Occasionally, the gun was fitted with a small shield to protect the gunners. Sd.Kfz. 250/11 leichter Schützenpanzerwagen (schwere Panzerbüchse 41 ...
A newton is defined as 1 kg⋅m/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. [2]

A Pak's weight is within the range of 229 kg (505 lb) to 10,160 kg (22,400 lb). The smallest caliber was 28 mm (1.1 in) and the largest was 128 mm (5.0 in). Over the six-year course of World War II the armor of the tanks steadily improved, so the size of the projectile had to increase.
Two types of high-explosive projectile were used with the K5. The 28cm G35 weighed 255 kilograms (562 lb) and contained a charge of 30.5 kilograms (67 lb) of TNT. The 28cm Gr.39 m. Hbgr. Z. was slightly heavier, weighing 265 kilograms (584 lb) and containing around 44.5 kilograms (98 lb) of TNT. These projectiles were pre-rifled with angled ...
The metre, kilogram, second system of units, also known more briefly as MKS units or the MKS system, [1] [2] [3] is a physical system of measurement based on the metre, kilogram, and second (MKS) as base units. Distances are described in terms of metres, mass in terms of kilograms and time in seconds.
