  2. Centimetre–gram–second system of units - Wikipedia

    en.wikipedia.org/wiki/Centimetre–gram–second...

    1 unit of pressure = 1 unit of force / (1 unit of length) 2 = 1 unit of mass / (1 unit of length × (1 unit of time) 2) 1 Ba = 1 g/(cm⋅s 2) 1 Pa = 1 kg/(m⋅s 2). Expressing a CGS derived unit in terms of the SI base units, or vice versa, requires combining the scale factors that relate the two systems:

    Previous (1967): ⁠ 1 / 273.16 ⁠ of the thermodynamic temperature of the triple point of water. Current (2019): The kelvin is defined by setting the fixed numerical value of the Boltzmann constant k to 1.380 649 × 10 −23 J⋅K −1, (J = kg⋅m 2 ⋅s −2), given the definition of the kilogram, the metre, and the second. mole

  4. Standard cubic centimetres per minute - Wikipedia

    en.wikipedia.org/wiki/Standard_cubic_centimetres...

    Standard cubic centimeters per minute (SCCM) is a unit used to quantify the flow rate of a fluid. 1 SCCM is identical to 1 cm³ STP /min. Another expression of it would be Nml/min. These standard conditions vary according to different regulatory bodies.

    1.5 psi Pressure increase per meter of a water column [26] 10 kPa 1.5 psi Decrease in air pressure when going from Earth sea level to 1000 m elevation [citation needed] +13 kPa +1.9 psi High air pressure for human lung, measured for trumpet player making staccato high notes [48] < +16 kPa +2.3 psi

  6. Centimetre or millimetre of water - Wikipedia

    en.wikipedia.org/wiki/Centimetre_or_millimetre...

    A centimetre of water [1] is a unit of pressure. It may be defined as the pressure exerted by a column of water of 1 cm in height at 4 °C (temperature of maximum density) at the standard acceleration of gravity, so that 1 cmH 2 O (4°C) = 999.9720 kg/m 3 × 9.80665 m/s 2 × 1 cm = 98.063754138 Pa ≈ 98.0638 Pa, but conventionally a nominal maximum water density of 1000 kg/m 3 is used, giving ...

  7. Inch of water - Wikipedia

    en.wikipedia.org/wiki/Inch_of_water

    It is defined as the pressure exerted by a column of water of 1 inch in height at defined conditions. At a temperature of 4 °C (39.2 °F) pure water has its highest density (1000 kg/m 3 ). At that temperature and assuming the standard acceleration of gravity , 1 inAq is approximately 249.082 pascals (0.0361263 psi ).

    In the Zork series of games, the Great Underground Empire has its own system of measurements, the most frequently referenced of which is the bloit. Defined as the distance the king's favorite pet can run in one hour (spoofing a popular legend about the history of the foot), the length of the bloit varies dramatically, but the one canonical conversion to real-world units puts it at ...

  9. Actual cubic feet per minute - Wikipedia

    en.wikipedia.org/wiki/Actual_cubic_feet_per_minute

    Actual cubic feet per minute (ACFM) is a unit of volumetric flow. It is commonly used by manufacturers of blowers and compressors. [1] This is the actual gas delivery with reference to inlet conditions, whereas cubic foot per minute (CFM) is an unqualified term and should only be used in general and never accepted as a specific definition without explanation.
