What is a Pound and a Microgram?

The pound (avoirdupois) is a unit of mass used in the imperial and US customary systems. It is defined as exactly 0.45359237 kilograms.

A microgram is a unit of mass in the metric system equal to one millionth (1/1,000,000) of a gram, or one thousandth (1/1,000) of a milligram. It is often denoted by the symbol µg.

Note: The Pound is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Microgram belongs to the metric (SI) system.

History of the Pound and Microgram

Originates from the Roman 'libra'. The avoirdupois pound became the standard for commerce in England and was later adopted in the US.

The microgram is derived from the gram, a base unit in early metric systems defined in the late 18th century. The prefix "micro-" indicates a factor of 10⁻⁶.
