GSM to Inches Formula:
| From: | To: |
The GSM to Inches conversion calculates the thickness (caliper) of materials based on their basis weight (GSM) and density. This is particularly useful in paper, fabric, and packaging industries where material thickness is a critical specification.
The calculator uses the thickness conversion formula:
Where:
Explanation: The formula converts the area-based weight measurement (GSM) to a linear thickness measurement by accounting for the material's density and unit conversions.
Details: Accurate thickness calculation is essential for quality control, material specification, manufacturing processes, and ensuring products meet required standards in various industries including paper manufacturing, textiles, and packaging.
Tips: Enter GSM value in g/m² and material density in g/cm³. Common material densities: paper (0.7-1.2 g/cm³), cardboard (0.6-0.8 g/cm³), plastic films (0.9-1.4 g/cm³). All values must be positive numbers.
Q1: What is GSM?
A: GSM stands for Grams per Square Meter, a metric measurement of paper or fabric weight and thickness.
Q2: Why is density important in this calculation?
A: Density determines how much space the material occupies. Different materials with the same GSM can have different thicknesses based on their density.
Q3: What are typical GSM values for common materials?
A: Copy paper: 80 GSM, Cardstock: 200-300 GSM, Business cards: 300-400 GSM, Magazine covers: 150-250 GSM.
Q4: Can I use this calculator for all materials?
A: Yes, as long as you know the material's GSM and density. The formula works for paper, cardboard, plastic films, fabrics, and other sheet materials.
Q5: How accurate is this conversion?
A: The conversion is mathematically accurate, but actual thickness may vary due to material compression, surface texture, and manufacturing variations.
