What is GSM and OZ of tarp? How to convert OZ to GSM?

GSM (Grams per Square Meter) and OZ (Ounces per Square Yard) are two units used to measure the weight and thickness of tarps, helping to determine their durability and strength.

 

GSM (Grams per Square Meter)

GSM measures the weight of the tarp material per square meter of fabric.

The higher the GSM, the thicker and heavier the tarp, meaning it will generally be more durable and better at withstanding harsh weather conditions.

OZ (Ounces per Square Yard)

OZ measures the weight of the tarp material per square yard of fabric.

Like GSM, the higher the OZ, the thicker and stronger the tarp will be.

How to Convert OZ to GSM

To convert ounces per square yard (oz/yd²) to grams per square meter (GSM), you can use this formula:

GSM=OZ×33.906

Conversion Example

If a tarp has a weight of 10 oz/yd², you can calculate its GSM as follows:

GSM=10×33.906=339.06GSM

This means a 10 oz/yd² tarp weighs approximately 339 GSM.

Why Convert Between GSM and OZ?

GSM is more commonly used in European and Asian markets, while OZ is more common in the USA and Canada Converting between the two allows you to compare tarp specifications easily, no matter where you’re buying from.

In short:

GSM: Grams per Square Meter (used more globally).

OZ: Ounces per Square Yard (used mainly in the U.S.).

By understanding both units, you can select the right tarp based on the region and ensure you get the right weight and thickness for your project.
