The main difference between an 18mm, 20mm, and 22mm loupe is the size of the lens. The larger the lens diameter, the more light it can let in and the larger the field of view. A larger loupe may provide a clearer and broader magnified view compared to a smaller one.
The weight of 20mm metal for one cubic feet can vary depending on the specific type of metal being used. However, on average, the weight of 20mm metal is typically around 49.98 pounds per cubic feet.

There have been more than 2 dozen DIFFERENT 20mm cannon (search 20mm Wikipedia for examples). These used different shells, and had different barrel lengths, and so have different muzzle velocities. The 20mm used by the US and Allies during WW II had a muzzle velocity of ABOUT 2800 feet per second.
3kg / tonne of Rebar up to 20mm & 1.5kg / tonne above 20mm
The weight of a 20mm thick Hardox plate measuring 2320mm x 1570mm can be calculated using the formula: Weight = Length (m) x Width (m) x Thickness (m) x Density (kg/m^3). Assuming the density of Hardox material is around 7850 kg/m^3, the weight of this specific plate would be approximately 176.35 kg.
Different species of bees are different lenghts. An adult worker bee is 9mm - 18mm (0.35in - 0.71in) in length. Slightly larger, a typical queen bee is 18mm - 20mm in length (0.71 - 0.79) long.
The difference between the 10mm and 20mm lenses is the focal length they provide. The 10mm lens will give you higher magnification and a narrower field of view, while the 20mm lens will give you lower magnification and a wider field of view. Choose the lens based on your observing preferences and the object you want to view.
