About Converting Grams per Tablespoon to Grams per Cup
Gram per Tablespoon 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 tablespoon × 16
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per tablespoon equals 67.6280454037 base units, and 1 gram per cup equals 4.22675283773 base units, so dividing one by the other gives the direct gram per tablespoon-to-gram per cup factor of 16.
Simple example
1 g/tbsp × 16 = 16 g/cup
1 gram per tablespoon = 16 grams per cup.
Real-world example
1,000 g/tbsp × 16 = 16,000 g/cup
1,000 grams per tablespoon = 16,000 grams per cup.

Frequently asked questions
How many grams per cup are in 1 gram per tablespoon?
1 gram per tablespoon equals 16 grams per cup, using the exact defined conversion factor rather than an estimate.
How do I convert gram per tablespoon to gram per cup?
Multiply the gram per tablespoon value by 16. The converter above does this instantly to whatever precision you set.
How do I convert gram per cup back to gram per tablespoon?
Use the reverse factor: 1 gram per cup equals 0.0625 grams per tablespoon. You can also use the swap control in the converter above to flip the direction instantly.
What is a gram per tablespoon?
Gram per Tablespoon (g/tbsp) 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 tablespoon to gram per cup conversion exact?
Yes. Both gram per tablespoon and gram per cup are defined by fixed standards rather than physical artifacts, so the factor of 16 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.
