The conversion formula for ounces (oz) to grams (g) conversions is as follows:
The gram was the original base weight unit of the metric system being defined in 1795 as "the absolute weight of a volume of water equal to the cube of the hundredth part of the metre, at the temperature of melting ice" or the weight of a cubic centimetre of water at 0 degrees celsius in simpler parlance.
The gram is now defined as being a one thousandth part of a kilogram.
The gram was originally the base weight unit of the metric system but this changed as for most commercial use the gram was too small a unit.
Using alternate abbreviations for the gram such a gm could lead to confusion and as such is not recommended.
The gram was the original base unit of weight in the French metric system and was originally defined in 1795 as "the absolute weight of a volume of water equal to the cube of the hundredth part of the metre, at the temperature of melting ice".
The gram was considered too small to be the base unit and use of the kilogram was much more common in commercial and scientific applications and thus in 1799 a prototype kilogram was created out of platinum that then became the base unit.
In daily use, in many countries, the gram can be seen as a measurement on food labels and some higher value loose produce is sold at a price per 100 grams.
Grams are recognised world wide although they are not often used outside of scientific applications in the United States.
The ounce is one sixteenth of a pound in the avoirdupois weight system and is common to both the US Customary and British Imperial systems.
Originally derived from a roman weight unit, the ounce is commonly found in recipes in the US, UK and many British Commonwealth countries.
Avoirdupois - British Imperial & US Customary
The ounce is defined as 1/16th of a pound.
The ounce is used in both the US Customary and British Imperial weight systems and has been in use since before the time of Elizabeth I (1533-1603). In 1588 Elizabeth I approved a statute that fixed the avoirdupois pound at 7,000 grains which is the current size - this change was the last major change in definition affecting the ounce.
The ounce was one of the main units used in recipes and is still in common use in the UK by cooks, despite the metric system being adopted in 1970 and the ounce ceasing to be a legal unit of measure (for economic, health, safety or administration) in the year 2000. Interestingly the health/safety aspect of this legislation should prevent the ounce being used in commercial kitchens as a measure for ingredients.
The ounce is in statutory use in the United States and is informally used in the United Kingdom and British Commonwealth countries, such as Australia, Cannada, Jamaica, New Zealand and South Africa.
