About Converting Megagrams per Teaspoon to Stones per Gallon
Megagram per Teaspoon 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 = megagrams per teaspoon × 120939.298113
This factor comes from each unit's defined relationship to the category's base unit: 1 megagram per teaspoon equals 202884136.211 base units, and 1 stone per gallon equals 1677.56998244 base units, so dividing one by the other gives the direct megagram per teaspoon-to-stone per gallon factor of 120939.298113.
Simple example
1 Mg/tsp × 120939.2981 = 120,939.2981 st/gal
1 megagram per teaspoon = 120,939.2981 stones per gallon.
Real-world example
1,000 Mg/tsp × 120939.2981 = 120,939,298.1 st/gal
1,000 megagrams per teaspoon = 120,939,298.1 stones per gallon.

How do I convert stone per gallon back to megagram per teaspoon?
Use the reverse factor: 1 stone per gallon equals 0.0000082686 megagrams per teaspoon. You can also use the swap control in the converter above to flip the direction instantly.
What is a megagram per teaspoon?
Megagram per Teaspoon (Mg/tsp) is a unit of density.
What is a stone per gallon?
Stone per Gallon (st/gal) is a unit of density.
Is the megagram per teaspoon to stone per gallon conversion exact?
Yes. Both megagram per teaspoon and stone per gallon are defined by fixed standards rather than physical artifacts, so the factor of 120939.2981 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.
