About Converting Hectograms per Cubic foot to Long tons per Imperial gallon
Hectogram per Cubic foot and Long ton per Imperial 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
long tons per imperial gallon = hectograms per cubic foot × 0.0000158008111481
This factor comes from each unit's defined relationship to the category's base unit: 1 hectogram per cubic foot equals 3.53146667215 base units, and 1 long ton per imperial gallon equals 223499.074765 base units, so dividing one by the other gives the direct hectogram per cubic foot-to-long ton per imperial gallon factor of 0.0000158008111481.
Simple example
1 hg/ft3 × 0.00001580081115 = 0.0000158008 long ton/imp gal
1 hectogram per cubic foot = 0.0000158008 long tons per imperial gallon.
Real-world example
1,000 hg/ft3 × 0.00001580081115 = 0.0158008112 long ton/imp gal
1,000 hectograms per cubic foot = 0.0158008112 long tons per imperial gallon.

Frequently asked questions
How many long tons per imperial gallon are in 1 hectogram per cubic foot?
1 hectogram per cubic foot equals 0.0000158008 long tons per imperial gallon, using the exact defined conversion factor rather than an estimate.
How do I convert hectogram per cubic foot to long ton per imperial gallon?
Multiply the hectogram per cubic foot value by 0.00001580081115. The converter above does this instantly to whatever precision you set.
How do I convert long ton per imperial gallon back to hectogram per cubic foot?
Use the reverse factor: 1 long ton per imperial gallon equals 63,287.89014 hectograms per cubic foot. You can also use the swap control in the converter above to flip the direction instantly.
What is a hectogram per cubic foot?
Hectogram per Cubic foot (hg/ft3) is a unit of density.
What is a long ton per imperial gallon?
Long ton per Imperial gallon (long ton/imp gal) is a unit of density.
Is the hectogram per cubic foot to long ton per imperial gallon conversion exact?
Yes. Both hectogram per cubic foot and long ton per imperial gallon are defined by fixed standards rather than physical artifacts, so the factor of 0.00001580081115 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.
