Liter to Gallon (US) FAQ
Is this factor exact?
Some conversion links are exact by unit definition, while display values may be rounded for readability. Use higher precision when documenting formulas, labels, or technical specs.
Why do volume mistakes happen so often?
Volume has many similarly named units across systems. US and UK gallons differ, fluid ounces differ by system, and kitchen shorthand can hide assumptions. Verify system and abbreviation first.
How many decimals should I keep?
Recipes often use low precision, while production and lab workflows may require more. Keep a precision standard across your workflow to avoid compounding rounding differences.
