About Converting Troy ounce per Cubic inches to Grains per Cubic Meter
Troy ounce per Cubic inch and Grain per Cubic Meter 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
grains per cubic meter = troy ounce per cubic inches × 29291397.1655
This factor comes from each unit's defined relationship to the category's base unit: 1 troy ounce per cubic inch equals 1898.0506087 base units, and 1 grain per cubic meter equals 0.00006479891 base units, so dividing one by the other gives the direct troy ounce per cubic inch-to-grain per cubic meter factor of 29291397.1655.
Simple example
1 oz t/in3 × 29291397.17 = 29,291,397.17 gr/m3
1 troy ounce per cubic inch = 29,291,397.17 grains per cubic meter.
Real-world example
1,000 oz t/in3 × 29291397.17 = 29,291,397,170 gr/m3
1,000 troy ounce per cubic inches = 29,291,397,170 grains per cubic meter.

Frequently asked questions
How many grains per cubic meter are in 1 troy ounce per cubic inch?
1 troy ounce per cubic inch equals 29,291,397.17 grains per cubic meter, using the exact defined conversion factor rather than an estimate.
How do I convert troy ounce per cubic inch to grain per cubic meter?
Multiply the troy ounce per cubic inch value by 29291397.17. The converter above does this instantly to whatever precision you set.
How do I convert grain per cubic meter back to troy ounce per cubic inch?
Use the reverse factor: 1 grain per cubic meter equals 3.413972e-8 troy ounce per cubic inches. You can also use the swap control in the converter above to flip the direction instantly.
What is a troy ounce per cubic inch?
Troy ounce per Cubic inch (oz t/in3) is a unit of density.
What is a grain per cubic meter?
Grain per Cubic Meter (gr/m3) is a unit of density.
Is the troy ounce per cubic inch to grain per cubic meter conversion exact?
Yes. Both troy ounce per cubic inch and grain per cubic meter are defined by fixed standards rather than physical artifacts, so the factor of 29291397.17 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.
