How to check carton box GSM?

To check a carton box's GSM (Grams per Square Meter), you cut a precise sample (like 10x10 cm), weigh it on a digital scale, and then use the formula GSM = (Weight in grams / Area in m²), or simply multiply the sample weight by 100 if using a 10x10 cm (0.01 m²) cut to get grams per square meter, remembering to separate and measure layers for corrugated board.
