  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.

    A less precise definition is one pica equals 0.166 inches (4.2 mm), and one point 0.01383 inches (0.351 mm). [27] [33] It was also noticed that 83 picas is nearly equal to 35 cm, so the Type Founders Association also suggested using a 35 cm metal rod for measurements, but this was not accepted by every foundry. [27]

  4. 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 millimeters; 1 cm – 0.39 inches; 1 cm – edge of a square of area 1 cm 2

    Chart illustrating the increase in height of racehorses, from 14 hh (142 cm) in 1700 to 15. 2 + 1 ⁄ 2 hh (159 cm) in 1900. Today the hand is used to measure the height of horses, [2] ponies, and other equines. It is used in the US and also in some other nations that use the metric system, such as Australia, New Zealand, Canada, Ireland and ...

  6. Unit of length - Wikipedia

    en.wikipedia.org/wiki/Unit_of_length

    American surveyors use a decimal-based system of measurement devised by Edmund Gunter in 1620. The base unit is Gunter's chain of 66 feet (20 m) which is subdivided into 4 rods, each of 16.5 ft or 100 links of 0.66 feet. A link is abbreviated "lk", and links "lks", in old deeds and land surveys done for the government.

  7. Shoe size - Wikipedia

    en.wikipedia.org/wiki/Shoe_size

    A child's size zero is equivalent to 4 inches (a hand = 12 barleycorns = 10.16 cm), and the sizes go up to size 13 + 1 ⁄ 2 (measuring 25 + 1 ⁄ 2 barleycorns, or 8 + 1 ⁄ 2 inches (21.59 cm)). Thus, the calculation for a children's shoe size in the UK is: child shoe size (barleycorns) = 3 × last length (in) − 12. equivalent to:
