About Converting Milligrams per Fluid ounce to Stones per Gallon
Milligram per Fluid ounce and Stone per 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
stones per gallon = milligrams per fluid ounce × 0.0000201565496855
This factor comes from each unit's defined relationship to the category's base unit: 1 milligram per fluid ounce equals 0.0338140227018 base units, and 1 stone per gallon equals 1677.56998244 base units, so dividing one by the other gives the direct milligram per fluid ounce-to-stone per gallon factor of 0.0000201565496855.
Simple example
1 mg/fl oz × 0.00002015654969 = 0.0000201565 st/gal
