About Converting Imperial hundredweights per Gallon to Stones per Oil barrel
Imperial hundredweight per Gallon 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 = imperial hundredweights per gallon × 336
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial hundredweight per gallon equals 13420.5598595 base units, and 1 stone per oil barrel equals 39.942142439 base units, so dividing one by the other gives the direct imperial hundredweight per gallon-to-stone per oil barrel factor of 336.
Simple example
1 long cwt/gal × 336 = 336 st/bbl
1 imperial hundredweight per gallon = 336 stones per oil barrel.
Real-world example
1,000 long cwt/gal × 336 = 336,000 st/bbl
1,000 imperial hundredweights per gallon = 336,000 stones per oil barrel.

What is a imperial hundredweight per gallon?
Imperial hundredweight per Gallon (long cwt/gal) 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 imperial hundredweight per gallon to stone per oil barrel conversion exact?
Yes. Both imperial hundredweight per gallon and stone per oil barrel are defined by fixed standards rather than physical artifacts, so the factor of 336 used above is exact to as many digits as you choose to display.
