Notes on Meaning
The word "gallon" has two primary, distinct meanings based on the measurement system: 1. The US liquid gallon: Used for measuring most liquids (e.g., gasoline, milk, paint) in the United States. It is part of the US customary units system. 2. The imperial gallon: Used in the United Kingdom, Canada, and some other countries for measuring liquids and sometimes dry goods. It is larger than the US gallon.
It is crucial to specify the system (US or imperial) when precision is required, as the difference is significant (approximately 20%). In everyday conversation within a specific country, the local standard is assumed.
