About Converting Long tons per Cubic yard to Kilograms per Cup
Long ton per Cubic yard 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 yard × 0.314411377868
This factor comes from each unit's defined relationship to the category's base unit: 1 long ton per cubic yard equals 1328.93918362 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 yard-to-kilogram per cup factor of 0.314411377868.
Simple example
1 long ton/yd3 × 0.3144113779 = 0.3144113779 kg/cup
1 long ton per cubic yard = 0.3144113779 kilograms per cup.
Real-world example
1,000 long ton/yd3 × 0.3144113779 = 314.4113779 kg/cup
1,000 long tons per cubic yard = 314.4113779 kilograms per cup.

How do I convert kilogram per cup back to long ton per cubic yard?
Use the reverse factor: 1 kilogram per cup equals 3.180546476 long tons per cubic yard. You can also use the swap control in the converter above to flip the direction instantly.
What is a long ton per cubic yard?
Long ton per Cubic yard (long ton/yd3) 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 yard to kilogram per cup conversion exact?
Yes. Both long ton per cubic yard and kilogram per cup are defined by fixed standards rather than physical artifacts, so the factor of 0.3144113779 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.
