Common use cases

  • Scale a recipe written in cups or fluid ounces against a metric shopping list in liters.
  • Compare fuel-tank or coolant labels that mix liters and gallons when the doc does not spell out US vs UK.
  • Translate small engine or HVAC notes between cubic feet and cubic meters for rough capacity checks.

Common mistakes to avoid

  • US gallon vs imperial (UK) gallon

    An imperial gallon is about 20% larger than a US liquid gallon. Use the UK gal column—or type UK gal—when the source is British or Commonwealth recipe text.

  • Fluid ounces vs weight ounces

    This page’s fl oz column is US fluid ounces (volume), not avoirdupois ounces used on the weight converter.

FAQ

No. Conversions run in your browser from the text you enter.

Why is bare “gallon” US liquid here?

The calculator hub uses US-style defaults for everyday measures; specify UK gal or imperial gallon when you need the larger imperial definition.
