The word 'ton' names three different weights: the metric tonne (1,000 kg), the US short ton (about 907 kg) and the UK long ton (about 1,016 kg). US sources almost always mean the short ton, older UK sources the long ton. Check which ton is meant before converting, they differ by up to 11%.
The everyday avoirdupois ounce is about 28.35 g, but precious metals are priced in troy ounces of about 31.10 g. An 'ounce of gold' is nearly 10% heavier than an ounce of flour. Use troy ounces for gold and silver, the regular ounce for everything else.
