  2. File size - Wikipedia

    en.wikipedia.org/wiki/File_size

    [2] Generally, a file system allocates space in blocks that are significantly larger than one byte. The file system allocates a number of blocks that together provide enough space to hold the file data. Unless the file fits exactly into the aggregated blocks, then some storage space allocated to the file is unused by the file.

  3. Photo print sizes - Wikipedia

    en.wikipedia.org/wiki/Photo_print_sizes

    The alternative Super series, denoted SnR, nR Plus or nR+, has an aspect ratio of 3∶2 (or as close as possible) and thus provides a better fit for standard 135 film (35 mm) at sizes of 8 inches or above. 5R is twice the size of a 2R print, 6R twice the size of a 4R print and S8R twice the size of 6R. 4D/6D is a newer size for most consumer ...

  4. Megabyte - Wikipedia

    en.wikipedia.org/wiki/Megabyte

    1 MB = 1 024 000 bytes (= 1000×1024 B) is the definition used to describe the formatted capacity of the 1.44 MB 3.5-inch HD floppy disk, which actually has a capacity of 1 474 560 bytes. [ 5 ] Randomly addressable semiconductor memory doubles in size for each address lane added to an integrated circuit package, which favors counts that are ...

  5. Kilobyte - Wikipedia

    en.wikipedia.org/wiki/Kilobyte

    In this convention, one thousand and twenty-four kilobytes (1024 KB) is equal to one megabyte (1 MB), where 1 MB is 1024 2 bytes. In December 1998, the IEC addressed such multiple usages and definitions by creating prefixes such as kibi, mebi, gibi, etc., to unambiguously denote powers of 1024. [ 10 ]

  6. CPK-MB test - Wikipedia

    en.wikipedia.org/wiki/CPK-MB_test

    The CPK-MB test (creatine phosphokinase-MB), also known as CK-MB test, is a cardiac marker [3] used to assist diagnoses of an acute myocardial infarction, myocardial ischemia, or myocarditis. It measures the blood level of CK-MB (creatine kinase myocardial band), the bound combination of two variants (isoenzymes CKM and CKB ) of the enzyme ...

  7. Kilogram-force per square centimetre - Wikipedia

    en.wikipedia.org/wiki/Kilogram-force_per_square...

    [1] [2] Use of the kilogram-force per square centimetre continues primarily due to older pressure measurement devices still in use. This use of the unit of pressure provides an intuitive understanding for how a body's mass , in contexts with roughly standard gravity , can apply force to a scale's surface area , i.e. kilogram-force per square ...

  8. Cubic centimetre - Wikipedia

    en.wikipedia.org/wiki/Cubic_centimetre

    A cubic centimetre (or cubic centimeter in US English) (SI unit symbol: cm 3; non-SI abbreviations: cc and ccm) is a commonly used unit of volume that corresponds to the volume of a cube that measures 1 cm × 1 cm × 1 cm. One cubic centimetre corresponds to a volume of one millilitre.
