MM to GSM Calculator

Formula

The formula to calculate the GSM is:

\[ GSM = \text{Thickness (mm)} \times \text{Density (g/cm³)} \times 1000 \]

Where:

\( GSM \) is the paper or fabric weight in grams per square meter (g/m²).
\( \text{Thickness} \) is the material thickness in millimeters (mm).
\( \text{Density} \) is the material density in grams per cubic centimeter (g/cm³).

What is GSM?

GSM stands for grams per square meter and is a standard unit of measurement for the weight of paper and fabric materials. A higher GSM indicates a heavier and typically thicker material. It is an important specification for quality control in manufacturing and purchasing of paper and textile products.

Example Calculation

Consider an example where:

Thickness: 0.2 mm
Density: 0.8 g/cm³

Using the formula to calculate the GSM:

\[ GSM = 0.2 \times 0.8 \times 1000 = 160 \text{ g/m²} \]

This means that the GSM for this example is 160 g/m².
