About Converting Ounces per Imperial gallon to Milligrams per Teaspoon
Ounce per Imperial gallon and Milligram 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
milligrams per teaspoon = ounces per imperial gallon × 30.7368698603
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per imperial gallon equals 6.23602329144 base units, and 1 milligram per teaspoon equals 0.202884136211 base units, so dividing one by the other gives the direct ounce per imperial gallon-to-milligram per teaspoon factor of 30.7368698603.
Simple example
1 oz/imp gal × 30.73686986 = 30.73686986 mg/tsp
1 ounce per imperial gallon = 30.73686986 milligrams per teaspoon.
Real-world example
1,000 oz/imp gal × 30.73686986 = 30,736.86986 mg/tsp
1,000 ounces per imperial gallon = 30,736.86986 milligrams per teaspoon.

What is a ounce per imperial gallon?
Ounce per Imperial gallon (oz/imp gal) is a unit of density.
What is a milligram per teaspoon?
Milligram per Teaspoon (mg/tsp) is a unit of density.
Is the ounce per imperial gallon to milligram per teaspoon conversion exact?
Yes. Both ounce per imperial gallon and milligram per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 30.73686986 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.
