Comparison of 1 square metre with some Imperial and metric units of area. The square metre (international spelling as used by the International Bureau of Weights and Measures) or square meter (American spelling) is the unit of area in the International System of Units (SI) with symbol m 2. [1] It is the area of a square with sides one metre in ...
A medium with a permeability of 1 darcy permits a flow of 1 cm 3 /s of a fluid with viscosity 1 cP (1 mPa·s) under a pressure gradient of 1 atm/cm acting across an area of 1 cm 2. Typical values of permeability range as high as 100,000 darcys for gravel, to less than 0.01 microdarcy for granite. Sand has a permeability of approximately 1 darcy ...
Metric units are units based on the metre, gram or second and decimal (power of ten) multiples or sub-multiples of these. According to Schadow and McDonald, [1] metric units, in general, are those units "defined 'in the spirit' of the metric system, that emerged in late 18th century France and was rapidly adopted by scientists and engineers ...
The unit, named after Blaise Pascal, is an SI coherent derived unit defined as one newton per square metre (N/m 2). [1] It is also equivalent to 10 barye (10 Ba) in the CGS system. Common multiple units of the pascal are the hectopascal (1 hPa = 100 Pa), which is equal to one millibar , and the kilopascal (1 kPa = 1000 Pa), which is equal to ...

A millimetre of mercury is a manometric unit of pressure, formerly defined as the extra pressure generated by a column of mercury one millimetre high, and currently defined as exactly 133.322 387 415 pascals [1] or approximately 133.322 pascals. [2] It is denoted mmHg[3] or mm Hg. [4][2]
Cubic hectometre. the volume of a cube of side length one hectometre (100 m) equal to a gigalitre. in civil engineering abbreviated MCM for million cubic metres. 1 hm 3 = 1 000 000 m3 = 1 GL. Cubic kilometre. the volume of a cube of side length one kilometre (1000 m) equal to a teralitre.
100 / 33 m. 3.030 m. 125,000 / 37,719 yd. 9 ft 11.3 in. Taiwanese fathom; Same as Japanese Jō. Taiwanese length units and the translation of length units in metric system (SI) shares the same character. The adjective Taiwanese (台) can be added to address the Taiwanese unis system. For example, 台尺 means Taiwanese foot and 公尺 ...
