About Converting Ounces per Teaspoon to Carats per Milliliter
Ounce per Teaspoon and Carat 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
carats per milliliter = ounces per teaspoon × 28.7583425561
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per teaspoon equals 5751.66851121 base units, and 1 carat per milliliter equals 200 base units, so dividing one by the other gives the direct ounce per teaspoon-to-carat per milliliter factor of 28.7583425561.
Simple example
1 oz/tsp × 28.75834256 = 28.75834256 ct/mL
1 ounce per teaspoon = 28.75834256 carats per milliliter.
Real-world example
1,000 oz/tsp × 28.75834256 = 28,758.34256 ct/mL
1,000 ounces per teaspoon = 28,758.34256 carats per milliliter.

Frequently asked questions
How many carats per milliliter are in 1 ounce per teaspoon?
1 ounce per teaspoon equals 28.75834256 carats per milliliter, using the exact defined conversion factor rather than an estimate.
How do I convert ounce per teaspoon to carat per milliliter?
Multiply the ounce per teaspoon value by 28.75834256. The converter above does this instantly to whatever precision you set.
How do I convert carat per milliliter back to ounce per teaspoon?
Use the reverse factor: 1 carat per milliliter equals 0.0347725186 ounces per teaspoon. You can also use the swap control in the converter above to flip the direction instantly.
What is a ounce per teaspoon?
Ounce per Teaspoon (oz/tsp) is a unit of density.
What is a carat per milliliter?
Carat per Milliliter (ct/mL) is a unit of density.
Is the ounce per teaspoon to carat per milliliter conversion exact?
Yes. Both ounce per teaspoon and carat per milliliter are defined by fixed standards rather than physical artifacts, so the factor of 28.75834256 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.
