Grams per square meter to mommes

Type a value in GSM to get it in mm instantly.

41.81mm

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
