Enter the thickness in millimeters and the density in grams per cubic centimeter into the calculator to determine the GSM (grams per square meter). GSM is a measure of paper weight and is used in the paper and fabric industries.
mm to GSM Formula
The following formula is used to convert thickness in millimeters to GSM:
GSM = Thickness (mm) * Density (g/cm³) * 1000
Variables:
- GSM is the paper or fabric weight in grams per square meter (g/m²)
- Thickness is the material thickness in millimeters (mm)
- Density is the material density in grams per cubic centimeter (g/cm³)
To calculate GSM, multiply the thickness of the material in millimeters by the density in grams per cubic centimeter and then by 1000 to convert to grams per square meter.
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.
How to Calculate GSM from mm?
The following steps outline how to calculate GSM from mm:
- First, determine the thickness of the material in millimeters (mm).
- Next, determine the density of the material in grams per cubic centimeter (g/cm³).
- Use the formula GSM = Thickness (mm) * Density (g/cm³) * 1000.
- Finally, calculate the GSM (g/m²).
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
Thickness (mm) = 0.2 mm
Density (g/cm³) = 0.8 g/cm³
