Crypto Denomination Table — Satoshi, Gwei, Lamport & All Crypto Units
A quick-reference table of all standard units for Bitcoin (satoshi → BTC), Ethereum (wei → ETH), and Solana (lamport → SOL). Each tab shows the full denomination hierarchy with exact conversion factors. Optionally enter a live price to see USD equivalent values. Runs in your browser, no data sent anywhere.

About Crypto Denomination Reference
Cryptocurrencies are stored and transacted at the level of their smallest indivisible unit, but people talk about them in larger, friendlier units, and the gap between those scales causes constant confusion. This tool is a clean reference table that lays out the full denomination hierarchy for three major networks so you can see at a glance how the small units roll up into the headline coin. Tabs switch between Bitcoin, Ethereum, and Solana, and each tab lists every named unit alongside its exact size in both the base smallest unit and the headline asset.
The Bitcoin tab runs from the satoshi, the smallest unit at one hundred-millionth of a bitcoin, up through the microbit, millibit, centibit, and decibit to one whole BTC, which equals 100,000,000 satoshis. The Ethereum tab covers the full standard ladder, wei, kwei, mwei, gwei, szabo, and finney, up to one ether, which is 1,000,000,000,000,000,000 wei. Gwei in particular is the unit you see quoted for gas fees, and the table makes its relationship to both wei and ether explicit. The Solana tab shows the two units that matter in practice: the lamport, at one-billionth of a SOL, and SOL itself, which equals 1,000,000,000 lamports.
An optional price field turns the reference into a quick valuation aid. Enter a current price in US dollars for the selected asset and the table gains a USD column showing what each denomination is worth at that price, so you can immediately see, for example, the dollar value of a single satoshi or a gwei of gas. The price you enter is purely a multiplier you control; the tool does not fetch live market data, so the USD figures are only as accurate as the number you supply.
This is a static lookup rather than a converter for arbitrary quantities; for turning a specific amount from one unit into another there is a dedicated converter the page links to. Everything here is computed in your browser from fixed conversion factors, and nothing you type, including any price, is sent anywhere. It is handy when reading a wallet that reports balances in satoshis, when interpreting a gas estimate quoted in gwei, or when sanity-checking how many lamports make up a SOL.
Frequently Asked Questions
- What is a satoshi?
- A satoshi is the smallest unit of Bitcoin, equal to 0.00000001 BTC, or one hundred-millionth of a bitcoin. There are 100,000,000 satoshis in one BTC. It is named after Satoshi Nakamoto, the pseudonymous creator of Bitcoin, and most low-value Bitcoin amounts are reasoned about in satoshis.
- What is wei and what is gwei?
- Wei is the smallest unit of ether; one ETH equals 1,000,000,000,000,000,000 wei. Gwei, or gigawei, is one billion wei, which is 0.000000001 ETH, and it is the unit conventionally used to quote Ethereum gas prices because typical fees fall in a convenient range when expressed in gwei.
- What is a lamport?
- A lamport is the smallest unit of Solana, equal to 0.000000001 SOL, so there are 1,000,000,000 lamports in one SOL. It is named after Leslie Lamport, a foundational figure in distributed systems, and Solana fees and rent are accounted for at the lamport level.
- Why does Ethereum have so many named units?
- Ethereum defines a ladder of named denominations, wei, kwei, mwei, gwei, szabo, finney, and ether, so different contexts can use a comfortable scale. Wei gives full protocol-level precision, gwei is convenient for gas pricing, and ether is used for everyday balances. The intermediate names like szabo and finney are rarely used in practice today.
- Can I use this to convert a specific amount?
- This page is a fixed reference table showing the unit hierarchy and their relative sizes, not a free-form converter. To convert an arbitrary quantity, such as a particular number of satoshis to BTC, use the dedicated converter the page links to, which lets you type any value and see the equivalent.
- Where do the USD values come from?
- They come from the price you type into the optional price field, multiplied by each denomination's size. The tool does not connect to any market data source, so the dollar figures reflect exactly the price you supply and nothing more. Enter a current price yourself to get up-to-date values.
- Are these conversion factors exact?
- Yes. The relationships are defined by each protocol and are fixed, one BTC is exactly 100,000,000 satoshis, one ETH is exactly 1,000,000,000,000,000,000 wei, and one SOL is exactly 1,000,000,000 lamports. The table uses these exact factors.
- Is anything I enter sent to a server?
- No. The table is static and every value, including any price you type, is computed locally in your browser. Nothing is transmitted.
