* Thickness Varies: The thickness of pig skin can vary greatly depending on the breed of pig, its age, and how it was raised.
* Fat Content: Pork belly itself is high in fat, and this fat layer is right beneath the skin. The amount of fat can fluctuate, meaning the skin percentage is also variable.
* Processing: Some pork bellies are trimmed of excess fat and skin before being sold. Others are left intact.
General Estimation:
While an exact weight is impossible, you can roughly estimate that the skin makes up about 5-10% of the total weight of a 1kg pork belly. This means the skin would weigh between 50g and 100g.
Important Note: This is a very rough estimate. The actual weight of the skin could be significantly higher or lower.
