  2. g-force - Wikipedia

    en.wikipedia.org/wiki/G-force

    One g is the force per unit mass due to gravity at the Earth's surface and is the standard gravity (symbol: g n), defined as 9.806 65 metres per second squared, [5] or equivalently 9.806 65 newtons of force per kilogram of mass.

  3. Grammage - Wikipedia

    en.wikipedia.org/wiki/Grammage

    Expressed in grams (g) per square metre (g/m 2), regardless of its thickness [1] (known as grammage). This is the measure used in most parts of the world. It is often notated as gsm on paper product labels and spec sheets. Expressed in terms of the mass per number of sheets of a specific paper size (known as basis weight).

  4. Specific strength - Wikipedia

    en.wikipedia.org/wiki/Specific_strength

    The SI unit for specific strength is Pa⋅m 3 /kg, or N⋅m/kg, which is dimensionally equivalent to m 2 /s 2, though the latter form is rarely used. Specific strength has the same units as specific energy , and is related to the maximum specific energy of rotation that an object can have without flying apart due to centrifugal force .

  5. FN 5.7×28mm - Wikipedia

    en.wikipedia.org/wiki/FN_5.7×28mm

    Bullets weighing 2.6 g (40 grains) or less are recommended for optimal use in 5.7×28mm applications, [47] but the 228.6 mm (1:9 in) rifling twist rate (distance the bullet must travel to complete one full revolution) used in the firearms' barrels will stabilize bullets weighing up to 4.5 g (70 grains).

  6. Gray (unit) - Wikipedia

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

    The measurement of absorbed dose is a complex problem due to scattering and absorption, and many specialist dosimeters are available for these measurements, and can cover applications in 1-D, 2-D and 3-D. [4] [5] [6]

  7. Baker percentage - Wikipedia

    en.wikipedia.org/wiki/Baker_percentage

    1 kilogram (kg) = 1,000 grams (g) = 2.20462262 lb 1 lb = 453.59237 g = 0.45359237 kg 1 oz = 28.3495231 g. In four different English-language countries of recipe and measuring-utensil markets, approximate cup volumes range from 236.59 to 284.1 milliliters (mL). Adaptation of volumetric recipes can be made with density approximations:

  8. Specific energy - Wikipedia

    en.wikipedia.org/wiki/Specific_energy

    Potential energy with respect to gravity, close to Earth, per unit mass: gh, where g is the acceleration due to gravity (standardized as ≈9.8 m/s 2) and h is the height above the reference level (giving J/kg when g is in m/s 2 and h is in m).

  9. Center of gravity of an aircraft - Wikipedia

    en.wikipedia.org/wiki/Center_of_gravity_of_an...

    A sample CG-moment envelope chart, showing that a loaded plane weighing 2,367 lb (1,074 kg) with a moment of 105,200 lb⋅in (11886 N⋅m) is within the "normal category" envelope. Center of gravity (CG) is calculated as follows: Determine weights and arms for all mass within the aircraft. Multiply weights by arms for all mass to calculate moments.
