Frequently asked questions
- When should I use litres instead of US gallons?
- Litres in Europe and metric recipes. US gallons for US fuel tanks, prices at the pump and American labels (1 US gal ≈ 3.785 l).
- Can the result be negative?
- No — volume is positive. A negative number is almost always a typo.
- How precise is the result?
- US liquid gallon, not the larger UK imperial gallon (≈4.546 l). The factor is fixed.
- What is the most common input mistake?
- Using the UK imperial gallon instead of the US gallon — about 20% difference.
