  2. French catheter scale - Wikipedia

    en.wikipedia.org/wiki/French_catheter_scale

    The French scale measures the outer diameter of the catheter, not the size of the internal drainage channel (inner diameter). For instance, a two-way catheter of 20 Fr and a three-way catheter of 20 Fr have the same outer diameter, but the three-way catheter has an additional channel for irrigation, reducing the size of its drainage channel.

    One US liquid pint: 5.46 × 10 −4: One sextarius: 5.51 × 10 −4: One US dry pint: 5.68 × 10 −4: One imperial pint 7.5 × 10 −4: The most common volume for wine and liquor bottles, also the size of an Australian long neck of beer; sometimes called a 'fifth' in the United States for its approximation to the once-common one-fifth-gallon ...

  4. ISO 216 - Wikipedia

    en.wikipedia.org/wiki/ISO_216

    Successive paper sizes in the series (A1, A2, A3, etc.) are defined by halving the area of the preceding paper size and rounding down, so that the long side of A(n + 1) is the same length as the short side of An. Hence, each next size is nearly exactly half the area of the prior size. So, an A1 page can fit two A2 pages inside the same area.

    The small rectangular chips with numbers are resistors, while the unmarked small rectangular chips are capacitors. The capacitors and resistors pictured are 0603 (1608 metric) package sizes, along with a very slightly larger 0805 (2012 metric) ferrite bead. Surface-mount capacitor A MOSFET, placed upon a British postage stamp for size comparison.

  6. Biblical and Talmudic units of measurement - Wikipedia

    The Books of Samuel portray the Temple as having a Phoenician architect, and in Phoenicia it was the Babylonian ell which was used to measure the size of parts of ships. [1] Thus scholars are uncertain whether the standard Biblical ell would have been 49.5 or 52.5 cm (19.49 or 20.67 in), but are fairly certain that it was one of these two ...

    en.wikipedia.org/wiki/Raindrop_size_distribution

    The raindrop size distribution (DSD), or granulometry of rain, is the distribution of the number of raindrops according to their diameter (D). Three processes account for the formation of drops: water vapor condensation, accumulation of small drops on large drops and collisions between sizes.
