About Converting Drams per Teaspoon to Stones per Oil barrel
Dram per Teaspoon and Stone per Oil barrel 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
stones per oil barrel = drams per teaspoon × 9
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per teaspoon equals 359.479281951 base units, and 1 stone per oil barrel equals 39.942142439 base units, so dividing one by the other gives the direct dram per teaspoon-to-stone per oil barrel factor of 9.
Simple example
1 dr/tsp × 9 = 9 st/bbl
1 dram per teaspoon = 9 stones per oil barrel.
Real-world example
1,000 dr/tsp × 9 = 9,000 st/bbl
1,000 drams per teaspoon = 9,000 stones per oil barrel.

Frequently asked questions
How many stones per oil barrel are in 1 dram per teaspoon?
1 dram per teaspoon equals 9 stones per oil barrel, using the exact defined conversion factor rather than an estimate.
How do I convert dram per teaspoon to stone per oil barrel?
Multiply the dram per teaspoon value by 9. The converter above does this instantly to whatever precision you set.
How do I convert stone per oil barrel back to dram per teaspoon?
Use the reverse factor: 1 stone per oil barrel equals 0.1111111111 drams per teaspoon. You can also use the swap control in the converter above to flip the direction instantly.
What is a dram per teaspoon?
Dram per Teaspoon (dr/tsp) is a unit of density.
What is a stone per oil barrel?
Stone per Oil barrel (st/bbl) is a unit of density.
Is the dram per teaspoon to stone per oil barrel conversion exact?
Yes. Both dram per teaspoon and stone per oil barrel are defined by fixed standards rather than physical artifacts, so the factor of 9 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.
