Troy Ounce

What is a troy ounce?

The troy ounce (ozt) equals about 31.103 grams, one-twelfth of a troy pound.

Origin of the troy ounce

From the Troy system of weights associated with Troyes, France.

Where it is used

The global standard for pricing gold, silver, platinum, and palladium.

When and where it was developed

Established in the medieval Troy system and retained for precious metals.

Worked examples

Example 1 — Convert 1 mP to oz t:
1 × 6.998285e-7 = 6.998285e-7 oz t

Example 2 — Convert 100 mP to oz t:
100 × 6.998285e-7 = 6.998285e-5 oz t

Real-world example — Sub-micron to millimeter

500,000 planck mass converts to a small everyday quantity in troy ounces — useful when relating optical-wavelength specifications to physical mounting hardware.

500000 mP × 6.998285e-7 = 0.3499142578 oz t

Real-world example — From wavelengths to millimeter-scale objects

A value of one million planck mass sounds vast at the atomic scale but converts to a small everyday quantity in troy ounces — useful when relating optical-wavelength specifications to physical mounting hardware.

1000000 mP × 6.998285e-7 = 0.6998285156 oz t
