About Converting Picograms per Teaspoon to Centigrams per Gallon
Picogram per Teaspoon and Centigram 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
centigrams per gallon = picograms per teaspoon × 7.68e-8
This factor comes from each unit's defined relationship to the category's base unit: 1 picogram per teaspoon equals 2.028841e-10 base units, and 1 centigram per gallon equals 0.00264172052358 base units, so dividing one by the other gives the direct picogram per teaspoon-to-centigram per gallon factor of 7.68e-8.
Simple example
1 pg/tsp × 7.68e-8 = 7.68e-8 cg/gal
1 picogram per teaspoon = 7.68e-8 centigrams per gallon.
Real-world example
1,000 pg/tsp × 7.68e-8 = 0.0000768 cg/gal
1,000 picograms per teaspoon = 0.0000768 centigrams per gallon.

Frequently asked questions
How many centigrams per gallon are in 1 picogram per teaspoon?
1 picogram per teaspoon equals 7.68e-8 centigrams per gallon, using the exact defined conversion factor rather than an estimate.
How do I convert picogram per teaspoon to centigram per gallon?
Multiply the picogram per teaspoon value by 7.68e-8. The converter above does this instantly to whatever precision you set.
How do I convert centigram per gallon back to picogram per teaspoon?
Use the reverse factor: 1 centigram per gallon equals 13,020,833.33 picograms per teaspoon. You can also use the swap control in the converter above to flip the direction instantly.
What is a picogram per teaspoon?
Picogram per Teaspoon (pg/tsp) is a unit of density.
What is a centigram per gallon?
Centigram per Gallon (cg/gal) is a unit of density.
Is the picogram per teaspoon to centigram per gallon conversion exact?
Yes. Both picogram per teaspoon and centigram per gallon are defined by fixed standards rather than physical artifacts, so the factor of 7.68e-8 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.
