## Unit Information

Pound
/paʊnd/
Symbol: lb
Unit System: Imperial

### What is the Pound?

The pound 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 lb.

Not to be confused with a number of other definitions, the most common is international avoirdupois pound. The avoirdupois pound is defined as exactly 0.45359237 kilograms and is divided into 16 avoirdupois ounces.

One of the most common uses of the pound is in measuring the mass / weight of human beings or animals. When introduced, sports athletes such as boxers or wrestlers are described by their weight in pounds before any other characteristic as it helps people visualise how big / powerful they are.

The unit pounds originated from the Roman ‘libra’ (hence the abbreviated ‘lb’). The libra, which is Latin for scales or balance, was an ancient Roman unit used to measure mass and was equivalent to approximately 328.9 grams. The libra was originally split into 12 ounces (or unciae).

Random fact: Some cannons, such as the Smoothbore cannon, are based on the imperial pounds of circular solid iron balls of the diameters that fit the barrels. For example, a cannon that fires 12-pound ball is called a twelve-pounder.

Microgram
/ˈmʌɪkrə(ʊ)ɡram/
Symbol: µg
Unit System: SI

### What is the Microgram?

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

1 microgram is equal to 0.000001 or 1/1000000 g (one millionth of a gram).

The symbol μg is avoided in medical practises / applications because there is a chance the 'μ' could be misread as an 'm'; resulting in mg being interpreted rather than μg - which could lead to a 1000x overdose.
