About Converting Pounds per Quart to Long tons per Cubic Centimeter
Pound per Quart and Long ton per Cubic Centimeter 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 centimeter = pounds per quart × 4.717358e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per quart equals 479.305709268 base units, and 1 long ton per cubic centimeter equals 1016046908.8 base units, so dividing one by the other gives the direct pound per quart-to-long ton per cubic centimeter factor of 4.717358e-7.
Simple example
1 lb/qt × 4.717358e-7 = 4.717358e-7 long ton/cm3
1 pound per quart = 4.717358e-7 long tons per cubic centimeter.
Real-world example
1,000 lb/qt × 4.717358e-7 = 0.0004717358 long ton/cm3
1,000 pounds per quart = 0.0004717358 long tons per cubic centimeter.

What is a pound per quart?
Pound per Quart (lb/qt) is a unit of density.
What is a long ton per cubic centimeter?
Long ton per Cubic Centimeter (long ton/cm3) is a unit of density.
Is the pound per quart to long ton per cubic centimeter conversion exact?
Yes. Both pound per quart and long ton per cubic centimeter are defined by fixed standards rather than physical artifacts, so the factor of 4.717358e-7 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.
