About Converting Troy ounces per Fluid ounce to Milligrams per Fluid ounce
Troy ounce per Fluid ounce and Milligram per Fluid ounce 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 fluid ounce = troy ounces per fluid ounce × 31103.4768
This factor comes from each unit's defined relationship to the category's base unit: 1 troy ounce per fluid ounce equals 1051.73367062 base units, and 1 milligram per fluid ounce equals 0.0338140227018 base units, so dividing one by the other gives the direct troy ounce per fluid ounce-to-milligram per fluid ounce factor of 31103.4768.
Simple example
1 oz t/fl oz × 31103.4768 = 31,103.4768 mg/fl oz
1 troy ounce per fluid ounce = 31,103.4768 milligrams per fluid ounce.
Real-world example
1,000 oz t/fl oz × 31103.4768 = 31,103,476.8 mg/fl oz
1,000 troy ounces per fluid ounce = 31,103,476.8 milligrams per fluid ounce.
