SOL ↔ Lamport Converter

Convert between SOL and Lamports

About SOL ↔ Lamport Converter

On the Solana blockchain, the native token SOL is divisible into Lamports, named after Leslie Lamport. One SOL equals exactly 1,000,000,000 (one billion) Lamports. The Solana runtime, RPC endpoints, and program instructions all operate in Lamports, so developers need to convert between the human-readable SOL denomination and the integer Lamport values that the chain actually processes.

This converter handles the 9-decimal-place conversion accurately in both directions. Enter an amount in SOL to get Lamports, or enter Lamports to see the SOL equivalent. It is particularly useful when building transactions, checking account balances via RPC, or debugging on-chain programs where all amounts appear as raw Lamport integers.

Frequently asked questions

How many Lamports are in 1 SOL?

1 SOL = 1,000,000,000 Lamports (10^9 Lamports).

Why is it called a Lamport?

Lamports are named after Leslie Lamport, a computer scientist known for his foundational work on distributed systems, which is core to Solana's design.

Do Solana programs use SOL or Lamports?

All Solana programs and the runtime use Lamports internally. SOL is only a human-readable convenience. This converter bridges the two.
