If you fold an A3 paper in half you get 2 A4 papers.

The European sizing of paper starts with A0. Fold the two short sides together and you get A1. Fold the short two sides together again and you get A2, Do it again and you get A3, Do it again and you get A4, again and you get A5, again and you get A6, again and you get the uncommon tiny A7. I have never seen paper smaller than that sold commercially. If you measure a sheet of A4 [in centimetres] you can now work out all the sizes.

No, they could desire to not. there is dissimilar logic at the back of the metric paper sizes. not which you asked, yet A0 is a metre squared. this is the backside of a metre cubed. A metre cubed is the quantity of a ton of sparkling sea water at sea point, on the equator at 0 stages Celsius. A ton is one thousand pounds. a million kilo is 10x10x10cm. in case you have a litre of water, you have a kilo of water. It tells you the load, volume and the dimensions of containter you are going to be able to desire to place it in. Then, say as an occasion you wanted to furnish your water in its field to a chum, you would be waiting to wrap it ever so properly in some A sized paper. in case you wanted to wrap something else, you may artwork out the density as a ratio to clean water at 0 stages. consequently, you are able to artwork out the dimensions of your merchandise from the load of your merchandise (through kind in density via ratio) and you need to artwork out how lots paper you are going to be able to desire to wrap it. you would be conscious of what share sheets of A0/A1/A2/A3/A4 etc. paper to apply, because of the fact they stemmed from the metre. A0 is a metre squared in section. A0 = 841 × 1189mm = 1m^2 in case you fold A0 in a million/2 parallel to its shortest area, you get A1. Do it returned, and you get A2 etc. The ratio between the two facets is clever, because of the fact all the sizes in good condition completely regardless of paper length (A0, A1, A2 etc..) in case you wanted to explode a checklist from A4 to A3, it might in good condition completely because of the fact the ratio is precisely an identical. And the reason the numbers go larger as you go decrease, is using the fact the numbers are under no circumstances ending. I relies upon basically what share situations you want to halve the paper! I guess you weren't looking forward to that for an answer.
