_LEN_MAX – maximum number of bytes in a multibyte character

  6. AB magnitude - Wikipedia

    en.wikipedia.org/wiki/AB_magnitude

    Magnitudes in the AB system can be converted to other systems. However, because all magnitude systems involve integration of some assumed source spectrum over some assumed passband, such conversions are not necessarily trivial to calculate, and precise conversions depend on the actual bandpass of the observations in question.

  7. dBFS - Wikipedia

    en.wikipedia.org/wiki/DBFS

    The conversion level is chosen as the best compromise for the typical headroom and signal-to-noise levels of the equipment in question. Examples: [ 32 ] [ 33 ] [ 34 ] EBU R68 is used in most European countries, specifying +18 dBu at 0 dBFS.

  8. Scale factor (computer science) - Wikipedia

    en.wikipedia.org/wiki/Scale_factor_(computer...

    As long as this is taken into account, there is still no need to convert AZ and BZ into A and B before performing the operation; the result must be divided by Z before storing it back. After this, PZ will be stored as the result of the multiplication, which is indeed the scaled representation of the result of A * B (the desired answer) rather ...

  9. Scale ruler - Wikipedia

    en.wikipedia.org/wiki/Scale_ruler

    A scale ruler is a tool for measuring lengths and transferring measurements at a fixed ratio of length; two common examples are an architect's scale and engineer's scale.In scientific and engineering terminology, a device to measure linear distance and create proportional linear measurements is called a scale.
