An ahm (anglicised as "aum" - using the French spelling) was a Dutch and German measure of wine that was a fourth of a legger. It was also roughly equivalent to a British tierce [159.1 (≈159) liters, 35 Imp. gals.], a measure equal to a third of a butt. 1 half-pipe [55 Dutch gallons, 208.29 L iters, 45. 81 (≈46) Imp. gals.]
The hand is a non-SI unit of length equal to exactly 4 inches (101.6 mm). It is normally used to measure the height of horses in some English-speaking countries, including Australia, [4] Canada, Ireland, the United Kingdom, and the United States.
During the 1960s, some experimental races were run over a distance of 100 metres using hurdles with a height of 30 inches (76.2 cm). During the 1968 Summer Olympics , a decision was made to introduce the 100 m hurdles from 1969, using hurdles with a height of 33 inches (83.8 cm).
Anthropometric data such as height may be recorded in centimeters. [90] The body mass index (BMI) is expressed in kg/m 2, even though it may be computed from pounds and inches. Even if the medical practice takes height and weight data in terms of SI units, it is almost always discussed with the patient in terms of customary units.
The units of measurement of German-speaking countries consist of a variety of units, with varying local standard definitions. While many were made redundant with the introduction of the metric system, some of these units are still used in everyday speech and even in stores and on street markets as shorthand for similar amounts in the metric system.
Landings from the 30 foot (9.1 m) level up to the 150 foot (46 m) level are 3 feet 2 + 1 ⁄ 4 inches (0.97 m) by 25 feet 1 inch (7.65 m), while landings from the 160-foot (49 m) level to the 480-foot (150 m) level are 7 feet 10 + 3 ⁄ 4 inches (2.41 m) by 31 feet 5 + 1 ⁄ 2 inches (9.59 m). All stairs are on the north and south walls except ...
He determined the mathematical formula that related pendulum length to time (about 99.4 cm or 39.1 inches for the one second movement) and had the first pendulum-driven clock made. The first model clock was built in 1657 in the Hague , but it was in England that the idea was taken up. [ 54 ]
Radar is a system that uses radio waves to determine the distance (), direction (azimuth and elevation angles), and radial velocity of objects relative to the site. It is a radiodetermination method [1] used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, map weather formations, and terrain.
