About Converting Grains per Teaspoon to Milligrams per Pint
Grain per Teaspoon and Milligram per Pint 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
milligrams per pint = grains per teaspoon × 6220.69536
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per teaspoon equals 13.1466708828 base units, and 1 milligram per pint equals 0.00211337641887 base units, so dividing one by the other gives the direct grain per teaspoon-to-milligram per pint factor of 6220.69536.
Simple example
1 gr/tsp × 6220.69536 = 6,220.69536 mg/pt
1 grain per teaspoon = 6,220.69536 milligrams per pint.
Real-world example
1,000 gr/tsp × 6220.69536 = 6,220,695.36 mg/pt
1,000 grains per teaspoon = 6,220,695.36 milligrams per pint.

Frequently asked questions
How many milligrams per pint are in 1 grain per teaspoon?
1 grain per teaspoon equals 6,220.69536 milligrams per pint, using the exact defined conversion factor rather than an estimate.
How do I convert grain per teaspoon to milligram per pint?
Multiply the grain per teaspoon value by 6220.69536. The converter above does this instantly to whatever precision you set.
How do I convert milligram per pint back to grain per teaspoon?
Use the reverse factor: 1 milligram per pint equals 0.0001607537 grains per teaspoon. You can also use the swap control in the converter above to flip the direction instantly.
What is a grain per teaspoon?
Grain per Teaspoon (gr/tsp) is a unit of density.
What is a milligram per pint?
Milligram per Pint (mg/pt) is a unit of density.
Is the grain per teaspoon to milligram per pint conversion exact?
Yes. Both grain per teaspoon and milligram per pint are defined by fixed standards rather than physical artifacts, so the factor of 6220.69536 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.
