About Converting Milligrams per Imperial gallon to Milligrams per Cubic yard
Milligram per Imperial gallon and Milligram 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
milligrams per cubic yard = milligrams per imperial gallon × 168.178557394
This factor comes from each unit's defined relationship to the category's base unit: 1 milligram per imperial gallon equals 0.000219969248299 base units, and 1 milligram per cubic yard equals 0.00000130795061931 base units, so dividing one by the other gives the direct milligram per imperial gallon-to-milligram per cubic yard factor of 168.178557394.
Simple example
1 mg/imp gal × 168.1785574 = 168.1785574 mg/yd3
1 milligram per imperial gallon = 168.1785574 milligrams per cubic yard.
Real-world example
1,000 mg/imp gal × 168.1785574 = 168,178.5574 mg/yd3
1,000 milligrams per imperial gallon = 168,178.5574 milligrams per cubic yard.

Multiply the milligram per imperial gallon value by 168.1785574. The converter above does this instantly to whatever precision you set.
How do I convert milligram per cubic yard back to milligram per imperial gallon?
Use the reverse factor: 1 milligram per cubic yard equals 0.0059460612 milligrams per imperial gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a milligram per imperial gallon?
Milligram per Imperial gallon (mg/imp gal) is a unit of density.
What is a milligram per cubic yard?
Milligram per Cubic yard (mg/yd3) is a unit of density.
Is the milligram per imperial gallon to milligram per cubic yard conversion exact?
Yes. Both milligram per imperial gallon and milligram per cubic yard are defined by fixed standards rather than physical artifacts, so the factor of 168.1785574 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.
