🚢 Gallons → Metric Tons Converter
Estimate cargo weight from tank volume.
Perfect for logistics, shipping, and environmental reporting where liquids are stored or transported by volume but weighed in metric tons.
Pure water at ~4°C.
Metric tons: 9.463529 t
Kilograms: 9,463.52946 kg
Pounds: 20,863.51113 lb
How to Use This Calculator
Enter volume
Input the tank or shipment capacity in U.S. gallons.
Specify density
Select a preset fluid or provide custom density in grams per cubic centimeter.
Review mass results
Metric tons, kilograms, and pounds appear instantly for manifests and compliance reports.
Formula
Cubic centimeters = Gallons × 3,785.411784
Mass (grams) = Volume (cc) × Density (g/cc)
Kilograms = Grams ÷ 1,000
Metric Tons = Kilograms ÷ 1,000
Use the formula breakdown to confirm the calculation logic or perform the conversion manually if needed.
Full Description
Liquid cargo is frequently measured by volume, yet shipping regulations and billing often use mass in metric tons. This calculator combines both by applying material density.
Densities vary with temperature and composition, so always use a value that matches the actual product and conditions.
Pounds are included to support legacy imperial documentation alongside SI units.
Frequently Asked Questions
Are these metric tons or short tons?
The tool outputs metric tons (tonnes). Convert to short tons by multiplying metric tons by 1.10231 if needed.
Does this account for tank size or shape?
No. It assumes you already know the volume in gallons. It converts that volume to mass using density.
Can I include temperature compensation?
Enter the density measured at your operating temperature. Adjusting for temperature is outside the scope of this calculator.
What about Imperial gallons?
Convert Imperial gallons to U.S. gallons (×1.20095) before using this tool, or extend the converter to support additional units.
