Cryptocurrency enthusiasts often dive deep into price charts, market caps, and blockchain technology — but one fundamental concept that’s sometimes overlooked is the smallest unit of a digital asset. Just like how a dollar can be divided into cents, most cryptocurrencies are divisible into far smaller denominations. Understanding these micro-units isn’t just technical trivia — it plays a crucial role in usability, transaction precision, and even cultural recognition within the crypto community.
In this article, we’ll explore the tiniest measurable units of four major cryptocurrencies: Bitcoin (BTC), Ethereum (ETH), EOS, and Litecoin (LTC). We’ll uncover their names, origins, conversion rates, and the fascinating stories behind them — including how one founder’s surname became a unit of value.
Bitcoin (BTC): The Satoshi (SAT)
👉 Discover how the smallest unit of Bitcoin is revolutionizing microtransactions today.
The smallest unit of Bitcoin is called the Satoshi, or SAT for short. Named after Bitcoin’s mysterious creator Satoshi Nakamoto, one Bitcoin equals 100 million Satoshis (1 BTC = 100,000,000 SAT). This high level of divisibility ensures Bitcoin can be used for both large investments and tiny everyday payments — even if BTC reaches six figures in value.
While many newcomers are intimidated by Bitcoin’s high price tag, knowing that they can buy or transact in Satoshis makes it far more accessible. For instance, instead of purchasing a full BTC, users can start with just a few thousand Satoshis.
Other Bitcoin Units
Although Satoshi is the smallest recognized unit, Bitcoin has several intermediate denominations:
- Bitcent (cBTC): 1% of a Bitcoin
- Milli-Bitcoin (mBTC): 1/1,000th of a Bitcoin
- Micro-Bitcoin (μBTC): 1/1,000,000th of a Bitcoin
Despite these alternatives, Satoshi remains the most widely used subunit, especially in wallets, exchanges, and peer-to-peer transactions.
There’s even an ongoing debate in the crypto space about whether Bitcoin should transition from BTC to SAT as the default display unit. Proponents argue that using Satoshis would make pricing more intuitive and scalable for future adoption — imagine paying 50 million SAT for a car instead of 0.5 BTC.
Ethereum (ETH): The Wei and Scientific Legacy
Ethereum takes a unique approach by naming its smallest units after pioneers in computer science and cryptography. The base unit of ETH is called Wei, in honor of Wei Dai, a Chinese-American cryptographer who proposed B-Money in 1998 — a direct conceptual predecessor to Bitcoin.
Satoshi Nakamoto cited Dai’s work in the original Bitcoin whitepaper, making the tribute both meaningful and historically significant.
Ethereum Unit Hierarchy
One Ether equals 1 quintillion Wei (1 ETH = 10¹⁸ Wei). Here's how the rest break down:
- 1 Gwei (Shannon) = 1 billion Wei (10⁹)
- 1 Szabo = 1 million Wei (10¹²)
- 1 Finney = 1 thousand Ether (10¹⁵)
- Larger units like Kwei (Babbage) and Mwei (Lovelace) also pay homage to computing legends such as Charles Babbage and Ada Lovelace.
Gwei is particularly important in daily Ethereum usage — it’s commonly used to denote gas prices when sending transactions or interacting with smart contracts. When your wallet shows “25 Gwei,” you’re seeing the cost per unit of computational effort on the network.

This naming convention reflects Ethereum’s ethos: blending technological innovation with intellectual heritage.
EOS: The Larimer
EOS stands out with a bold naming choice — its smallest unit is called the Larimer. One EOS equals 10,000 Larimers, making it less granular than Bitcoin or Ethereum but still functional for standard transactions.
The name honors Daniel Larimer, better known by his online alias BM (Byte Master), the co-founder and original architect of EOS. While some find this self-referential naming unusual, it underscores Larimer’s influential role in shaping EOS and earlier blockchains like BitShares and Steem.
Unlike Bitcoin and Ethereum, which use neutral or academically inspired terminology, EOS embraces a more personal legacy — turning its creator’s surname into a permanent part of its economic structure.
While not universally adopted across wallets and exchanges, the term "Larimer" appears in technical documentation and developer discussions, preserving this quirky tribute within the ecosystem.
Litecoin (LTC): The Litoshi
Litecoin, often referred to as the "silver to Bitcoin’s gold," mirrors many aspects of Bitcoin’s design — including its divisibility. The smallest unit of Litecoin is called the Litoshi, a clear nod to both Satoshi Nakamoto and Litecoin’s own identity.
Just like Bitcoin:
- 1 LTC = 100 million Litoshi
This symmetry simplifies user experience for those transitioning between BTC and LTC. Wallets, exchanges, and payment processors treat both currencies similarly in terms of precision and formatting.
Given that Litecoin was created by former Google engineer Charlie Lee to improve transaction speed and accessibility, having a highly divisible unit supports its vision of being a practical medium for everyday payments.
Even at lower market values compared to Bitcoin, the existence of Litoshi allows for microtransactions, tipping, and fractional investing — all essential features for long-term utility.
Frequently Asked Questions (FAQ)
Q: Why do cryptocurrencies need such small units?
A: High divisibility allows for precise transactions, supports micro-payments (e.g., paying for digital content by the second), and ensures usability even if the coin's value increases dramatically over time.
Q: Can I send less than 1 Bitcoin?
A: Yes! You can send any amount down to 1 Satoshi (0.00000001 BTC). Most wallets support sending fractions of BTC using Satoshis behind the scenes.
Q: Is Wei used in everyday Ethereum transactions?
A: While users typically see ETH amounts in decimal form (e.g., 0.05 ETH), Gwei — a larger subunit of Wei — is used to set gas prices during transactions. So yes, Wei-based units are actively used every day.
Q: Why isn’t Larimer more widely recognized?
A: Unlike Satoshi or Wei, which have broader community and technical adoption, “Larimer” is mostly used internally within EOS documentation. External platforms often stick to decimal representations (e.g., 0.0001 EOS).
Q: Is Litoshi an official term?
A: While not always displayed in user interfaces, Litoshi is recognized in Litecoin’s technical framework and commonly used among developers and enthusiasts.
Q: Could Satoshis become the standard way to quote Bitcoin prices?
A: Many experts believe so. As Bitcoin becomes more valuable, quoting prices in Satoshis could make transactions more intuitive — similar to how we use cents instead of dollars for small purchases.
Final Thoughts
Understanding the smallest units of cryptocurrencies goes beyond technical detail — it reveals cultural values, historical influences, and forward-thinking design choices. From honoring pioneers like Wei Dai to immortalizing creators like Daniel Larimer, these micro-denominations reflect the human stories behind decentralized technologies.
Whether you're investing in BTC by the Satoshi, setting gas fees in Gwei, or exploring EOS through Larimers, knowing these units empowers smarter participation in the digital economy.
