About Converting Grams per Cup to Stones per Teaspoon
Gram per Cup and Stone 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
stones per teaspoon = grams per cup × 0.00000328068842537
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per cup equals 4.22675283773 base units, and 1 stone per teaspoon equals 1288373.74651 base units, so dividing one by the other gives the direct gram per cup-to-stone per teaspoon factor of 0.00000328068842537.
Simple example
1 g/cup × 0.000003280688425 = 0.0000032807 st/tsp
1 gram per cup = 0.0000032807 stones per teaspoon.
Real-world example
1,000 g/cup × 0.000003280688425 = 0.0032806884 st/tsp
1,000 grams per cup = 0.0032806884 stones per teaspoon.

What is a gram per cup?
Gram per Cup (g/cup) is a unit of density.
What is a stone per teaspoon?
Stone per Teaspoon (st/tsp) is a unit of density.
Is the gram per cup to stone per teaspoon conversion exact?
Yes. Both gram per cup and stone per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 0.000003280688425 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.
