What is a grain in weight measurement?

A grain (gr) is a traditional unit of mass equal to exactly 64.79891 milligrams, commonly used for bullet weights, archery arrows, and historical pharmaceutical dosages.

How is the UK assay ton different from other tons?

The UK assay ton is a specialized unit used in assay practice for reporting ore and metal quantities, distinct from the long ton, short ton, and metric tonne.

In which industries is converting grain to assay ton important?

This conversion is crucial in precious metal assaying, mining exploration, metallurgy, ballistics, and when interpreting historical pharmaceutical data.

Key Features

Converts from grain, commonly used in ballistics and pharmaceutical contexts, to UK assay ton employed in mining and metallurgy assays.
Browser-based and easy-to-use interface requiring simple input and selection.
Provides clear conversion results relevant to interpreting assay reports and historical records.

Examples

500 grains converts to approximately 0.99182 Ton (assay) (UK).
1000 grains converts to approximately 1.98364 Ton (assay) (UK).

Common Use Cases

Interpreting bullet and propellant weights in ballistics studies into assay ton reporting units.
Converting arrow or broadhead weights in archery to assay ton units for specialized reporting.
Analyzing historical pharmaceutical dosages recorded in grains for reconciliation with mining assay data.
Reporting grams or ounces of precious metals per assay ton in laboratory certificates.
Calculating metal pricing and payable quantities in ore shipments based on assay results.

Tips & Best Practices

Verify the context to ensure using assay ton units distinct from long ton, short ton, or metric tonne.
Recognize that grain is a very small mass unit, so results may involve small decimal values requiring attention.
Use this conversion primarily in fields like mining, metallurgy, ballistics, or historical pharmaceutical research where traditional units persist.

Limitations

Conversion results involve very small numerical values because grain is much smaller than the assay ton.
Assay ton differs significantly from other ton units; ensure no confusion when performing calculations.
Grain usage is mostly traditional and niche; modern applications may prefer SI units for standardization.
