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.
A5 is 148mm by 210mm; it is almost precisely half the size of A4.
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
