The Lamports to SOL Conversion Formula

The conversion between lamports and SOL follows a fixed, protocol-defined ratio:

1 SOL = 1,000,000,000 Lamports (10⁹)

Therefore:

• Lamports → SOL: SOL = Lamports ÷ 1,000,000,000
• SOL → Lamports: Lamports = SOL × 1,000,000,000

// Lamports to SOL
const lamportsToSol = (l) => l / 1e9;

// SOL to Lamports
const solToLamports = (s) => s * 1e9;

// 5000 lamports = ?
console.log(lamportsToSol(5000));
// Output: 0.000005

# Lamports to SOL
def lamports_to_sol(l):
    return l / 1_000_000_000

# SOL to Lamports
def sol_to_lamports(s):
    return s * 1_000_000_000

# 5000 lamports = ?
print(lamports_to_sol(5000))
# Output: 5e-06

Named after Leslie Lamport, the computer scientist whose work on distributed systems underpins Solana's architecture, a lamport is the irreducible unit of SOL — the building block of every on-chain operation.
