Because of the identity property of multiplication, multiplying any quantity (physical or not) by the dimensionless 1 does not change that quantity. [5] Once this and the conversion factor for seconds per hour have been multiplied by the original fraction to cancel out the units mile and hour, 10 miles per hour converts to 4.4704 metres per second.
[1] The Charrière is measured by the ''outer'' diameter, and is defined as 1 Fr = 1/3 mm, and thus 1 mm = 3 Fr; therefore the diameter of a round catheter in millimetres can be determined by dividing the French size by 3. [2] The French units roughly correspond to the outer circumference of the catheter (see table below).
Metric ( SI) units. 25.4 mm. A fire hydrant marked as 3-inch. The inch (symbol: in or ″) is a unit of length in the British Imperial and the United States customary systems of measurement. It is equal to 1 36 yard or 1 12 of a foot. Derived from the Roman uncia ("twelfth"), the word inch is also sometimes used to translate ...
Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures. [1] " Nominal" refers to pipe in non-specific terms and identifies the diameter of the hole with a non-dimensional number (for example – 2-inch nominal steel pipe" consists of many varieties of steel pipe with the only criterion being a 2.375-inch (60.3 mm) outside ...
Very close to wargaming 20 mm figure scale (20 mm is actually 1:80.5). [10] 1:76.2: 4 mm: Model railways (00) UK model rail scale 4 mm scale (OO Scale, etc.). 1:76: 4.011 mm: Model railways (00) Military models. Military vehicles. Used with 4 mm to 1 foot models as well. 1:75: 4.064 mm Used by Heller for model ships. Also some Japanese aircraft ...
Conversions between units in the metric system are defined by their prefixes (for example, 1 kilogram = 1000 grams, 1 milligram = 0.001 grams) and are thus not listed in this article. Exceptions are made if the unit is commonly known by another name (for example, 1 micron = 10 −6 metre).
25.4 μm. A thousandth of an inch is a derived unit of length in a system of units using inches. Equal to 1000 of an inch, a thousandth is commonly called a thou / ˈθaʊ / (used for both singular and plural) or, particularly in North America, a mil (plural mils ). The words are shortened forms of the English and Latin words for "thousand ...
To convert inches to hands, the number in inches is divided by four, then the remainder is added after the radix point. Thus, a horse that measures 60 inches is 15 hands high (15 × 4 = 60) and a horse halfway between 15 and 16 hands is 15.2 hands, or 62 inches tall (15 × 4 + 2 = 62) [ 5 ] [ 7 ] Because the subdivision of a hand is a base 4 ...
