About Converting Grams per Cubic yard to Long tons per Cubic foot
Gram per Cubic yard and Long ton 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
long tons per cubic foot = grams per cubic yard × 3.645209e-8
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per cubic yard equals 0.00130795061931 base units, and 1 long ton per cubic foot equals 35881.3579577 base units, so dividing one by the other gives the direct gram per cubic yard-to-long ton per cubic foot factor of 3.645209e-8.
Simple example
1 g/yd3 × 3.645209e-8 = 3.645209e-8 long ton/ft3
1 gram per cubic yard = 3.645209e-8 long tons per cubic foot.
Real-world example
1,000 g/yd3 × 3.645209e-8 = 0.0000364521 long ton/ft3
1,000 grams per cubic yard = 0.0000364521 long tons per cubic foot.
