The Avoirdupois Ounce vs the Troy Ounce

There are two common types of ounce used in different contexts. The avoirdupois ounce (28.349523125 g) is the everyday ounce used for food, produce, body weight, and general merchandise in countries that use imperial units. The troy ounce (31.1034768 g) is used only for precious metals such as gold, silver, and platinum.

This converter uses the avoirdupois ounce, which is the standard for almost all non-precious-metal applications. If you need to convert kilograms to troy ounces, multiply kg by 32.1507 instead.

Kilograms and Ounces in Context

The kilogram is the base unit of mass in the International System of Units (SI) and is used worldwide for science, trade, and everyday measurement. New Zealand uses the metric system, so kilograms are the standard unit here.

Ounces are part of the imperial and US customary systems, still used in the United States, United Kingdom (alongside metric), and some other countries for food labelling, body weight, and cooking. Many NZ recipes sourced from the US or UK specify weights in ounces, making this conversion useful.
