About Converting Grains per Milliliter to Drams per Pint
Grain per Milliliter and Dram 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
drams per pint = grains per milliliter × 17.304739584
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per milliliter equals 64.79891 base units, and 1 dram per pint equals 3.74457585365 base units, so dividing one by the other gives the direct grain per milliliter-to-dram per pint factor of 17.304739584.
Simple example
1 gr/mL × 17.30473958 = 17.30473958 dr/pt
1 grain per milliliter = 17.30473958 drams per pint.
Real-world example
1,000 gr/mL × 17.30473958 = 17,304.73958 dr/pt
1,000 grains per milliliter = 17,304.73958 drams per pint.

Frequently asked questions
How many drams per pint are in 1 grain per milliliter?
1 grain per milliliter equals 17.30473958 drams per pint, using the exact defined conversion factor rather than an estimate.
How do I convert grain per milliliter to dram per pint?
Multiply the grain per milliliter value by 17.30473958. The converter above does this instantly to whatever precision you set.
How do I convert dram per pint back to grain per milliliter?
Use the reverse factor: 1 dram per pint equals 0.0577876365 grains per milliliter. You can also use the swap control in the converter above to flip the direction instantly.
What is a grain per milliliter?
Grain per Milliliter (gr/mL) is a unit of density.
What is a dram per pint?
Dram per Pint (dr/pt) is a unit of density.
Is the grain per milliliter to dram per pint conversion exact?
Yes. Both grain per milliliter and dram per pint are defined by fixed standards rather than physical artifacts, so the factor of 17.30473958 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.
