An input unit can be converted to any number of output units—the outputs are specified as a "combination" by separating unit codes with a space (" ") or a plus (" + "). Using a space as a separator does not work if any of the unit codes contains a space. For example, each of the following converts 1.2 km 2 to acres, square yards, and hectares.
Traditional Japanese units of measurement or the shakkanhō (尺貫法) is the traditional system of measurement used by the people of the Japanese archipelago. It is largely based on the Chinese system, which spread to Japan and the rest of the Sinosphere in antiquity. It has remained mostly unaltered since the adoption of the measures of the ...
0.3048 m. 30.48 cm. 304.8 mm. The foot (standard symbol: ft) [1][2] is a unit of length in the British imperial and United States customary systems of measurement. The prime symbol, ′, is commonly used to represent the foot. [3] In both customary and imperial units, one foot comprises 12 inches, and one yard comprises three feet.
Double bed widths: 135, 140, 150, 180 cm (53, 55, 59, 71 in) In practice, bed sizes are usually categorized by the width. The length is typically 200 cm (79 in), but this may vary. The most common sizes are: [citation needed] 120 cm × 200 cm (47 in × 79 in) 150 cm × 200 cm (59 in × 79 in) 180 cm × 200 cm (71 in × 79 in)
Conversion of units is the conversion of the unit of measurement in which a quantity is expressed, typically through a multiplicative conversion factor that changes the unit without changing the quantity. This is also often loosely taken to include replacement of a quantity with a corresponding quantity that describes the same physical property ...
The last is typically longer than the foot heel to toe length by 4 ⁄ 3 cm (13.33 mm) to 5 ⁄ 3 cm (16.67 mm), or 2 to 2 + 1 ⁄ 2 Paris points, so to determine the shoe size based on actual foot length one must add 2 Paris points. Because a Paris point is 2 ⁄ 3 of a centimetre, a centimetre is 3 ⁄ 2 Paris points, and the formula is as ...
Height measurement using a stadiometer. Human height or stature is the distance from the bottom of the feet to the top of the head in a human body, standing erect.It is measured using a stadiometer, [1] in centimetres when using the metric system or SI system, [2] [3] or feet and inches when using United States customary units or the imperial system.
sievert (SI unit) Sv. ≡ 1 J/kg [44] = 1 Sv = 1 J/kg = 1 m 2 ⋅s 2. Although the definitions for sievert (Sv) and gray (Gy) would seem to indicate that they measure the same quantities, this is not the case. The effect of receiving a certain dose of radiation (given as Gy) is variable and depends on many factors, thus a new unit was needed to ...
