About Converting Grams per Teaspoon to Grams per Gallon
Gram per Teaspoon and Gram 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
grams per gallon = grams per teaspoon × 768
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per teaspoon equals 202.884136211 base units, and 1 gram per gallon equals 0.264172052358 base units, so dividing one by the other gives the direct gram per teaspoon-to-gram per gallon factor of 768.
Simple example
1 g/tsp × 768 = 768 g/gal
1 gram per teaspoon = 768 grams per gallon.
Real-world example
1,000 g/tsp × 768 = 768,000 g/gal
1,000 grams per teaspoon = 768,000 grams per gallon.

Frequently asked questions
How many grams per gallon are in 1 gram per teaspoon?
1 gram per teaspoon equals 768 grams per gallon, using the exact defined conversion factor rather than an estimate.
How do I convert gram per teaspoon to gram per gallon?
Multiply the gram per teaspoon value by 768. The converter above does this instantly to whatever precision you set.
How do I convert gram per gallon back to gram per teaspoon?
Use the reverse factor: 1 gram per gallon equals 0.0013020833 grams per teaspoon. You can also use the swap control in the converter above to flip the direction instantly.
What is a gram per teaspoon?
Gram per Teaspoon (g/tsp) is a unit of density.
What is a gram per gallon?
Gram per Gallon (g/gal) is a unit of density.
Is the gram per teaspoon to gram per gallon conversion exact?
Yes. Both gram per teaspoon and gram per gallon are defined by fixed standards rather than physical artifacts, so the factor of 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.
