About Converting Long tons per Cubic foot to Kilograms per Cup
Long ton per Cubic foot and Kilogram per Cup 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 cup = long tons per cubic foot × 8.48910720243
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 cup equals 4226.75283773 base units, so dividing one by the other gives the direct long ton per cubic foot-to-kilogram per cup factor of 8.48910720243.
Simple example
1 long ton/ft3 × 8.489107202 = 8.489107202 kg/cup
1 long ton per cubic foot = 8.489107202 kilograms per cup.
Real-world example
1,000 long ton/ft3 × 8.489107202 = 8,489.107202 kg/cup
1,000 long tons per cubic foot = 8,489.107202 kilograms per cup.

How do I convert kilogram per cup back to long ton per cubic foot?
Use the reverse factor: 1 kilogram per cup equals 0.1177980176 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 cup?
Kilogram per Cup (kg/cup) is a unit of density.
Is the long ton per cubic foot to kilogram per cup conversion exact?
Yes. Both long ton per cubic foot and kilogram per cup are defined by fixed standards rather than physical artifacts, so the factor of 8.489107202 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.
