### What is GSM (Grams Per Square Meter) Calculator?

A GSM calculator is a tool used to calculate the weight per unit area of a material. The weight is measured in grams and the area in square meters. This value is commonly used in the textile and paper industry to determine the density of materials such as fabrics, paper, and cardboard.

### Formula

The formula used to calculate the GSM is:

GSM = Wg * 10,000 / (L * W)

Where:

- GSM = Grams per square meter
- Wg = Weight of the material in grams
- L = Length of the material in meters
- W = Width of the material in meters

### Example

Let’s say we have a fabric with a weight of 100 grams, a length of 2 meters, and a width of 1 meter. Using the formula above, we can calculate the GSM as follows:

GSM = 100 * 10,000 / (2 * 1)

GSM = 50,000 / 2

GSM = 25,000 g/m²

So the GSM of this fabric is 25,000 grams per square meter.

### How to Calculate GSM

To use a GSM calculator, you need to measure the weight, length, and width of the material you want to calculate the GSM for. Then, simply enter these values into the calculator and it will automatically calculate the GSM for you using the formula above.

### FAQs

1. What is GSM used for?

GSM is commonly used in the textile and paper industry to determine the density of materials such as fabrics, paper, and cardboard.

2. What is a good GSM for a fabric?

The GSM of a fabric can vary depending on the intended use. For example, a lightweight fabric may have a GSM of around 50-100, while a heavy-duty fabric may have a GSM of 500 or more.

3. Can I calculate GSM using a scale?

Yes, you can calculate the weight of a material using a scale, but you will also need to measure the length and width of the material to calculate the GSM using the formula above.
