About Converting Grains per Cup to Kilograms per Teaspoon
Grain per Cup and Kilogram 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
kilograms per teaspoon = grains per cup × 0.00000134997729167
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 kilogram per teaspoon equals 202884.136211 base units, so dividing one by the other gives the direct grain per cup-to-kilogram per teaspoon factor of 0.00000134997729167.
Simple example
1 gr/cup × 0.000001349977292 = 0.00000135 kg/tsp
1 grain per cup = 0.00000135 kilograms per teaspoon.
Real-world example
1,000 gr/cup × 0.000001349977292 = 0.0013499773 kg/tsp
1,000 grains per cup = 0.0013499773 kilograms per teaspoon.

Frequently asked questions
How many kilograms per teaspoon are in 1 grain per cup?
1 grain per cup equals 0.00000135 kilograms per teaspoon, using the exact defined conversion factor rather than an estimate.
How do I convert grain per cup to kilogram per teaspoon?
Multiply the grain per cup value by 0.000001349977292. The converter above does this instantly to whatever precision you set.
How do I convert kilogram per teaspoon back to grain per cup?
Use the reverse factor: 1 kilogram per teaspoon equals 740,753.2009 grains per cup. You can also use the swap control in the converter above to flip the direction instantly.
What is a grain per cup?
Grain per Cup (gr/cup) is a unit of density.
What is a kilogram per teaspoon?
Kilogram per Teaspoon (kg/tsp) is a unit of density.
Is the grain per cup to kilogram per teaspoon conversion exact?
Yes. Both grain per cup and kilogram per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 0.000001349977292 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.
