🧪 Kilograms to Gallons Converter
Translate liquid mass (kg) into volume (gallons) using density factors for common fluids.
Choose a fluid—or provide a custom kilograms-per-gallon value—to convert between mass and volume. Ideal for inventory management, recipe scaling, and transport planning.

How to Use This Calculator
Select a fluid density
Choose from common options or input your own kilograms-per-gallon value for specialised liquids.
Enter mass or volume
Type the mass in kilograms or the volume in gallons. The other field updates automatically.
Use supporting units
Reference pounds and liters for regulatory forms, shipping labels, or recipe conversions that require both unit systems.
Formula
Gallons = Kilograms ÷ Density (kg/gal)
Kilograms = Gallons × Density (kg/gal)
Density varies with temperature and composition. Use supplier data for critical calculations.
Use the formula breakdown to confirm the calculation logic or perform the conversion manually if needed.
Full Description
Liquids are often sold by weight but stored or dosed by volume. This converter handles the bridge by applying a kilograms-per-gallon factor. It is particularly useful for chemical handling, beverage production, fuel logistics, and environmental reporting.
Because density changes with temperature, always verify the proper kg/gal value for your operating conditions. When exact data is unavailable, the provided reference values offer reliable estimates for planning purposes.
Combine this calculator with the Gallons to Pounds Converter, Gallon Calculator, or Drops to mL Converter to navigate complex workflows that mix unit systems.
Frequently Asked Questions
Does this tool use metric tonnes?
It converts between kilograms, pounds, and US gallons. For metric tonnes, divide kilograms by 1,000 after conversion.
Can I convert dry goods?
The calculator assumes liquids with consistent density. For dry bulk materials, use a bulk density (kg per cubic meter or lb per cubic foot) converter instead.
What if my liquid is temperature-sensitive?
Enable the custom density option and input the kg/gal value corresponding to your liquid’s temperature from a lab or supplier specification.
Is this accurate for honey and syrups?
The honey option provides a typical density. For precise confectionery work, measure density at your specific temperature.
