Calculating individual weight measurements
If you find yourself needing to convert between metric and imperial units for personal weight measurements, we have created individual converters for kilograms to stone and kilograms to pounds.
Conversions for cooking recipe units
In their cooking measurement tips section, the National Institute of Standards and Technology's Office of Weights and Measures recommends weighing dry ingredients using kitchen scales, instead of using fluid measuring cups, to ensure greater accuracy. However, you may find yourself wanting to recreate a dish from a recipe quoting dry measurements in cups.
For this reason, we've created a series of tools to help you make an approximate conversion. If you need to find out how many grams there are in a cup or how many grams there are in a milliliter, you can use our converters, utilising the list of ingredient densities sourced from the Food and Agricultural Organisation of the United Nations to make a conversion. For smaller measurements involving tablespoons, we also have a grams and tablespoons converter.

Mass / Weight Converter Definitions
With two different units of ounce and pound, you may find yourself wondering which one to reference. So, in case there's any confusion, we've outlined the differences between the different types of imperial ounce and pound below.
Ounce (Avoir)
An avoirdupois ounce is equal to 28.349523125 grams. The ounce is commonly used as a unit of mass in the United States and around the World.
Ounce (Troy)
A troy ounce (abbreviation: t oz) is equal to 31.1034768 grams. Today, the troy ounce is used only to express the mass of precious metals such as gold, platinum or silver.
Pound (Avoir)
The pound (abbreviations: lb or, sometimes in the United States, #) is a unit of mass in a number of different systems, including various systems of units of mass that formed part of English units, Imperial units, and United States customary units. Its size can vary from system to system. The most commonly used pound today is the international avoirdupois pound. We have an individual ounces and pounds conversion tool if you need it.
Pound (Troy)
Troy weight originates from the troy system of mass and dates back to before the time of William the Conqueror. The troy pound is no longer in general use. In Canada, Australia, the UK, and other places the troy pound is no longer a legal unit for trade. In the United Kingdom, the use of the troy pound was abolished on 6 January 1879. The troy pound is still used for measurements of precious metals such as gold, silver, and platinum, and sometimes gems such as opals.
To help with productivity, we now set a cookie to store the last units you have converted from and to. This means that when you re-visit this weight converter, the units will automatically be selected for you.
