About Converting Pounds per Teaspoon to Ounces per Cup
Pound 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 = pounds per teaspoon × 768
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per teaspoon equals 92026.6961794 base units, and 1 ounce per cup equals 119.826427317 base units, so dividing one by the other gives the direct pound per teaspoon-to-ounce per cup factor of 768.
Simple example
1 lb/tsp × 768 = 768 oz/cup
1 pound per teaspoon = 768 ounces per cup.
Real-world example
1,000 lb/tsp × 768 = 768,000 oz/cup
1,000 pounds per teaspoon = 768,000 ounces per cup.

What is a pound per teaspoon?
Pound per Teaspoon (lb/tsp) is a unit of density.
What is a ounce per cup?
Ounce per Cup (oz/cup) is a unit of density.
Is the pound per teaspoon to ounce per cup conversion exact?
Yes. Both pound per teaspoon and ounce per cup are defined by fixed standards rather than physical artifacts, so the factor of 768 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.
