About Converting Grams per Gallon to Grams per Teaspoon
Gram per Gallon and Gram 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
grams per teaspoon = grams per gallon × 0.00130208333333
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 gram per teaspoon equals 202.884136211 base units, so dividing one by the other gives the direct gram per gallon-to-gram per teaspoon factor of 0.00130208333333.
Simple example
1 g/gal × 0.001302083333 = 0.0013020833 g/tsp
1 gram per gallon = 0.0013020833 grams per teaspoon.
Real-world example
1,000 g/gal × 0.001302083333 = 1.302083333 g/tsp
1,000 grams per gallon = 1.302083333 grams per teaspoon.

How do I convert gram per teaspoon back to gram per gallon?
Use the reverse factor: 1 gram per teaspoon equals 768 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 gram per teaspoon?
Gram per Teaspoon (g/tsp) is a unit of density.
Is the gram per gallon to gram per teaspoon conversion exact?
Yes. Both gram per gallon and gram per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 0.001302083333 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.
