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.
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

[25] [26] The standard FIFA football pitch for international matches is 105 m (344 ft) long by 68 m (223 ft) wide (7,140 m 2 or 0.714 ha or 1.76 acres); FIFA allows for a variance of up to 5 m (16.4 ft) in length in either direction and 7 m (23.0 ft) more or 4 m (13.1 ft) less in width (and larger departures if the pitch is not used for ...
Waist-to-height ratio: the average ratio for US college competitive swimmers is 0.424 (women) and 0.428 (men); the ratios for a (US) normally healthy man or woman is 0.46–0.53 and 0.45–0.49 respectively; the ratio ranges beyond 0.63 for morbidly obese individuals.
Originally in 1945, the divisions were based on the ring inside diameter in steps of 1 ⁄ 64 inch (0.40 mm). [6] However, in 1987 BSI updated the standard to the metric system so that one alphabetical size division equals 1.25 mm of circumferential length. For a baseline, ring size C has a circumference of 40 mm. [7]
The undecimogramme is a unit of mass equal to ten picograms (10 pg). The gamma (γ) is a unit of mass equal to one microgram (1 μg). The gravet is a unit of mass equal to one gram (1 g). The grave is a unit of mass equal to one kilogram (1 kg). The bar is a unit of mass equal to one megagram (1 Mg).
The International System of Units (SI), the modern form of the metric system, is preferred for many uses by the U.S. National Institute of Standards and Technology (NIST). [5] For newer types of measurement where there is no traditional customary unit, international units are used, sometimes mixed with customary units: for example, electrical ...
