The formula to calculate the Thickness from GSM and Density is:
\[ \text{Thickness} (\mu m) = \left(\frac{\text{GSM}}{\text{Density}}\right) \times 1000 \]
Where:
GSM stands for grams per square meter and is a standard unit of measurement for the weight of paper and other materials. A higher GSM indicates a heavier and typically thicker material. It is an important specification for quality control in manufacturing and purchasing materials.
Let's assume the following values:
Using the formula:
\[ \text{Thickness} (\mu m) = \left(\frac{200}{0.5}\right) \times 1000 = 400000 \]
The thickness is 400,000 µm.
