  2. Reciprocal length - Wikipedia

    en.wikipedia.org/wiki/Reciprocal_length

    Spatial frequency is a reciprocal length, which can thus be used as a measure of energy, usually of a particle. For example, the reciprocal centimetre, cm1, is an energy unit equal to the energy of a photon with a wavelength of 1 cm. That energy amounts to approximately 1.24 × 10 −4 eV or 1.986 × 10 −23 J.

  3. Orders of magnitude (length) - Wikipedia

    en.wikipedia.org/wiki/Orders_of_magnitude_(length)

    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.

    en.wikipedia.org/wiki/Common_metre

    Common metre. Common metre or common measure[1] —abbreviated as C. M. or CM —is a poetic metre consisting of four lines that alternate between iambic tetrameter (four metrical feet per line) and iambic trimeter (three metrical feet per line), with each foot consisting of an unstressed syllable followed by a stressed syllable. The metre is ...

    For example, a wavenumber in inverse centimeters can be converted to a frequency expressed in the unit gigahertz by multiplying by 29.979 2458 cm/ns (the speed of light, in centimeters per nanosecond); [5] conversely, an electromagnetic wave at 29.9792458 GHz has a wavelength of 1 cm in free space.

    2.54 cm1 inch; 3.1 cm1 attoparsec (10 −18 parsecs) 3.5 cm — width of film commonly used in motion pictures and still photography; 4.3 cm — minimum diameter of a golf ball [32] 7.3-7.5 cm — diameter of a baseball [33] 8.6 cm × 5.4 cm — dimensions of a typical credit card [34]

  7. Centimetre - Wikipedia

    en.wikipedia.org/wiki/Centimetre

    The microwave is in-between 1 meter to 1 millimeter. A centimetre or centimeter (US/Philippine spelling), with SI symbol cm, is a unit of length in the International System of Units (SI) equal to one hundredth of a metre, centi being the SI prefix for a factor of ⁠ 1 100 ⁠. [1] Equivalently, there are 100 centimetres in 1 metre.
