About Converting Long tons per Cubic foot to Kilograms per Gallon
Long ton per Cubic foot and Kilogram 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
kilograms per gallon = long tons per cubic foot × 135.825715239
This factor comes from each unit's defined relationship to the category's base unit: 1 long ton per cubic foot equals 35881.3579577 base units, and 1 kilogram per gallon equals 264.172052358 base units, so dividing one by the other gives the direct long ton per cubic foot-to-kilogram per gallon factor of 135.825715239.
Simple example
1 long ton/ft3 × 135.8257152 = 135.8257152 kg/gal
1 long ton per cubic foot = 135.8257152 kilograms per gallon.
Real-world example
1,000 long ton/ft3 × 135.8257152 = 135,825.7152 kg/gal
1,000 long tons per cubic foot = 135,825.7152 kilograms per gallon.

Understanding the Long ton per Cubic foot (long ton/ft3)
Mass per volume density.
Understanding the Kilogram per Gallon
Kilogram per Gallon (kg/gal) measures density. A mathematically valid way to express liquid density in kilograms per US gallon. It is classified as a mixed metric/US customary density unit.
Uses of the Kilogram per Gallon today
- Can be used to express liquid density such as fuel or industrial liquids in kilograms per gallon — in practice, kilograms per liter (metric) and pounds per gallon (US customary) are the specific pairings more commonly seen in fuel and liquid-density references
Kilogram per Gallon — sources
- Fuel and petroleum liquid-density references — Liquid density figures for fuels are typically reported in kg/L, kg/m³, or lb/gal rather than kg/gal.

Frequently asked questions
How many kilograms per gallon are in 1 long ton per cubic foot?
1 long ton per cubic foot equals 135.8257152 kilograms per gallon, using the exact defined conversion factor rather than an estimate.
How do I convert long ton per cubic foot to kilogram per gallon?
Multiply the long ton per cubic foot value by 135.8257152. The converter above does this instantly to whatever precision you set.
How do I convert kilogram per gallon back to long ton per cubic foot?
Use the reverse factor: 1 kilogram per gallon equals 0.0073623761 long tons per cubic foot. You can also use the swap control in the converter above to flip the direction instantly.
What is a long ton per cubic foot?
Long ton per Cubic foot (long ton/ft3) is a unit of density.
What is a kilogram per gallon?
Kilogram per Gallon (kg/gal) measures density. A mathematically valid way to express liquid density in kilograms per US gallon. It is classified as a mixed metric/US customary density unit.
Is the long ton per cubic foot to kilogram per gallon conversion exact?
