An A4 page measures 21 cm by 29.7 cm.
21 by 29.8 cm
210mm & 297mm sides
The dimensions of A4 paper are 210 by 297 millimeters In cm, that's 21 cm × 29.7 cm Or about 9 by 12 inches.
The standard size of paper, known as A4, is based on the metric system and is used worldwide for consistency and compatibility. The dimensions of A4 paper (21.0 cm x 29.7 cm) optimize space efficiency while allowing for easy reading and handling.
A4 paper is 8 1/2 by 11 inches- standard size paper. Or, I believe, 21 by 30 cm in metric measurements.
i got 623.7 cm - it was hw (homework) :P ♥♥♥☻☻☺☺
210 x 297mm those how are looking for the answer in cm you can not do it in cm ***unless you be scientific you will be able to work it out ** it will something like 21 x 29.35 ADDED: It won't be "something like", though your mm to cm conversion is not quite correct. 210 x 297mm = 21.0 x 29.7cm, and that will give an answer in square centimetres, not linear cm. In any case the question was asking for the area specifically, just the "size". When you buy the paper, or set up a printer to handle it, you don't really need to know the numbers because the A4 designation is the international standard and most printer-drivers, duplicators, fax machines etc have "A4" in their menus.
A5 is 148mm by 210mm; it is almost precisely half the size of A4.
To calculate the GSM (grams per square meter) of a paper, you need to know the size of the paper in square meters. For an A4 sheet of paper (21 cm x 29.7 cm), the area is 0.06237 square meters (21 cm x 29.7 cm / 10,000). Dividing the weight (12 gms) by the area (0.06237 sq. m) gives a GSM of approximately 192.4.
Depends on its rating ( grams / square metre)So >A4 sheet = 0.21 * 0.297 = 0.06237 square metersSo >0.06237 * rating = weight>Typical office paper rating = 80 grams / square metreSo >0.06237 * 80 = 4.98969 grams
An A6 paper is 105 mm x 148 mm, which is approximately 4.13 inch x 5.83 inchThis is from Xerox's Helpful Facts about Paper, Table C-3: (Standard international cut-sheet sizes)The reference is available for download on Xerox.com website.
