Unit Information

Ounce /aʊns/ Symbol: oz Unit System: Imperial

What is the Ounce?

The ounce is a unit of mass (acceptable for use as weight on Earth) and is part of the imperial system of units. It has the symbol oz.

Not to be confused with a fluid ounce (fl oz; volume) or an ounce-force (force), the ounce is the smallest of the 3 denominations of weight used in the imperial system. There are 16 ounces in a pound and 14 pounds in a stone.

The strict name for this unit is the avoirdupois ounce and in SI / metric terms it is equivalent to approximately 28.3g.

Ounces are used to indicate the weight of fabrics in Asia, the UK and North America. For example, 16 oz denim. The number refers to weight of the fabric in ounces.

The ounce was no longer seen as a legal unit of measure after the year 2000 in the UK. However, it is still used informally and is also used as the measure for portion sizes in restaurants in the UK.

Milligram /ˈmɪlɪɡram/ Symbol: mg Unit System: SI

What is the Milligram?

The milligram is a unit of mass (acceptable for use as weight on Earth) and is a submultiple of an SI base unit with the symbol mg.

1 milligram is equal to 0.001 g or 1/1000 g (one thousandth of a gram).

There exists 2 submultiples between mg and g - namely the decigram and the centigram but these are not commonly used in everyday life. The milligram is commonly used when expressing parts of a gram; especially in medicine applications.

A mosquito weighs about 2.5 mg, as does a grain of sand.
