About Converting Ounces per Cup to Pounds per Teaspoon
Ounce per Cup and Pound 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
pounds per teaspoon = ounces per cup × 0.00130208333333
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per cup equals 119.826427317 base units, and 1 pound per teaspoon equals 92026.6961794 base units, so dividing one by the other gives the direct ounce per cup-to-pound per teaspoon factor of 0.00130208333333.
Simple example
1 oz/cup × 0.001302083333 = 0.0013020833 lb/tsp
1 ounce per cup = 0.0013020833 pounds per teaspoon.
Real-world example
1,000 oz/cup × 0.001302083333 = 1.302083333 lb/tsp
1,000 ounces per cup = 1.302083333 pounds per teaspoon.
