GSM to Inches Formula:
| From: | To: |
The GSM to Inches conversion calculates the thickness of a material in inches based on its grammage (GSM - grams per square meter) and density. This is particularly useful in paper, fabric, and material science industries where thickness measurement is crucial.
The calculator uses the conversion formula:
Where:
Explanation: The formula converts the area density (GSM) to linear thickness by accounting for the material's density and converting from metric to imperial units.
Details: Accurate thickness calculation is essential for quality control, material selection, packaging design, and ensuring products meet specific dimensional requirements in various manufacturing processes.
Tips: Enter GSM value in g/m² and material density in g/cm³. Both values must be positive numbers. Common material densities: paper ≈ 0.8-1.2 g/cm³, cardboard ≈ 0.6-0.8 g/cm³.
Q1: Why is density important in this conversion?
A: Density determines how much space a given mass occupies. Different materials with the same GSM can have different thicknesses based on their density.
Q2: What is a typical GSM range for paper?
A: Standard copy paper is typically 80-100 GSM, cardstock ranges from 150-300 GSM, while heavy card can be 350-400 GSM.
Q3: How accurate is this conversion?
A: The conversion is mathematically precise when accurate density values are used. Actual measurements may vary slightly due to material compression and manufacturing variations.
Q4: Can this be used for all materials?
A: This formula works for homogeneous materials where density is consistent throughout. It may not be accurate for composite or layered materials.
Q5: How do I find the density of an unknown material?
A: Density can be measured by weighing a known volume of the material or consulting material specification sheets from manufacturers.
