About Converting Long tons per Liter to Pounds per Cubic foot
Long ton per Liter and Pound per Cubic foot 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
pounds per cubic foot = long tons per liter × 63429.7363661
This factor comes from each unit's defined relationship to the category's base unit: 1 long ton per liter equals 1016046.9088 base units, and 1 pound per cubic foot equals 16.018463374 base units, so dividing one by the other gives the direct long ton per liter-to-pound per cubic foot factor of 63429.7363661.
Simple example
1 long ton/L × 63429.73637 = 63,429.73637 lb/ft3
1 long ton per liter = 63,429.73637 pounds per cubic foot.
Real-world example
1,000 long ton/L × 63429.73637 = 63,429,736.37 lb/ft3
1,000 long tons per liter = 63,429,736.37 pounds per cubic foot.

Frequently asked questions
How many pounds per cubic foot are in 1 long ton per liter?
1 long ton per liter equals 63,429.73637 pounds per cubic foot, using the exact defined conversion factor rather than an estimate.
How do I convert long ton per liter to pound per cubic foot?
Multiply the long ton per liter value by 63429.73637. The converter above does this instantly to whatever precision you set.
How do I convert pound per cubic foot back to long ton per liter?

What is a long ton per liter?
Long ton per Liter (long ton/L) is a unit of density.
What is a pound per cubic foot?
Pound per Cubic foot (lb/ft3) measures density. The US customary unit for expressing density, commonly used in construction and engineering material specifications. It is classified as a US customary density unit.
Is the long ton per liter to pound per cubic foot conversion exact?
Yes. Both long ton per liter and pound per cubic foot are defined by fixed standards rather than physical artifacts, so the factor of 63429.73637 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.
