About Converting Grams per Imperial gallon to Long tons per Cubic Meter
Gram per Imperial gallon and Long ton per Cubic Meter 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 cubic meter = grams per imperial gallon × 0.00021649517005
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per imperial gallon equals 0.219969248299 base units, and 1 long ton per cubic meter equals 1016.0469088 base units, so dividing one by the other gives the direct gram per imperial gallon-to-long ton per cubic meter factor of 0.00021649517005.
Simple example
1 g/imp gal × 0.00021649517 = 0.0002164952 long ton/m3
1 gram per imperial gallon = 0.0002164952 long tons per cubic meter.
Real-world example
1,000 g/imp gal × 0.00021649517 = 0.21649517 long ton/m3
1,000 grams per imperial gallon = 0.21649517 long tons per cubic meter.

Multiply the gram per imperial gallon value by 0.00021649517. The converter above does this instantly to whatever precision you set.
How do I convert long ton per cubic meter back to gram per imperial gallon?
Use the reverse factor: 1 long ton per cubic meter equals 4,619.040692 grams per imperial gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a gram per imperial gallon?
Gram per Imperial gallon (g/imp gal) is a unit of density.
What is a long ton per cubic meter?
Long ton per Cubic Meter (long ton/m3) is a unit of density.
Is the gram per imperial gallon to long ton per cubic meter conversion exact?
Yes. Both gram per imperial gallon and long ton per cubic meter are defined by fixed standards rather than physical artifacts, so the factor of 0.00021649517 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.
