  2. Pascal (unit) - Wikipedia

    en.wikipedia.org/wiki/Pascal_(unit)

    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 ...

  4. Kilogram-force per square centimetre - Wikipedia

    en.wikipedia.org/wiki/Kilogram-force_per_square...

    In SI units, the unit is converted to the SI derived unit pascal (Pa), which is defined as one newton per square metre (N/m 2). A newton is equal to 1 kgm/s 2, and a kilogram-force is 9.80665 N, [3] meaning that 1 kgf/cm 2 equals 98.0665 kilopascals (kPa).

  5. SI derived unit - Wikipedia

    en.wikipedia.org/wiki/SI_derived_unit

    The SI has special names for 22 of these coherent derived units (for example, hertz, the SI unit of measurement of frequency), but the rest merely reflect their derivation: for example, the square metre (m 2), the SI derived unit of area; and the kilogram per cubic metre (kg/m 3 or kgm −3), the SI derived unit of density.

    To avoid this, the kilopond was first defined at sea level and a latitude of 45 degrees, since 1902 via the standard gravity of 9.806 65 m/s 2. [ 2 ] Further disadvantages are inconsistencies in the definition of derived units such as horsepower (1 PS = 75 kp⋅m/s) and the missing link to electric, magnetic or thermodynamic units.

  7. Pressure - Wikipedia

    en.wikipedia.org/wiki/Pressure

    The SI unit for pressure is the pascal (Pa), equal to one newton per square metre (N/m 2, or kg·m1 ·s −2). This name for the unit was added in 1971; [7] before that, pressure in SI was expressed in newtons per square metre. Other units of pressure, such as pounds per square inch (lbf/in 2) and bar, are also in common use.

  8. Talk:Pascal (unit) - Wikipedia

    en.wikipedia.org/wiki/Talk:Pascal_(unit)

    It actually says "kg / (m·s^2)". I.e., the denominator is "metres times seconds squared", not "metres squared". N / m^2 is also correct, and makes immediate physical sense, but the newton is not an SI base unit. Hqb 18:36, 11 April 2010 (UTC) It all comes down to mass,distance and time units - the ones independent of other units.

  9. Newton (unit) - Wikipedia

    en.wikipedia.org/wiki/Newton_(unit)

    A newton is defined as 1 kgm/s 2 (it is a named derived unit defined in terms of the SI base units). [1]: 137 One newton is, therefore, the force needed to accelerate one kilogram of mass at the rate of one metre per second squared in the direction of the applied force.
