About Converting Milligrams per Fluid ounce to Drams per Teaspoon
Milligram per Fluid ounce and Dram per Teaspoon 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
drams per teaspoon = milligrams per fluid ounce × 0.0000940638985322
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 dram per teaspoon equals 359.479281951 base units, so dividing one by the other gives the direct milligram per fluid ounce-to-dram per teaspoon factor of 0.0000940638985322.
Simple example
1 mg/fl oz × 0.00009406389853 = 0.0000940639 dr/tsp
1 milligram per fluid ounce = 0.0000940639 drams per teaspoon.
Real-world example
1,000 mg/fl oz × 0.00009406389853 = 0.0940638985 dr/tsp
1,000 milligrams per fluid ounce = 0.0940638985 drams per teaspoon.
