About Converting Pounds per Cubic Meter to Megagrams per Cubic yard
Pound per Cubic Meter and Megagram 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. Both are mass per volume density units.
Formula
megagrams per cubic yard = pounds per cubic meter × 0.000346796250028
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 megagram per cubic yard equals 1307.95061931 base units, so dividing one by the other gives the direct pound per cubic meter-to-megagram per cubic yard factor of 0.000346796250028.
Simple example
1 lb/m3 × 0.00034679625 = 0.0003467963 Mg/yd3
1 pound per cubic meter = 0.0003467963 megagrams per cubic yard.
Real-world example
1,000 lb/m3 × 0.00034679625 = 0.34679625 Mg/yd3
1,000 pounds per cubic meter = 0.34679625 megagrams per cubic yard.

Frequently asked questions
How many megagrams per cubic yard are in 1 pound per cubic meter?
1 pound per cubic meter equals 0.0003467963 megagrams per cubic yard, using the exact defined conversion factor rather than an estimate.
How do I convert pound per cubic meter to megagram per cubic yard?
Multiply the pound per cubic meter value by 0.00034679625. The converter above does this instantly to whatever precision you set.
How do I convert megagram per cubic yard back to pound per cubic meter?
Use the reverse factor: 1 megagram per cubic yard equals 2,883.537524 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 megagram per cubic yard?
Megagram per Cubic yard (Mg/yd3) is a unit of density.
Is the pound per cubic meter to megagram per cubic yard conversion exact?
Yes. Both pound per cubic meter and megagram per cubic yard are defined by fixed standards rather than physical artifacts, so the factor of 0.00034679625 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.
