About Converting Milligrams per Teaspoon to Micrograms per Gallon
Milligram per Teaspoon and Microgram 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
micrograms per gallon = milligrams per teaspoon × 768000
This factor comes from each unit's defined relationship to the category's base unit: 1 milligram per teaspoon equals 0.202884136211 base units, and 1 microgram per gallon equals 2.641721e-7 base units, so dividing one by the other gives the direct milligram per teaspoon-to-microgram per gallon factor of 768000.
Simple example
1 mg/tsp × 768000 = 768,000 ug/gal
1 milligram per teaspoon = 768,000 micrograms per gallon.
Real-world example
1,000 mg/tsp × 768000 = 768,000,000 ug/gal
1,000 milligrams per teaspoon = 768,000,000 micrograms per gallon.

Frequently asked questions
How many micrograms per gallon are in 1 milligram per teaspoon?
1 milligram per teaspoon equals 768,000 micrograms per gallon, using the exact defined conversion factor rather than an estimate.
How do I convert milligram per teaspoon to microgram per gallon?
Multiply the milligram per teaspoon value by 768000. The converter above does this instantly to whatever precision you set.
How do I convert microgram per gallon back to milligram per teaspoon?
Use the reverse factor: 1 microgram per gallon equals 0.0000013021 milligrams per teaspoon. You can also use the swap control in the converter above to flip the direction instantly.
What is a milligram per teaspoon?
Milligram per Teaspoon (mg/tsp) is a unit of density.
What is a microgram per gallon?
Microgram per Gallon (ug/gal) is a unit of density.
Is the milligram per teaspoon to microgram per gallon conversion exact?
Yes. Both milligram per teaspoon and microgram per gallon are defined by fixed standards rather than physical artifacts, so the factor of 768000 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.
