What Is This Tool?
This tool converts density measurements from grain per cubic foot (gr/ft^3), commonly used for airborne moisture and particulates, into ton (long) per cubic yard, a density unit typically applied to bulk materials like soil, aggregates, and minerals.

Examples
-
10 gr/ft³ converts to 0.0000172194 ton (long)/cubic yard
-
1000 gr/ft³ converts to 0.00172194 ton (long)/cubic yard
Common Use Cases
-
Calculating absolute humidity or moisture content in indoor air quality assessments
-
Reporting airborne dust concentration in occupational and industrial ventilation
-
Estimating densities of aggregates like sand and gravel for civil engineering
-
Assessing bulk densities of dredged materials, coal, or minerals for shipping
-
Specifying soil and pavement density in construction projects using imperial units
Tips & Best Practices
-
Ensure the context of density measurement matches the unit scale to avoid misinterpretation
-
Use scientific notation for very small converted values to maintain clarity
-
Verify conversion results with known reference examples to confirm accuracy
-
Remember this conversion relates very different material states—airborne vs bulk solids
Limitations
-
The units represent drastically different scales and material forms, which can affect practical interpretation
-
Converted values often become very small and may require high precision or scientific notation
-
Direct conversion may not reflect real-world density conditions without context consideration
Frequently Asked Questions
-
What does grain per cubic foot measure?
-
It measures mass density as grains of mass per cubic foot of volume, commonly used for airborne moisture or dust concentration.
-
When is ton (long) per cubic yard used?
-
It is used for quantifying mass density of bulk materials like soil, aggregates, and minerals, especially in civil engineering and construction.
-
Why might converted values be very small?
-
Because grain/cubic foot and ton (long)/cubic yard differ greatly in scale, resulting in very small numerical results after conversion.
Key Terminology
-
Grain per cubic foot [gr/ft³]
-
A unit of mass density indicating one grain of mass per one cubic foot of volume, used for measuring airborne moisture or dust.
-
Ton (long) per cubic yard
-
A mass density unit equal to one long ton divided by one cubic yard of volume, used for bulk material density in construction and shipping.
-
Mass density
-
A physical measurement of mass per unit volume, fundamental to density unit conversions.
