1. What is GSM to Lbs Conversion?

GSM (grams per square meter) and lbs (pounds per ream) are two common units for measuring paper weight. This conversion helps compare paper weights between metric and imperial systems.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• 1.48 — Conversion factor (g/m² to lbs per ream)
• 1 ream = 500 sheets of 17"×22" paper (standard basis size)

Example: 120 GSM paper converts to approximately 81 lbs (120 ÷ 1.48).

3. Importance of Paper Weight Conversion

Details: Understanding both GSM and lbs measurements is essential for printers, designers, and paper buyers working with international suppliers or specifications.

4. Using the Calculator

Tips: Enter the GSM value (grams per square meter) to get the equivalent weight in pounds (lbs). Common office paper is 75-90 GSM (50-60 lbs).

5. Frequently Asked Questions (FAQ)

Q1: Why are there two different measurement systems?
A: GSM is metric standard used worldwide, while lbs is traditional US system based on weight of 500 sheets.

Q2: Does paper size affect the conversion?
A: The conversion assumes standard basis size (17"×22"). Different sizes would require adjusted calculations.

Q3: What's the typical GSM for copy paper?
A: Standard copy paper is usually 80 GSM (about 54 lbs).

Q4: How accurate is this conversion?
A: The 1.48 factor provides good approximation for most paper types, though exact density may vary slightly.

Q5: Can I convert lbs back to GSM?
A: Yes, multiply lbs by 1.48 to get GSM (GSM = lbs × 1.48).
