About Converting Grams per Milliliter to Drams per Cup
Gram per Milliliter and Dram per Cup 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. Gram per Milliliter is most often used for commonly used in chemistry coursework and laboratory reporting to express the density of liquids and solutions.
Formula
drams per cup = grams per milliliter × 133.526471232
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per milliliter equals 1000 base units, and 1 dram per cup equals 7.48915170731 base units, so dividing one by the other gives the direct gram per milliliter-to-dram per cup factor of 133.526471232.
Simple example
1 g/mL × 133.5264712 = 133.5264712 dr/cup
1 gram per milliliter = 133.5264712 drams per cup.
Real-world example
1,000 g/mL × 133.5264712 = 133,526.4712 dr/cup
1,000 grams per milliliter = 133,526.4712 drams per cup.

Frequently asked questions
How many drams per cup are in 1 gram per milliliter?
1 gram per milliliter equals 133.5264712 drams per cup, using the exact defined conversion factor rather than an estimate.
How do I convert gram per milliliter to dram per cup?
Multiply the gram per milliliter value by 133.5264712. The converter above does this instantly to whatever precision you set.
How do I convert dram per cup back to gram per milliliter?
Use the reverse factor: 1 dram per cup equals 0.0074891517 grams per milliliter. You can also use the swap control in the converter above to flip the direction instantly.
What is a gram per milliliter?
Gram per Milliliter (g/mL) measures density. Numerically identical to grams per cubic centimeter and to kilograms per liter, since one milliliter equals one cubic centimeter exactly. It is classified as a metric derived density unit.
What is a dram per cup?
Dram per Cup (dr/cup) is a unit of density.
Is the gram per milliliter to dram per cup conversion exact?
Yes. Numerically identical to grams per cubic centimeter and to kilograms per liter, since one milliliter equals one cubic centimeter exactly. That fixed definition is what the converter above uses, so any rounding you see is a display choice, not a limitation of the math.
Where is the gram per milliliter still used today?
Widely used in chemistry education and laboratory settings internationally
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.
