  3. Kilogram - Wikipedia

    en.wikipedia.org/wiki/Kilogram

    The kilogram, symbol kg, is the SI unit of mass. It is defined by taking the fixed numerical value of the Planck constant h to be 6.626 070 15 × 10 −34 when expressed in the unit J⋅s, which is equal to kg⋅m 2 ⋅s −1, where the metre and the second are defined in terms of c and Δν Cs. —

  4. Pound (force) - Wikipedia

    en.wikipedia.org/wiki/Pound_(force)

    The pound-force is the product of one avoirdupois pound (exactly 0.45359237 kg) and the standard acceleration due to gravity, approximately 32.174049 ft/s 2 (9.80665 m/s 2). [ 5 ] [ 6 ] [ 7 ] The standard values of acceleration of the standard gravitational field ( g n ) and the international avoirdupois pound (lb) result in a pound-force equal ...

  5. Torque - Wikipedia

    en.wikipedia.org/wiki/Torque

    In the US, torque is most commonly referred to as the foot-pound (denoted as either lb-ft or ft-lb) and the inch-pound (denoted as in-lb). [ 17 ] [ 18 ] Practitioners depend on context and the hyphen in the abbreviation to know that these refer to torque and not to energy or moment of mass (as the symbolism ft-lb would properly imply).

    The weight has been reduced to 9.27 kg (20.4 lb), 2.23 kg (4.9 lb) lighter than the M/62. Its rate of fire of around 500–650 rounds per minute (RPM) [ 31 ] is significantly less than the Danish M/62's 1,200 RPM, but it allows for better control, greater accuracy, more conservation of ammunition, more versatile firing positions, and less risk ...
