📘 Quick Explanation

A litre is a metric unit of volume used worldwide.
A gallon , on the other hand, has two versions:

  • U.S. gallon = 3.785 litres
  • U.K. (Imperial) gallon = 4.546 litres

So, to convert litres to:

  • US gallons: multiply litres × 0.264172
  • UK gallons: multiply litres × 0.219969

🌍 Fun Fact: Why Two Gallons?

The reason for the two gallon standards goes back to history. The British Imperial system was established first, and when the U.S. adopted its own system, it standardized the gallon differently. That’s why your car’s fuel economy ratings may look odd depending on whether you’re reading U.S. or U.K. data.

🧮 Example Conversion

Let’s say you have 5 litres of liquid:

  • In U.S. gallons , that’s 5×0.264172=1.320865×0.264172=1.320865×0.264172=1.32086 gallons.
  • In U.K. gallons , it’s 5×0.219969=1.099855×0.219969=1.099855×0.219969=1.09985 gallons.
