Units
Most commonly, units of bitcoin are expressed in decimal exponents such as BTC ("bitcoins"), mBTC ("millibitcoins") and μBTC ("bits").
Decimal metric units
The BTC unit was chosen to represent a value of 108 so as to give sub-unit precision rather than large whole numbers. Mirroring the standard Le Système International d'Unités, this allows for divisions of 1/10th (deci-bitcoins, dBTC), 1/100th (centi-bitcoins, cBTC), 1/1 000th (milli-bitcoins, mBTC), and 1/1 000 000 (micro-bitcoins, μBTC).
Bits
Many have adopted the practice of referring to the micro-bitcoin metric sub-unit as "bits".
