How many kg does a ream of paper weigh?

Answer 1

Scrunched up or shredded paper, etc, is anyone's guess, so I'm answering with the case of printer paper piled up instead.

Start by measuring one ream of your paper. Mine here is A4 sheets, 2.5 kilogrammes, and is 5 centimetres thick. It contains 500 sheets of 80 gsm but that's not important.

The ISO system defines A0 as a square metre in area, so you need 2 of A1, 4 of A2, 8 of A3 or sixteen A4 reams to make a square metre in area and as these are each 5cm thick you'd need 20 reams high to produce the metre height. Therefore 16x20 = 320 reams of this paper would produce the cubic metre and would weigh around 800 kilogrammes.

Various different types of paper exist and you might find your paper produces different results, e.g. if you laser print it first, etc, I would say as a ballpark figure you could budget about 1 tonne per cubic metre and be fairly safe.

The other method is to understand that water weighs about 1000 kilogrammes per m3, take a sample of your paper, wrap it in clingfilm and see if it floats. If it sinks, the stuff weighs more than 1000, if it just about floats then it's not much less than 1000 and if it floats half in and half out, then it weighs around 500 kg/m3.

Answer 2

It depends on the grade of paper. In fact, paper is graded based on the weight of a ream (500 sheets) in the "basic sheet size" for that type of paper. Just to make it more complicated, "basic sheet size" is not necessarily the size in which the finished paper is sold (in fact, it's usually not).

Answer 3

"Cubic meter" is a unit of volume. "Kilometer" is a unit of length. They describe

different types of quantities, they have different physical dimensions, and they

can't convert to each other. If you could convert length into volume, then you'd

be able to calculate how many gallons tall you are.

Answer 4

Kilograms is a measure of weight, cubic meters is a measure of volume. To give any better answers, the substance of the cubic meter would need to be known.

Answer 5

It depends on density
