Expanse has a metric system of denominations used as units of Expanse. Each denomination has its own unique name (some bear the family name of seminal figures playing a role in evolution of computer science and cryptoeconomics). The smallest denomination aka base unit of Expanse is called Wei. Below is a list of the named denominations and their value in Wei. Following a common (although somewhat ambiguous) pattern, Expanse also designates a unit (of 1e18 or one quintillion Wei) of the currency. Note that the currency is not called Expanse as many mistakenly think, nor is Expanse a unit.
