About Converting Micrograms per Teaspoon to Milligrams per Gallon
Microgram per Teaspoon and Milligram 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
milligrams per gallon = micrograms per teaspoon × 0.768
This factor comes from each unit's defined relationship to the category's base unit: 1 microgram per teaspoon equals 0.000202884136211 base units, and 1 milligram per gallon equals 0.000264172052358 base units, so dividing one by the other gives the direct microgram per teaspoon-to-milligram per gallon factor of 0.768.
Simple example
1 ug/tsp × 0.768 = 0.768 mg/gal
1 microgram per teaspoon = 0.768 milligrams per gallon.
Real-world example
1,000 ug/tsp × 0.768 = 768 mg/gal
1,000 micrograms per teaspoon = 768 milligrams per gallon.

Frequently asked questions
How many milligrams per gallon are in 1 microgram per teaspoon?
1 microgram per teaspoon equals 0.768 milligrams per gallon, using the exact defined conversion factor rather than an estimate.
How do I convert microgram per teaspoon to milligram per gallon?
Multiply the microgram per teaspoon value by 0.768. The converter above does this instantly to whatever precision you set.
How do I convert milligram per gallon back to microgram per teaspoon?
Use the reverse factor: 1 milligram per gallon equals 1.302083333 micrograms per teaspoon. You can also use the swap control in the converter above to flip the direction instantly.
What is a microgram per teaspoon?
Microgram per Teaspoon (ug/tsp) is a unit of density.
What is a milligram per gallon?
Milligram per Gallon (mg/gal) is a unit of density.
Is the microgram per teaspoon to milligram per gallon conversion exact?
Yes. Both microgram per teaspoon and milligram per gallon are defined by fixed standards rather than physical artifacts, so the factor of 0.768 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.
