Solana Lamports to SOL Conversion — Quick Reference

RPC and Solscan show lamports; wallets show SOL. Misreading units causes wrong fee and rent estimates.

Lamports ↔ SOL converter

1 SOL = 1,000,000,000 lamports exactly. SPL token raw amounts use mint decimals — not lamports.

Key facts

  • Use the converter below for exact lamports ↔ SOL.
  • Example: 2,500,000,000 lamports = 2.5 SOL.
  • Example: 75,000,000 lamports = 0.075 SOL (matches revoke mint platform fee in current pricing).

What this means

Quick math: lamports ÷ 1e9 = SOL; SOL × 1e9 = lamports. Base tx fee ≈ 5,000 lamports (0.000005 SOL) per Solana docs — priority fees add more under congestion. SPL token amounts use each mint's decimals field — do not divide token raw amounts by 1e9 unless the mint uses 9 decimals. Token account rent-exempt minimum is a separate lamport balance (~0.002 SOL depending on account size). MMAC platform fees are quoted in SOL on /pricing but settle on-chain in lamports when you sign.

Step-by-step

  1. Use the converter below for exact lamports ↔ SOL.
  2. Example: 2,500,000,000 lamports = 2.5 SOL.
  3. Example: 75,000,000 lamports = 0.075 SOL (matches revoke mint platform fee in current pricing).
  4. In @solana/web3.js use LAMPORTS_PER_SOL instead of hardcoding 1e9.
  5. On Solscan tx pages, cross-check lamport and SOL columns match.
