Frequently asked questions
What is a lamport?
A lamport is the smallest unit of SOL on the Solana blockchain. 1 SOL = 1,000,000,000 lamports (10⁹). Lamports are named after Leslie Lamport, the computer scientist whose work underpins much of distributed-systems theory.
Why does Solana use lamports?
On chain, all values are stored as integers — fractional SOL doesn't exist at the protocol level. Lamports give Solana enough precision to represent rent fees, network fees, and tiny transfers without floating-point errors. Wallets and explorers convert to SOL only for display.
How accurate is this converter?
Conversion is exact for any value below ~9 quadrillion lamports (about 9 million SOL), which covers every realistic transaction. Above that you start hitting JavaScript's safe-integer limit; the converter rounds appropriately.
