16 sheets of A4 paper make exactly 1 sq m → 16 sheets/m^2 x 12 g /sheet = 192 gsm
A4 paper has an area of 1/16 sq m → 500 sheets at 80 gsm = 500 / 16 x 80 g = 2500 g = 2.5 kg
Area x gsm / 20000 =kg of bundle
Paper measurement If we're talking about weight, the worldwide standard is gsm (grams per square meter), and there are no practical differences in the measuring technique; nevertheless, we may measure paper thickness by GSM. A4 paper measures 210 mm by 297 mm.
70gsm means that 1 sheet of A0 (16 sheets of A4) should weigh 70 grams. Therefore assuming we are talking about 500 sheets of A4 paper then it will weigh (500/16)*70 grams or 2187.5 grams.
The unit 'gsm' stands for 'grams per square meter', which means that a 130 gsm paper is heavier than an 80 gsm paper. Whether the 130 gsm is thicker depends on the type of paper. However, 130 gsm of the same paper stock would obviously be thicker.
A4 is a standard paper size (1/16 square metres). The standard for printer paper is 80 gsm (grams per square metre). An 80 gsm sheet of A4 paper weighs 5 grams.
16 sheets of A4 paper make exactly 1 sq m → 16 sheets/m^2 x 12 g /sheet = 192 gsm
GSM in relation to paper - is the weight in Grammes of one Square Metre. For example - 'regular' A4 copier paper is usually 70 GSM. Craft paper such as origami paper (for folding into models) is usually much lighter at around 40 GSM, or sheets of card is normally 120 GSM
A4 paper has an area of 1/16 sq m → 500 sheets at 80 gsm = 500 / 16 x 80 g = 2500 g = 2.5 kg
One sheet of A4 paper (70 gsm) will weigh 0.042 Newtons.

Paper measurement If we're talking about weight, the worldwide standard is gsm (grams per square meter), and there are no practical differences in the measuring technique; nevertheless, we may measure paper thickness by GSM. A4 paper measures 210 mm by 297 mm.
A sheet of paper will typically have three dimensions. There is the length, the width and the thickness of the paper which is measured in GSM. Paper comes in many sizes but A4 is probably the most popular.
Some numbers that define paper are the size (A1, A2, A3, A4 etc) and the weight in grams per square metre. (gsm)
A4 paper size is 8.3in × 11.7in.
One tonne of paper is equal to 200, 000 sheets of A4 paper. (A number of sites report that it is equal to 40,000 sheets, but simple maths shows they are incorrect: Given...1 A4 page of 80gsm (gsm: Grams per Square Metre) 1m2 = 16 x A4 sheets So... 1 A4 sheets = 80g/16 = 5grams 1 tonne = 1,000,000grams Hence... 1 tonne = 1,000,000/5 A4 sheets = 200,000 A4 sheets)
