# Gallon to Tons Calculator

Welcome to the gallons-to-tons calculator, a tool created to perform **volume-to-mass conversions between the different types of gallons and tons**. Use it and discover:

**How many gallons**are in any number of tons of a substance; or**How many tons**are in any gallons.

To convert between gallons and tons, we must consider the density. Therefore, to use this gallons-to-tons converter, **select the type of substance you're dealing with**. If the material is not on the list, input the density yourself.

## The formula to convert from gallons to tons

To **calculate the tons** for a number of gallons, multiply the density (in tons per gallon) by the volume of substance (the number of gallons):

For example, let's see how many tons are in 28,000 US gallons of water, whose density is 0.0041727 US ton/US gal:

🙋 You must use the same type of tons and the same type of gallons across a formula. For example, you cannot use UK gallons for the density and US gallons for the volume.

To do the opposite and **calculate the gallons** for the tons of a substance, divide the mass by the density:

For example, let's find the **gallons in 28 US tons of water**:

## Expressing density as ton/gal

You can input any density units in the gallons-to-tons calculator, which will handle them properly. Alternatively, you'll need the density expressed in tons per gallon to use the formulas above.

**To convert the density to US tons per US gallon**, you can use the following conversion factors:

**Density [ton/gal] = Density [kg/m³] × 4.1727 × 10⁻⁶**;

**Density [ton/gal] = Density [lb/ft³] × 6.68403 × 10⁻⁵**;

**Density [ton/gal] = Density [g/cm³] × 0.0041727**;

**Density [ton/gal] = Density [lb/in³] × 0.1155**;

**Density [ton/gal] = Density [lb/gal] × 0.0005**

For example, let's express the water density (62.43 lb/ft³) in terms of tons per gallon:

**Density [ton/gal] = 62.43 × 6.68403 × 10⁻⁵ ton/gal**;

**Density [ton/gal] = 0.004172 ton/gal**;
