The weight converter works like this: it converts mass across grams, kilograms, tonnes, ounces, pounds, stones and troy ounces for precious metals. Everything happens on your device - the input never leaves your tab unless the tool clearly states it performs a server-side lookup.

Frequently asked questions

A troy ounce is 31.103 g versus 28.349 g for a common ounce - gold and silver are always quoted in troy.
Why are troy ounces separate?
A troy ounce (31.103 g) is heavier than the everyday avoirdupois ounce (28.349 g) and is the unit precious metals are priced in - mixing them up misprices gold by nearly 10%.
What is a stone?
A British unit of 14 pounds (6.35 kg) still used for personal weight in the UK and Ireland - the tool converts stones to kilograms and back exactly.
