Development began in 1864 to replace the RBL 6-pounder 2.5-inch (64 mm) gun of 3 long hundredweight (340 lb; 150 kg), which had proved too heavy for a mountain gun. . Several Mks of 7-pounder RML of 2 long hundredweight (220 lb; 100 kg) were tried in 1865 by boring out and rifling old SBML bronze guns, but were still too
The introduction of Cordite also led to the decision that the 12-pounder was capable of firing a heavier shell up to 15 lb (6.8 kg). A 14-pound shell was adopted and the gun became a "15-pounder" from 1895. [4] At that point the 12-pounder 7 cwt became redundant.

However, the names of all SI mass units are based on gram, rather than on kilogram; thus 10 3 kg is a megagram (10 6 g), not a *kilokilogram. The tonne (t) is an SI-compatible unit of mass equal to a megagram (Mg), or 10 3 kg. The unit is in common use for masses above about 10 3 kg and is often used with SI prefixes.
The pound or pound-mass is a unit of mass used in both the British imperial and United States customary systems of measurement.Various definitions have been used; the most common today is the international avoirdupois pound, which is legally defined as exactly 0.453 592 37 kilograms, and which is divided into 16 avoirdupois ounces.

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. —
