Each Bitcoin is equal to 100 million satoshi, or "sats", making a satoshi the smallest unit of bitcoin recorded on the blockchain. A satoshi is the smallest unit of bitcoin, like cents to the US Dollar. However, one satoshi is 0.00000001 bitcoin, making a satoshi relatively much smaller.
Smaller denominations make bitcoin easier to trade in smaller amounts. Payments of a few hundred satoshi are jokingly referred to as "crypto dust" in the metaverse, but having this level of granularity is important at scale.
Satoshi is the namesake chosen by the creator of Bitcoin, Satoshi Nakamoto, author of the Bitcoin White Paper. Below you will find a quick conversion table to visualize the satoshi next to a full bitcoin.
