Enter the weight of the paper in grams per square meter (GSM) and the density of the paper (D) into the calculator to determine the thickness of the paper (T). This calculator can also evaluate any of the variables given the others are known.
| GSM to Thickness | Thickness to GSM |
|---|---|
| 60 gsm = 0.0750 mm | 0.050 mm = 40 gsm |
| 70 gsm = 0.0875 mm | 0.080 mm = 64 gsm |
| 80 gsm = 0.1000 mm | 0.090 mm = 72 gsm |
| 90 gsm = 0.1125 mm | 0.110 mm = 88 gsm |
| 100 gsm = 0.1250 mm | 0.140 mm = 112 gsm |
| 120 gsm = 0.1500 mm | 0.180 mm = 144 gsm |
| 130 gsm = 0.1625 mm | 0.200 mm = 160 gsm |
| 150 gsm = 0.1875 mm | 0.240 mm = 192 gsm |
| 200 gsm = 0.2500 mm | 0.300 mm = 240 gsm |
| 250 gsm = 0.3125 mm | 0.400 mm = 320 gsm |
| Formulas (using density in g/cm³): Thickness (mm) = GSM ÷ (Density × 1000) and GSM = Density × 1000 × Thickness (mm). | |
| GSM to Thickness | Thickness to GSM |
|---|---|
| 30 gsm = 0.0300 mm | 0.010 mm = 10 gsm |
| 50 gsm = 0.0500 mm | 0.012 mm = 12 gsm |
| 75 gsm = 0.0750 mm | 0.020 mm = 20 gsm |
| 100 gsm = 0.1000 mm | 0.025 mm = 25 gsm |
| 150 gsm = 0.1500 mm | 0.040 mm = 40 gsm |
| 200 gsm = 0.2000 mm | 0.060 mm = 60 gsm |
| 250 gsm = 0.2500 mm | 0.080 mm = 80 gsm |
| 300 gsm = 0.3000 mm | 0.125 mm = 125 gsm |
| 400 gsm = 0.4000 mm | 0.175 mm = 175 gsm |
| 500 gsm = 0.5000 mm | 0.225 mm = 225 gsm |
| Formulas (using density in g/cm³): Thickness (mm) = GSM ÷ (Density × 1000) and GSM = Density × 1000 × Thickness (mm). | |

Gsm To Mm Formula
The following formula is used to calculate the thickness of paper in millimeters (MM) from its weight in grams per square meter (GSM).
T = (GSM / D) * 0.001
Variables:
- T is the thickness of the paper (MM)
- GSM is the weight of the paper in grams per square meter (GSM)
- D is the density of the paper (g/cm³)
To calculate the thickness of the paper, divide the weight of the paper (GSM) by its density (D). Then, multiply the result by 0.001 to convert the unit from meters to millimeters.
What is a Gsm To Mm?
GSM to MM refers to the conversion from grams per square meter (GSM) to millimeters (MM). GSM is a metric used to measure the weight and thickness of paper, while MM is a unit used to measure length or thickness. The conversion is often used in the paper industry to determine the thickness of paper or other materials. However, the conversion is not straightforward as it also depends on the density of the material.
