About Converting Grains per Oil barrel to Carats per Tablespoon
Grain per Oil barrel and Carat per Tablespoon 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
carats per tablespoon = grains per oil barrel × 0.000030133421689
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per oil barrel equals 0.00040757288203 base units, and 1 carat per tablespoon equals 13.5256090807 base units, so dividing one by the other gives the direct grain per oil barrel-to-carat per tablespoon factor of 0.000030133421689.
Simple example
1 gr/bbl × 0.00003013342169 = 0.0000301334 ct/tbsp
1 grain per oil barrel = 0.0000301334 carats per tablespoon.
Real-world example
1,000 gr/bbl × 0.00003013342169 = 0.0301334217 ct/tbsp
1,000 grains per oil barrel = 0.0301334217 carats per tablespoon.

What is a grain per oil barrel?
Grain per Oil barrel (gr/bbl) is a unit of density.
What is a carat per tablespoon?
Carat per Tablespoon (ct/tbsp) is a unit of density.
Is the grain per oil barrel to carat per tablespoon conversion exact?
Yes. Both grain per oil barrel and carat per tablespoon are defined by fixed standards rather than physical artifacts, so the factor of 0.00003013342169 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.
