About Converting Milligrams per Gallon to Drams per Teaspoon
Milligram per Gallon 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 gallon × 7.348742e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 milligram per gallon equals 0.000264172052358 base units, and 1 dram per teaspoon equals 359.479281951 base units, so dividing one by the other gives the direct milligram per gallon-to-dram per teaspoon factor of 7.348742e-7.
Simple example
1 mg/gal × 7.348742e-7 = 7.348742e-7 dr/tsp
1 milligram per gallon = 7.348742e-7 drams per teaspoon.
Real-world example
1,000 mg/gal × 7.348742e-7 = 0.0007348742 dr/tsp
1,000 milligrams per gallon = 0.0007348742 drams per teaspoon.

Frequently asked questions
How many drams per teaspoon are in 1 milligram per gallon?
1 milligram per gallon equals 7.348742e-7 drams per teaspoon, using the exact defined conversion factor rather than an estimate.
How do I convert milligram per gallon to dram per teaspoon?
Multiply the milligram per gallon value by 7.348742e-7. The converter above does this instantly to whatever precision you set.
How do I convert dram per teaspoon back to milligram per gallon?
Use the reverse factor: 1 dram per teaspoon equals 1,360,777.11 milligrams per gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a milligram per gallon?
Milligram per Gallon (mg/gal) is a unit of density.
What is a dram per teaspoon?
Dram per Teaspoon (dr/tsp) is a unit of density.
Is the milligram per gallon to dram per teaspoon conversion exact?
Yes. Both milligram per gallon and dram per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 7.348742e-7 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.
