About Converting Long tons per Oil barrel to US hundredweights per Cup
Long ton per Oil barrel and US hundredweight per Cup 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
us hundredweights per cup = long tons per oil barrel × 0.0333333333333
