The e symbol on foods stands for estimated. On foods, the e symbol is used to ensure the consumer is fully aware that the weight is estimated. Basically, the weight on the packet is an average weight as all machines have a small margin of inaccuracy. Therefore, an e symbol is used on the packaging to represent that the weight is estimated. The weights have to be within these margins:
|Amount (g or ml) between||Accepted margin|
For example, if the food packaging stated 35g, the food must be within 9% which is 31.85g—38.15g.
It is used to ensure that the consumer knows the weight of the product may not be exactly the same as the weight indicated on the packaging. The e symbol is only used in Europe.
