Since it shouldn't weigh over 20 lbs maximum, use the regular algorithm for recording pounds, lb's.
A larger block will weigh more, a smaller block will weigh less. Also, kilograms is a unit of mass, not of weight.
millimetres or centimetres.
Like any force, a weight should be measured in newtons. However, if you are looking for the equivalent of a "pound", that may also be the kilogram - which is a unit of mass, not of weight.
The mass of a fish tank should be measured in kilograms.
Weight is a force the unit of weight is Newton. F = ma Kilograms is the unit of Mass.
A larger block will weigh more, a smaller block will weigh less. Also, kilograms is a unit of mass, not of weight.
It weighs 32 kg. If you want to convert that to another unit of weight, you need to ask what it would be in that unit.

The dry weight of a medium density concrete block (215 x 450 x 100mm thick) is approximately 7.5Kg --- There are many different sizes, shapes and mixes used to make concrete block. Additionally the weight varies if the unit is wet or not since they absorb water. I see varying weights of 35 to 55 pounds for 8x8x16 block.
