A CPU cache is a hardware cache used by the central processing unit (CPU) of a computer to reduce the average cost (time or energy) to access data from the main memory. A cache is a smaller, faster memory, closer to a processor core, which stores copies of the data from frequently used main memory locations.
It takes approximately 31 empty aluminum cans to equal 1 pound. As of 2014, the average weight of an empty aluminum can is 14.9 grams.
How much does an average aluminium can weigh today? Today, aluminium cans are about 30% lighter than they were 25 years ago. Thinner, stronger sections are now being used with less metal, less energy and more savings in weight. An average aluminium can (without its contents, of course) weighed 16.55 grams in 1992. By 2001 the aluminium can weighed about 14.9 grams.
