1. What is GSM to Basis Weight Conversion?

The GSM (grams per square meter) to Basis Weight (pounds per ream) conversion is used in the paper industry to convert between metric and imperial measurements of paper density. This is particularly important for international paper trading and manufacturing.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• GSM — Grams per square meter (metric measurement)
• 1.48 — Conversion factor for text weight paper

Note: The conversion factor may vary slightly depending on paper type (text, cover, bond, etc.).

3. Importance of Paper Weight Conversion

Details: Accurate conversion between these units is essential for paper manufacturers, printers, and designers working with international specifications or comparing paper stocks from different regions.

4. Using the Calculator

Tips: Enter the GSM value in g/m². The calculator will automatically compute the equivalent basis weight in pounds (lbs).

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between GSM and basis weight?
A: GSM measures weight per square meter (metric), while basis weight measures weight per ream (imperial) of a specific sheet size.

Q2: Does this conversion work for all paper types?
A: The 1.48 factor is for text weight paper. Cover stock and bond paper may use slightly different conversion factors.

Q3: What is a typical GSM for office paper?
A: Standard office paper is typically 80-100 GSM, equivalent to about 20-30 lb text weight.

Q4: Why are there different basis weights for the same GSM?
A: Basis weight depends on the standard sheet size for that paper type, which varies between categories (text, cover, etc.).

Q5: How accurate is this conversion?
A: The conversion is generally accurate for most purposes, but for precise specifications, consult paper manufacturers' exact conversion charts.
