About Converting Long tons per Cubic yard to Kilograms per Cubic foot
Long ton per Cubic yard and Kilogram per Cubic foot 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
kilograms per cubic foot = long tons per cubic yard × 37.6313669926
This factor comes from each unit's defined relationship to the category's base unit: 1 long ton per cubic yard equals 1328.93918362 base units, and 1 kilogram per cubic foot equals 35.3146667215 base units, so dividing one by the other gives the direct long ton per cubic yard-to-kilogram per cubic foot factor of 37.6313669926.
Simple example
1 long ton/yd3 × 37.63136699 = 37.63136699 kg/ft3
1 long ton per cubic yard = 37.63136699 kilograms per cubic foot.
Real-world example
1,000 long ton/yd3 × 37.63136699 = 37,631.36699 kg/ft3
1,000 long tons per cubic yard = 37,631.36699 kilograms per cubic foot.
