About Converting Grams per Teaspoon to Grams per Cup
Gram per Teaspoon and Gram 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
grams per cup = grams per teaspoon × 48
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per teaspoon equals 202.884136211 base units, and 1 gram per cup equals 4.22675283773 base units, so dividing one by the other gives the direct gram per teaspoon-to-gram per cup factor of 48.
Simple example
1 g/tsp × 48 = 48 g/cup
1 gram per teaspoon = 48 grams per cup.
Real-world example
1,000 g/tsp × 48 = 48,000 g/cup
1,000 grams per teaspoon = 48,000 grams per cup.

Frequently asked questions
How many grams per cup are in 1 gram per teaspoon?
1 gram per teaspoon equals 48 grams per cup, using the exact defined conversion factor rather than an estimate.
How do I convert gram per teaspoon to gram per cup?
Multiply the gram per teaspoon value by 48. The converter above does this instantly to whatever precision you set.
How do I convert gram per cup back to gram per teaspoon?
Use the reverse factor: 1 gram per cup equals 0.0208333333 grams per teaspoon. You can also use the swap control in the converter above to flip the direction instantly.
What is a gram per teaspoon?
Gram per Teaspoon (g/tsp) is a unit of density.
What is a gram per cup?
Gram per Cup (g/cup) is a unit of density.
Is the gram per teaspoon to gram per cup conversion exact?
Yes. Both gram per teaspoon and gram 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.
