About Converting Long tons per Oil barrel to Drams per Teaspoon
Long ton per Oil barrel and Dram per Teaspoon 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
drams per teaspoon = long tons per oil barrel × 17.7777777778
This factor comes from each unit's defined relationship to the category's base unit: 1 long ton per oil barrel equals 6390.74279023 base units, and 1 dram per teaspoon equals 359.479281951 base units, so dividing one by the other gives the direct long ton per oil barrel-to-dram per teaspoon factor of 17.7777777778.
Simple example
1 long ton/bbl × 17.77777778 = 17.77777778 dr/tsp
1 long ton per oil barrel = 17.77777778 drams per teaspoon.
Real-world example
1,000 long ton/bbl × 17.77777778 = 17,777.77778 dr/tsp
1,000 long tons per oil barrel = 17,777.77778 drams per teaspoon.
