The formula to convert GSM to LBS is:
\[ LBS = \frac{GSM \cdot 0.00220462 \cdot 1000}{1.48} \]
Where:
Let's say the paper weight is 120 GSM. The conversion to LBS would be calculated as follows:
\[ LBS = \frac{120 \cdot 0.00220462 \cdot 1000}{1.48} \approx 178.77 \]
So, the paper weight is approximately 178.77 pounds per 1000 square feet.
GSM stands for grams per square meter and is an international standard for measuring paper weight. LBS, on the other hand, stands for pounds per 1000 square feet and is commonly used in the United States. The conversion between GSM and LBS is important for the paper industry, printing companies, and consumers to compare paper types and weights across different measurement systems.
