About Converting Nanograms per Teaspoon to Grams per Gallon
Nanogram 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 = nanograms per teaspoon × 7.68e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 nanogram per teaspoon equals 2.028841e-7 base units, and 1 gram per gallon equals 0.264172052358 base units, so dividing one by the other gives the direct nanogram per teaspoon-to-gram per gallon factor of 7.68e-7.
Simple example
1 ng/tsp × 7.68e-7 = 7.68e-7 g/gal
1 nanogram per teaspoon = 7.68e-7 grams per gallon.
Real-world example
1,000 ng/tsp × 7.68e-7 = 0.000768 g/gal
1,000 nanograms per teaspoon = 0.000768 grams per gallon.

Frequently asked questions
How many grams per gallon are in 1 nanogram per teaspoon?
1 nanogram per teaspoon equals 7.68e-7 grams per gallon, using the exact defined conversion factor rather than an estimate.
How do I convert nanogram per teaspoon to gram per gallon?
Multiply the nanogram per teaspoon value by 7.68e-7. The converter above does this instantly to whatever precision you set.
How do I convert gram per gallon back to nanogram per teaspoon?
Use the reverse factor: 1 gram per gallon equals 1,302,083.333 nanograms per teaspoon. You can also use the swap control in the converter above to flip the direction instantly.
What is a nanogram per teaspoon?
Nanogram per Teaspoon (ng/tsp) is a unit of density.
What is a gram per gallon?
Gram per Gallon (g/gal) is a unit of density.
Is the nanogram per teaspoon to gram per gallon conversion exact?
Yes. Both nanogram per teaspoon and gram per gallon are defined by fixed standards rather than physical artifacts, so the factor of 7.68e-7 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.
