About Converting Pounds per Cubic foot to Metric tons per Cubic yard
Pound per Cubic foot and Metric ton per Cubic yard 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. Pound per Cubic foot is most often used for us construction material density specs (concrete, soil, lumber, insulation).
Formula
metric tons per cubic yard = pounds per cubic foot × 0.01224699399
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per cubic foot equals 16.018463374 base units, and 1 metric ton per cubic yard equals 1307.95061931 base units, so dividing one by the other gives the direct pound per cubic foot-to-metric ton per cubic yard factor of 0.01224699399.
Simple example
1 lb/ft3 × 0.01224699399 = 0.012246994 t/yd3
1 pound per cubic foot = 0.012246994 metric tons per cubic yard.
Real-world example
1,000 lb/ft3 × 0.01224699399 = 12.24699399 t/yd3
1,000 pounds per cubic foot = 12.24699399 metric tons per cubic yard.
