About Converting Drams per Milliliter to Long tons per Fluid ounce
Dram per Milliliter and Long ton per Fluid ounce 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 fluid ounce = drams per milliliter × 0.0000515721427917
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per milliliter equals 1771.84519531 base units, and 1 long ton per fluid ounce equals 34356633.2403 base units, so dividing one by the other gives the direct dram per milliliter-to-long ton per fluid ounce factor of 0.0000515721427917.
Simple example
1 dr/mL × 0.00005157214279 = 0.0000515721 long ton/fl oz
1 dram per milliliter = 0.0000515721 long tons per fluid ounce.
Real-world example
1,000 dr/mL × 0.00005157214279 = 0.0515721428 long ton/fl oz
1,000 drams per milliliter = 0.0515721428 long tons per fluid ounce.

Frequently asked questions
How many long tons per fluid ounce are in 1 dram per milliliter?
1 dram per milliliter equals 0.0000515721 long tons per fluid ounce, using the exact defined conversion factor rather than an estimate.
How do I convert dram per milliliter to long ton per fluid ounce?
Multiply the dram per milliliter value by 0.00005157214279. The converter above does this instantly to whatever precision you set.
How do I convert long ton per fluid ounce back to dram per milliliter?
Use the reverse factor: 1 long ton per fluid ounce equals 19,390.31318 drams per milliliter. You can also use the swap control in the converter above to flip the direction instantly.
What is a dram per milliliter?
Dram per Milliliter (dr/mL) is a unit of density.
What is a long ton per fluid ounce?
Long ton per Fluid ounce (long ton/fl oz) is a unit of density.
Is the dram per milliliter to long ton per fluid ounce conversion exact?
Yes. Both dram per milliliter and long ton per fluid ounce are defined by fixed standards rather than physical artifacts, so the factor of 0.00005157214279 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.
