Unknown Abbreviations

I'm trying to identify the abbreviations 'dwt' and 'ozt', both of which appear as weight modes on a scale, along with 'gr' and 'oz'.  Any ideas/suggestions?  Thanks!

The symbol dwt stands for the pennyweight, which is equal to 1/20[sup]th[/sup] of a troy ounce.

The symbol ozt stands for the troy ounce which is 1/12[sup]th[/sup] of a troy pound.

The troy ounce is 192/175[sup]th[/sup] of a standard avoirdupois ounce.

The symbol gr stands for the grain, which is 1/480[sup]th[/sup] of a troy ounce.

The symbol oz stands for the avoirdupois ounce. The common ounce used today in the U.S. It is 175/192[sup]nd[/sup] of a troy ounce.

I am working on a glossary of terms and symbols, but because of the large number units there are it will take me awhile to have the glossary completed enough to be useful.
