Paper Weight Conversion Chart (GSM, MM, PT, Inches)

With the help of this blog, you can convert the thickness in any unit of your choice, such as 0.8mm to inches, 0.49mm to cm, mm to pt, mm to gsm, inches to pt, and inches to gsm. To convert the paper thickness in mm to pt with the help of this formula.

1 millimeter (MM) = 2.83465 points (PT)

Inches into PT formula = (1 inch = 72 points (PT))

To convert the paper weight from mm to gsm, you can use this formula to find the right values:

GSM=Density (kg/m3) × Thickness (mm)1000\text{GSM} = \frac{\text{Density (kg/m}^3\text{) × Thickness (mm)}}{1000}

GSM=1000 Density (kg/m3) × Thickness (mm)​
