About Converting Grams per Gallon to Micrograms per Teaspoon
Gram per Gallon and Microgram 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
micrograms per teaspoon = grams per gallon × 1302.08333333
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per gallon equals 0.264172052358 base units, and 1 microgram per teaspoon equals 0.000202884136211 base units, so dividing one by the other gives the direct gram per gallon-to-microgram per teaspoon factor of 1302.08333333.
Simple example
1 g/gal × 1302.083333 = 1,302.083333 ug/tsp
1 gram per gallon = 1,302.083333 micrograms per teaspoon.
Real-world example
1,000 g/gal × 1302.083333 = 1,302,083.333 ug/tsp
1,000 grams per gallon = 1,302,083.333 micrograms per teaspoon.

Frequently asked questions
How many micrograms per teaspoon are in 1 gram per gallon?
1 gram per gallon equals 1,302.083333 micrograms per teaspoon, using the exact defined conversion factor rather than an estimate.
How do I convert gram per gallon to microgram per teaspoon?
Multiply the gram per gallon value by 1302.083333. The converter above does this instantly to whatever precision you set.
How do I convert microgram per teaspoon back to gram per gallon?
Use the reverse factor: 1 microgram per teaspoon equals 0.000768 grams per gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a gram per gallon?
Gram per Gallon (g/gal) is a unit of density.
What is a microgram per teaspoon?
Microgram per Teaspoon (ug/tsp) is a unit of density.
Is the gram per gallon to microgram per teaspoon conversion exact?
Yes. Both gram per gallon and microgram per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 1302.083333 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.
