Assumptions and limits

  • US customary units (not UK imperial) for gallons and fluid ounces

This tool provides an educational estimate. Rules, rates and personal circumstances can change the answer. Review the assumptions before relying on a result. Report a correction.

Common mistakes to avoid

  • Confusing fluid ounces (volume) with ounces (weight).
  • Using US customary gallons when the calculation requires UK imperial gallons — they differ by 20%.
  • Forgetting to account for both multiplication and offset in temperature conversions.
