    The French scale, also known as the ... is a widely used measurement system for the size of catheters. ... 15.7 5.00 0.20 16 16.8 5.33 0.21 17 17.8 5.67

  3. Farad - Wikipedia

    en.wikipedia.org/wiki/Farad

    The farad (symbol: F) is the unit of electrical capacitance, the ability of a body to store an electrical charge, in the International System of Units (SI), equivalent to 1 coulomb per volt (C/V). [1]

  4. ESR meter - Wikipedia

    en.wikipedia.org/wiki/ESR_meter

    A professional ESR meter is more convenient for checking multiple capacitors rapidly. A standard measurement bridge, and many LCR and Q meters, can also measure ESR accurately, in addition to many other circuit parameters. The dedicated ESR meter is a relatively inexpensive special-purpose instrument of modest accuracy, used mainly to identify ...

  5. 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 ...

  6. Significant figures - Wikipedia

    en.wikipedia.org/wiki/Significant_figures

    If a length measurement gives 0.052 km, then 0.052 km = 52 m so 5 and 2 are only significant; the leading zeros appear or disappear, depending on which unit is used, so they are not necessary to indicate the measurement scale. 0.00034 has 2 significant figures (3 and 4) if the resolution is 0.00001.

  7. Hydrophobicity scales - Wikipedia

    en.wikipedia.org/wiki/Hydrophobicity_scales

    Hydrophobicity scales are values that define the relative hydrophobicity or hydrophilicity of amino acid residues. The more positive the value, the more hydrophobic are the amino acids located in that region of the protein. These scales are commonly used to predict the transmembrane alpha-helices of membrane proteins.

  8. Orders of magnitude (length) - Wikipedia

Scale model at megameters of the main Solar System bodies. To help compare different orders of magnitude, this section lists lengths starting at 10 8 meters (100 megameters or 100,000 kilometers or ...

  9. Japan Meteorological Agency seismic intensity scale

    en.wikipedia.org/wiki/Japan_Meteorological...

    The JMA scale is expressed in levels of seismic intensity from 0 to 7 in a manner similar to that of the Mercalli intensity scale, which is not commonly used in Japan.The JMA uses seismic intensity meters to automatically calculate peak ground acceleration in real-time, reporting intensities based on measurements from observation points.
