About Converting Drams per Cubic Millimeter to Grains per Teaspoon
Dram per Cubic Millimeter 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 = drams per cubic millimeter × 134775.199829
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per cubic millimeter equals 1771845.19531 base units, and 1 grain per teaspoon equals 13.1466708828 base units, so dividing one by the other gives the direct dram per cubic millimeter-to-grain per teaspoon factor of 134775.199829.
Simple example
1 dr/mm3 × 134775.1998 = 134,775.1998 gr/tsp
1 dram per cubic millimeter = 134,775.1998 grains per teaspoon.
Real-world example
1,000 dr/mm3 × 134775.1998 = 134,775,199.8 gr/tsp
1,000 drams per cubic millimeter = 134,775,199.8 grains per teaspoon.

Frequently asked questions
How many grains per teaspoon are in 1 dram per cubic millimeter?
1 dram per cubic millimeter equals 134,775.1998 grains per teaspoon, using the exact defined conversion factor rather than an estimate.
How do I convert dram per cubic millimeter to grain per teaspoon?
Multiply the dram per cubic millimeter value by 134775.1998. The converter above does this instantly to whatever precision you set.
How do I convert grain per teaspoon back to dram per cubic millimeter?
Use the reverse factor: 1 grain per teaspoon equals 0.0000074198 drams per cubic millimeter. You can also use the swap control in the converter above to flip the direction instantly.
What is a dram per cubic millimeter?
Dram per Cubic Millimeter (dr/mm3) is a unit of density.
What is a grain per teaspoon?
Grain per Teaspoon (gr/tsp) is a unit of density.
Is the dram per cubic millimeter to grain per teaspoon conversion exact?
Yes. Both dram per cubic millimeter and grain per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 134775.1998 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.
