  2. Centimetre - Wikipedia

    en.wikipedia.org/wiki/Centimetre

    Different lengths as in respect to the electromagnetic spectrum, measured by the metre and its derived scales.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]

  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).

  4. Sheet resistance - Wikipedia

    en.wikipedia.org/wiki/Sheet_resistance

    The utility of sheet resistance as opposed to resistance or resistivity is that it is directly measured using a four-terminal sensing measurement (also known as a four-point probe measurement) or indirectly by using a non-contact eddy-current-based testing device. Sheet resistance is invariable under scaling of the film contact and therefore ...

  5. List of metric units - Wikipedia

    en.wikipedia.org/wiki/List_of_metric_units

    Metric units are units based on the metre, gram or second and decimal (power of ten) multiples or sub-multiples of these. According to Schadow and McDonald, [ 1 ] metric units, in general, are those units "defined 'in the spirit' of the metric system, that emerged in late 18th century France and was rapidly adopted by scientists and engineers.

  6. Metric system - Wikipedia

    en.wikipedia.org/wiki/Metric_system

    For the most part, the metric prefixes are used uniformly for SI base, derived and accepted units. A notable exception is that for a large measure of seconds, the non-SI units of minute, hour and day are customary instead. Units of duration longer than a day are problematic since both month and year have varying number of days.

  7. Unit of length - Wikipedia

    en.wikipedia.org/wiki/Unit_of_length

    Centimeters (cm) are avoided as they cause confusion when reading plans. For example, the length two and a half meters is usually recorded as 2500 mm or 2.5 m; it would be considered non-standard to record this length as 250 cm. [ 12 ] [ 13 ]

  8. Van der Pauw method - Wikipedia

    en.wikipedia.org/wiki/Van_der_Pauw_method

    The van der Pauw Method is a technique commonly used to measure the resistivity and the Hall coefficient of a sample. Its strength lies in its ability to accurately measure the properties of a sample of any arbitrary shape, as long as the sample is approximately two-dimensional (i.e. it is much thinner than it is wide), solid (no holes), and the electrodes are placed on its perimeter.
