Most commonly, units of bitcoin are expressed in decimal exponents such as BTC ("bitcoins"), mBTC ("millibitcoins"), sats (satoshis) or bit.

Unit names

Some names have been proposed for different denominations of bitcoin for everyday use. One syllable words are preferred. Capital letter symbols for multiples of Bitcoin, lower case for fractions of bitcoin, two letters for fractions of a sat. Many pay homage to the devs and other influences on the creation of Bitcoin.

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".

Table of all units

This table is intended to include all well-defined units of bitcoin value, including less common and niche units.
