About Converting Ounces per Teaspoon to Ounces per Cup
Ounce per Teaspoon and Ounce 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. Both are mass per volume density units.
Formula
ounces per cup = ounces per teaspoon × 48
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 ounce per cup equals 119.826427317 base units, so dividing one by the other gives the direct ounce per teaspoon-to-ounce per cup factor of 48.
Simple example
1 oz/tsp × 48 = 48 oz/cup
1 ounce per teaspoon = 48 ounces per cup.
Real-world example
1,000 oz/tsp × 48 = 48,000 oz/cup
1,000 ounces per teaspoon = 48,000 ounces per cup.

What is a ounce per teaspoon?
Ounce per Teaspoon (oz/tsp) is a unit of density.
What is a ounce per cup?
Ounce per Cup (oz/cup) is a unit of density.
Is the ounce per teaspoon to ounce per cup conversion exact?
Yes. Both ounce per teaspoon and ounce per cup are defined by fixed standards rather than physical artifacts, so the factor of 48 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.
