A more thorough explanation:

Definition: False weight refers to a weight or measure that does not follow the rules set by the government or the usual practice in a particular place or business.

For example, if a seller uses a scale that is not calibrated properly and shows a weight that is more than the actual weight of the product, it is considered a false weight. Similarly, if a gas station pump is not calibrated correctly and shows more fuel than it actually dispenses, it is also a false weight.

False weights can be used to cheat customers and make more money for the seller. It is illegal and can result in fines or even imprisonment.
