 Weight

The standard method for specifying the weight is to use |weight={{convert|x.xx|carat|g}}. To have the weight automatically converted, use |carats=x.xx or |grams=x.xx. If both carats and grams are specified, the template will ignore the measurement in grams, and convert the weight from the value specified in carats.
