About Converting Grams per Gallon to Grains per Teaspoon
Gram per Gallon and Grain 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
grains per teaspoon = grams per gallon × 0.0200942166054
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 grain per teaspoon equals 13.1466708828 base units, so dividing one by the other gives the direct gram per gallon-to-grain per teaspoon factor of 0.0200942166054.
Simple example
1 g/gal × 0.02009421661 = 0.0200942166 gr/tsp
1 gram per gallon = 0.0200942166 grains per teaspoon.
Real-world example
1,000 g/gal × 0.02009421661 = 20.09421661 gr/tsp
1,000 grams per gallon = 20.09421661 grains per teaspoon.

Frequently asked questions
How many grains per teaspoon are in 1 gram per gallon?
1 gram per gallon equals 0.0200942166 grains per teaspoon, using the exact defined conversion factor rather than an estimate.
How do I convert gram per gallon to grain per teaspoon?
Multiply the gram per gallon value by 0.02009421661. The converter above does this instantly to whatever precision you set.
How do I convert grain per teaspoon back to gram per gallon?
Use the reverse factor: 1 grain per teaspoon equals 49.76556288 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 grain per teaspoon?
Grain per Teaspoon (gr/tsp) is a unit of density.
Is the gram per gallon to grain per teaspoon conversion exact?
Yes. Both gram per gallon and grain per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 0.02009421661 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.
