About Converting Long tons per Cubic Meter to Slugs per Gallon
Long ton per Cubic Meter and Slug per Gallon both measure density — mass per unit volume — a property used to identify materials, check manufacturing quality, and predict whether something floats or sinks. As a fixed reference point, water has a density of exactly 1000 kg/m³ (1 g/cm³, 1 g/mL) at its temperature of maximum density, which is why many density figures in science and engineering are quoted relative to water. Both are mass per volume density units.
Formula
slugs per gallon = long tons per cubic meter × 0.263545396884
This factor comes from each unit's defined relationship to the category's base unit: 1 long ton per cubic meter equals 1016.0469088 base units, and 1 slug per gallon equals 3855.30129084 base units, so dividing one by the other gives the direct long ton per cubic meter-to-slug per gallon factor of 0.263545396884.
Simple example
1 long ton/m3 × 0.2635453969 = 0.2635453969 slug/gal
1 long ton per cubic meter = 0.2635453969 slugs per gallon.
Real-world example
1,000 long ton/m3 × 0.2635453969 = 263.5453969 slug/gal
1,000 long tons per cubic meter = 263.5453969 slugs per gallon.

Multiply the long ton per cubic meter value by 0.2635453969. The converter above does this instantly to whatever precision you set.
How do I convert slug per gallon back to long ton per cubic meter?
Use the reverse factor: 1 slug per gallon equals 3.794412696 long tons per cubic meter. You can also use the swap control in the converter above to flip the direction instantly.
What is a long ton per cubic meter?
Long ton per Cubic Meter (long ton/m3) is a unit of density.
What is a slug per gallon?
Slug per Gallon (slug/gal) is a unit of density.
Is the long ton per cubic meter to slug per gallon conversion exact?
Yes. Both long ton per cubic meter and slug per gallon are defined by fixed standards rather than physical artifacts, so the factor of 0.2635453969 used above is exact to as many digits as you choose to display.
What's the difference between density and mass concentration?
Density is the mass of a pure substance or material per unit volume. Mass concentration is the mass of one component — like a dissolved solute — within a mixture's total volume. The two use the same kind of units but describe different physical situations.
