About Converting Pounds per Cubic Meter to Metric tons per Cubic foot
Pound per Cubic Meter and Metric 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
metric tons per cubic foot = pounds per cubic meter × 0.0000128443055566
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per cubic meter equals 0.45359237 base units, and 1 metric ton per cubic foot equals 35314.6667215 base units, so dividing one by the other gives the direct pound per cubic meter-to-metric ton per cubic foot factor of 0.0000128443055566.
Simple example
1 lb/m3 × 0.00001284430556 = 0.0000128443 t/ft3
1 pound per cubic meter = 0.0000128443 metric tons per cubic foot.
Real-world example
1,000 lb/m3 × 0.00001284430556 = 0.0128443056 t/ft3
1,000 pounds per cubic meter = 0.0128443056 metric tons per cubic foot.

Frequently asked questions
How many metric tons per cubic foot are in 1 pound per cubic meter?
1 pound per cubic meter equals 0.0000128443 metric tons per cubic foot, using the exact defined conversion factor rather than an estimate.
How do I convert pound per cubic meter to metric ton per cubic foot?
Multiply the pound per cubic meter value by 0.00001284430556. The converter above does this instantly to whatever precision you set.
How do I convert metric ton per cubic foot back to pound per cubic meter?
Use the reverse factor: 1 metric ton per cubic foot equals 77,855.51314 pounds per cubic meter. You can also use the swap control in the converter above to flip the direction instantly.
What is a pound per cubic meter?
Pound per Cubic Meter (lb/m3) is a unit of density.
What is a metric ton per cubic foot?
Metric ton per Cubic foot (t/ft3) is a unit of density.
Is the pound per cubic meter to metric ton per cubic foot conversion exact?
Yes. Both pound per cubic meter and metric ton per cubic foot are defined by fixed standards rather than physical artifacts, so the factor of 0.00001284430556 used above is exact to as many digits as you choose to display.
What's the difference between density and mass concentration?
Density is the mass of a pure substance or material per unit volume. Mass concentration is the mass of one component — like a dissolved solute — within a mixture's total volume. The two use the same kind of units but describe different physical situations.
