What is a pennyweight (pwt)?

A pennyweight is a troy weight unit equal to 24 grains or 1/20 of a troy ounce, about 1.555 grams, traditionally used for small precious metal weights.

What is a nanogram (ng)?

A nanogram is a unit of mass equal to one billionth of a gram, used to measure extremely small masses in scientific and analytical contexts.

Why convert pennyweight to nanograms?

To enable accurate, scientific quantification of very small precious metal or gemstone masses based on traditional troy measurements.

Common Use Cases

Weighing small quantities of gold, silver, or other precious metals for trading and pricing.
Measuring component masses in jewelry design and hallmarking.
Reporting assay results that use the troy weight system.
Quantifying trace amounts in environmental or clinical assays.
Measuring tiny biological samples or nanoparticles in research.
Expressing very low-dose pharmacological or toxicological amounts.

Tips & Best Practices

Ensure units are selected correctly before conversion.
Use the tool for precise measurement needs in metallurgy and science.
Understand that nanogram precision may surpass typical jewelry requirements.
Calibrate instruments properly when handling mass values from different scales.

Limitations

Pennyweight is mainly relevant in precious metals and not widespread beyond that.
Nanogram unit precision may be excessive for general jewelry mass measurements.
Conversions require careful calibration due to differing scales of measurement.
