About Converting Grains per Cup to Centigrams per Teaspoon
Grain per Cup and Centigram 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
centigrams per teaspoon = grains per cup × 0.134997729167
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per cup equals 0.273888976724 base units, and 1 centigram per teaspoon equals 2.02884136211 base units, so dividing one by the other gives the direct grain per cup-to-centigram per teaspoon factor of 0.134997729167.
Simple example
1 gr/cup × 0.1349977292 = 0.1349977292 cg/tsp
1 grain per cup = 0.1349977292 centigrams per teaspoon.
Real-world example
1,000 gr/cup × 0.1349977292 = 134.9977292 cg/tsp
1,000 grains per cup = 134.9977292 centigrams per teaspoon.

Frequently asked questions
How many centigrams per teaspoon are in 1 grain per cup?
1 grain per cup equals 0.1349977292 centigrams per teaspoon, using the exact defined conversion factor rather than an estimate.
How do I convert grain per cup to centigram per teaspoon?
Multiply the grain per cup value by 0.1349977292. The converter above does this instantly to whatever precision you set.
How do I convert centigram per teaspoon back to grain per cup?

What is a grain per cup?
Grain per Cup (gr/cup) is a unit of density.
What is a centigram per teaspoon?
Centigram per Teaspoon (cg/tsp) is a unit of density.
Is the grain per cup to centigram per teaspoon conversion exact?
Yes. Both grain per cup and centigram per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 0.1349977292 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.
