About Converting Drams per Teaspoon to Ounces per Milliliter
Dram per Teaspoon and Ounce per Milliliter 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
ounces per milliliter = drams per teaspoon × 0.0126802585132
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per teaspoon equals 359.479281951 base units, and 1 ounce per milliliter equals 28349.523125 base units, so dividing one by the other gives the direct dram per teaspoon-to-ounce per milliliter factor of 0.0126802585132.
Simple example
1 dr/tsp × 0.01268025851 = 0.0126802585 oz/mL
1 dram per teaspoon = 0.0126802585 ounces per milliliter.
Real-world example
1,000 dr/tsp × 0.01268025851 = 12.68025851 oz/mL
1,000 drams per teaspoon = 12.68025851 ounces per milliliter.

Frequently asked questions
How many ounces per milliliter are in 1 dram per teaspoon?
1 dram per teaspoon equals 0.0126802585 ounces per milliliter, using the exact defined conversion factor rather than an estimate.
How do I convert dram per teaspoon to ounce per milliliter?
Multiply the dram per teaspoon value by 0.01268025851. The converter above does this instantly to whatever precision you set.
How do I convert ounce per milliliter back to dram per teaspoon?
Use the reverse factor: 1 ounce per milliliter equals 78.8627455 drams per teaspoon. You can also use the swap control in the converter above to flip the direction instantly.
What is a dram per teaspoon?
Dram per Teaspoon (dr/tsp) is a unit of density.
What is a ounce per milliliter?
Ounce per Milliliter (oz/mL) is a unit of density.
Is the dram per teaspoon to ounce per milliliter conversion exact?
Yes. Both dram per teaspoon and ounce per milliliter are defined by fixed standards rather than physical artifacts, so the factor of 0.01268025851 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.
