- Older UK cooking and pantry measurements
- Home brewing and small batch drink volumes
- Some workshop and DIY fluid measuring
- Reading legacy labels, manuals, and documents
- Understanding Imperial gallon and quart relationships
Liter
A liter is a metric unit of volume used worldwide. Its symbol is L.
The liter is part of the metric system and is widely used in science, medicine, food, and everyday measuring. It became popular because metric units are easy to scale by powers of 10.
- Water bottles and beverage containers
- Cooking and recipe measurements in many countries
- Laboratory and chemistry volumes
- Medicine dosing and IV fluid volumes
- Fuel economy and engine fluid specifications
