The calculator uses these formulas:
Where:
Details: Accurate conversion between GSM and pounds is essential for paper specification, purchasing, and ensuring compatibility with printing equipment.
Tips: Enter GSM value, select conversion type (text paper or basis weight), and optionally enter area for basis weight calculations.
Q1: What's the difference between text paper and basis weight?
A: Text paper conversion gives weight per 500 sheets (ream), while basis weight calculates total weight for a given area.
Q2: Why are there different conversion factors?
A: Different paper types have different standard sizes and sheet counts per pound, requiring specific conversion factors.
Q3: What is a typical GSM for office paper?
A: Standard copy paper is typically 80 GSM, which converts to about 54 lbs for text paper.
Q4: How accurate is this conversion?
A: The conversion is industry-standard for text paper, but always check with your paper supplier for exact specifications.
Q5: Can I convert lbs back to GSM?
A: Yes, for text paper: \( \text{GSM} = \text{lbs} \times 1.48 \).
