About Converting Pounds per Teaspoon to Grains per Teaspoon
Pound per Teaspoon 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 = pounds per teaspoon × 7000
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per teaspoon equals 92026.6961794 base units, and 1 grain per teaspoon equals 13.1466708828 base units, so dividing one by the other gives the direct pound per teaspoon-to-grain per teaspoon factor of 7000.
Simple example
1 lb/tsp × 7000 = 7,000 gr/tsp
1 pound per teaspoon = 7,000 grains per teaspoon.
Real-world example
1,000 lb/tsp × 7000 = 7,000,000 gr/tsp
1,000 pounds per teaspoon = 7,000,000 grains per teaspoon.

Frequently asked questions
How many grains per teaspoon are in 1 pound per teaspoon?
1 pound per teaspoon equals 7,000 grains per teaspoon, using the exact defined conversion factor rather than an estimate.
How do I convert pound per teaspoon to grain per teaspoon?
Multiply the pound per teaspoon value by 7000. The converter above does this instantly to whatever precision you set.
How do I convert grain per teaspoon back to pound per teaspoon?
Use the reverse factor: 1 grain per teaspoon equals 0.0001428571 pounds per teaspoon. You can also use the swap control in the converter above to flip the direction instantly.
What is a pound per teaspoon?
Pound per Teaspoon (lb/tsp) is a unit of density.
What is a grain per teaspoon?
Grain per Teaspoon (gr/tsp) is a unit of density.
Is the pound per teaspoon to grain per teaspoon conversion exact?
Yes. Both pound per teaspoon and grain per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 7000 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.
