About Converting Drams per Cubic foot to Long tons per Cubic foot
Dram per Cubic foot and Long ton 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
long tons per cubic foot = drams per cubic foot × 0.00000174386160714
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per cubic foot equals 0.0625721225545 base units, and 1 long ton per cubic foot equals 35881.3579577 base units, so dividing one by the other gives the direct dram per cubic foot-to-long ton per cubic foot factor of 0.00000174386160714.
Simple example
1 dr/ft3 × 0.000001743861607 = 0.0000017439 long ton/ft3
1 dram per cubic foot = 0.0000017439 long tons per cubic foot.
Real-world example
1,000 dr/ft3 × 0.000001743861607 = 0.0017438616 long ton/ft3
1,000 drams per cubic foot = 0.0017438616 long tons per cubic foot.

Frequently asked questions
How many long tons per cubic foot are in 1 dram per cubic foot?
1 dram per cubic foot equals 0.0000017439 long tons per cubic foot, using the exact defined conversion factor rather than an estimate.
How do I convert dram per cubic foot to long ton per cubic foot?
Multiply the dram per cubic foot value by 0.000001743861607. The converter above does this instantly to whatever precision you set.
How do I convert long ton per cubic foot back to dram per cubic foot?
Use the reverse factor: 1 long ton per cubic foot equals 573,440 drams per cubic foot. You can also use the swap control in the converter above to flip the direction instantly.
What is a dram per cubic foot?
Dram per Cubic foot (dr/ft3) is a unit of density.
What is a long ton per cubic foot?
Long ton per Cubic foot (long ton/ft3) is a unit of density.
Is the dram per cubic foot to long ton per cubic foot conversion exact?
Yes. Both dram per cubic foot and long ton per cubic foot are defined by fixed standards rather than physical artifacts, so the factor of 0.000001743861607 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.
