How to Convert Troy Ounces to Micrograms
To convert troy ounces to micrograms, multiply the weight by the following conversion ratio: 31,103,476.8 micrograms/troy ounce.
Since one troy ounce is equal to 31,103,476.8 micrograms, you can use this simple formula to convert:
The weight in micrograms is equal to the weight in troy ounces multiplied by 31,103,476.8.
For example, here's how to convert 5 troy ounces to micrograms using the formula above.
How Many Micrograms Are in a Troy Ounce?
There are 31,103,476.8 micrograms in a troy ounce, which is why we use this value in the formula above.
Our troy ounce to microgram calculator automatically converts your weight measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Troy Ounces and micrograms are both units used to measure weight. Keep reading to learn more about each unit.
What Is a Troy Ounce?
A troy ounce is a unit of weight equal to 0.0311035 kilograms (kg), the base unit for weight. Precious metal (gold, silver, platinum) mass standard equal to 480 grains or exactly 31.1034768 grams. [1]
The troy ounce is classified as a standard unit of weight. Troy Ounces can be abbreviated as oz t; for example, 1 troy ounce can be written as 1 oz t.
When working with troy ounces (oz t) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, troy ounces (oz t) are widely used across standard weight applications within international standard workflows, engineering documentation, and technical data sheets.
What Is a Microgram?
A microgram is a unit of weight equal to 1/1,000,000,000 of a kilogram (1e-9 kg). One-millionth of a gram (10⁻⁹ kg). [2]
The microgram is classified as a metric and SI-compatible unit of weight. Micrograms can be abbreviated as µg; for example, 1 microgram can be written as 1 µg.
In the metric system, "micro" is the standard SI prefix for millionths, or 10⁻⁶. This makes the microgram (µg) a convenient decimal multiple of the gram (g).
In practice, micrograms (µg) are widely used across fine-tolerance laboratory, analytical, and micro-scale weight measurements within SI metric workflows, engineering documentation, and technical data sheets.
When converting weight between troy ounces (oz t) and micrograms (µg), keep full floating-point precision (1 oz t = 31,103,476.8 µg; 1 µg = 0.000000032 oz t) during intermediate calculations and round only the final microgram figure to match your instrument tolerance.
