Free Gallons to Tons Converter

Gallons to Tons Converter — Free Online Gal to Tons Calculator

The convert gallons to tons tool is a practical volume-to-weight converter that instantly translates volumes in gallons into weights in tons (or vice versa). Since gallons measure volume and tons measure mass, the conversion depends on the material's density. This free online calculator simplifies the process: select a substance from the built-in list or manually input the density if your material isn't listed. It supports US liquid gallons as well as imperial gallons and works with short tons (US), long tons (UK), and metric tons provided you keep the same unit system throughout.

How to Use the Converter

1. Choose the type of substance from the drop-down menu (e.g., water, diesel, crude oil).
2. If your substance is not available, select "Input your own density" and enter the density value in any common unit.
3. Specify whether you are converting gallons to tons or tons to gallons.
4. The calculator instantly delivers the result, handling unit conversions behind the scenes.

The Conversion Formulas

The core relationship is:

$$\text{tons} = \text{gallons} \times \text{density (tons per gallon)}$$ $$\text{gallons} = \frac{\text{tons}}{\text{density (tons per gallon)}}$$

Important: The same type of gallon and the same type of ton must be used in both the density and the quantity being converted. Mixing US gallons with a density expressed in imperial gallons per ton, for instance, will give inaccurate numbers.

Expressing Density in Tons per Gallon

If your density data comes in other units, apply the following multipliers to obtain density in US tons per US gallon:

Original Unit	Multiply by
kg/m³	$4.1727 \times 10^{-6}$
lb/ft³	$6.68403 \times 10^{-5}$
g/cm³	$0.0041727$
lb/in³	$0.1155$
lb/gal	$0.0005$

For example, water has a density of $62.43\ \text{lb/ft}^3$. Using the factor:

$$\text{density}_{\text{water}} = 62.43 \times 6.68403 \times 10^{-5} \approx 0.0041727\ \text{US ton/US gal}$$

Simple Examples

Gallons → Tons:
Suppose you have 28,000 US gallons of water.

$$\text{tons} = 28,000 \times 0.0041727 \approx 116.84\ \text{US tons}$$

So 28,000 US gallons of water weigh roughly 116.8 short tons.

Tons → Gallons:
If you have 28 US tons of water, the volume in gallons is:

$$\text{gallons} = \frac{28}{0.0041727} \approx 6,710\ \text{US gallons}$$

Thus, 28 US tons of water correspond to about 6,710 US gallons.
