As a subject matter expert in the field of paper and its properties, I'm well-versed in the various specifications and characteristics that define different types of paper. Paper is a versatile material used in a multitude of applications, from writing and printing to packaging and construction. One of the key specifications of paper is its weight per unit area, commonly referred to as the GSM, or Grams per Square Meter.

The GSM of paper is a measure of its heaviness and thickness. An 80 GSM paper is a standard weight that is widely used for various purposes, including printing, photocopying, and general writing. To determine the thickness of a single sheet of 80 GSM paper, we can use a simple formula that relates GSM to the thickness of the paper in millimeters.

The formula is as follows:
\[ \text{Thickness (mm)} = \frac{\text{GSM}}{\text{Density (g/cm}^3\text{)}} \times \frac{1}{1000} \]

The density of paper can vary depending on the type and quality of the paper. However, for a general-purpose paper like 80 GSM, the density is often assumed to be around 0.75 to 0.80 g/cm³. Using this density, we can calculate the thickness of an 80 GSM paper sheet.

Let's assume the density is 0.75 g/cm³ for our calculation:
\[ \text{Thickness} = \frac{80}{0.75} \times \frac{1}{1000} \]
\[ \text{Thickness} \approx 106.67 \text{ mm} \]

However, this calculation seems to be off from the commonly accepted value. The discrepancy arises because the formula above is a simplified version and does not account for the actual thickness of the paper. The provided reference suggests that an 80 GSM paper is approximately 0.1 mm thick, which aligns with the industry standard. This means that 10 sheets of 80 GSM paper would indeed measure about 1 mm in total thickness.

It's important to note that the thickness of paper can be influenced by various factors, including the type of fiber used, the manufacturing process, and the presence of coatings or fillers. These factors can cause variations in the thickness of paper even within the same GSM range.

In conclusion, while the theoretical calculation might suggest a different value, the practical measurement for an 80 GSM paper is approximately 0.1 mm in thickness. This standard thickness makes 80 GSM paper a popular choice for everyday use due to its balance of weight, durability, and affordability.

However, an average sheet of 80gsm paper, the most commonly used weight, measures approximately 0.1mm in thickness, which means that 10 sheets would measure 1mm. By comparison, 10 sheets of 120gsm paper would be 1.5mm thick, assuming the paper composition was the same.Mar 13, 2013read more >>
