Grams per square meter to kilograms per square meter
Type a value in GSM to get it in kg/m² instantly.
0.18kg/m²
That's 1.2× as heavy as a summer T-shirt, while a hoodie is 1.56× heavier. A T-shirt made from it would weigh about 198 g.
What it means
How heavy is that cloth?
Weight describes the cloth, not the garment. A loose knit at 200 GSM feels quite different from a tight weave at the same weight.
The math
How to convert GSM to kg/m²
To convert grams per square meter to kilograms per square meter, multiply by 0.001.
Example: 180 GSM × 0.001 = 0.18 kg/m².
In the other direction, 1 kg/m² = 1,000 GSM.
