About Converting Ounces per Cubic yard to Milligrams per Imperial gallon
Ounce per Cubic yard and Milligram per Imperial gallon 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 imperial gallon = ounces per cubic yard × 168.56800037
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per cubic yard equals 0.0370797763286 base units, and 1 milligram per imperial gallon equals 0.000219969248299 base units, so dividing one by the other gives the direct ounce per cubic yard-to-milligram per imperial gallon factor of 168.56800037.
Simple example
1 oz/yd3 × 168.5680004 = 168.5680004 mg/imp gal
1 ounce per cubic yard = 168.5680004 milligrams per imperial gallon.
Real-world example
1,000 oz/yd3 × 168.5680004 = 168,568.0004 mg/imp gal
1,000 ounces per cubic yard = 168,568.0004 milligrams per imperial gallon.
