About Converting Ounces per Tablespoon to Ounces per Teaspoon
Ounce per Tablespoon and Ounce 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
ounces per teaspoon = ounces per tablespoon × 0.333333333333
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per tablespoon equals 1917.22283707 base units, and 1 ounce per teaspoon equals 5751.66851121 base units, so dividing one by the other gives the direct ounce per tablespoon-to-ounce per teaspoon factor of 0.333333333333.
Simple example
1 oz/tbsp × 0.3333333333 = 0.3333333333 oz/tsp
1 ounce per tablespoon = 0.3333333333 ounces per teaspoon.
Real-world example
1,000 oz/tbsp × 0.3333333333 = 333.3333333 oz/tsp
1,000 ounces per tablespoon = 333.3333333 ounces per teaspoon.

What is a ounce per teaspoon?
Ounce per Teaspoon (oz/tsp) is a unit of density.
Is the ounce per tablespoon to ounce per teaspoon conversion exact?
Yes. Both ounce per tablespoon and ounce per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 0.3333333333 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.
