Polkadot Units: DOT and Planck
Polkadot records every amount in Planck, where 1 DOT = 10,000,000,000 Planck(10 decimal places). Planck keeps on-chain accounting exact using integers, and you will meet it when reading raw chain state, building with the Polkadot.js API, or calculating staking rewards.
- 1 Planck = 0.0000000001 DOT (the smallest possible amount)
- 1 DOT = 10,000,000,000 Planck (10^10)
- Polkadot.js represents balances in Planck as BigInt values
Frequently Asked Questions
How many Planck are in 1 DOT?
1 DOT = 10,000,000,000 Planck (10^10). Polkadot uses 10 decimal places, so one Planck is the smallest indivisible unit, equal to 0.0000000001 DOT.
What is a Planck in Polkadot?
The Planck is the smallest unit of DOT, named after physicist Max Planck. All on-chain balances, fees, and staking amounts are stored in Planck as integers; user interfaces convert them to DOT for display.
How do I convert DOT to Planck?
Multiply the DOT amount by 10,000,000,000 (10^10). For example, 1.5 DOT = 15,000,000,000 Planck. To reverse it, divide the Planck value by 10^10.
Why does Polkadot use 10 decimals?
Polkadot chose 10 decimal places (after the 2020 redenomination) to balance precision with readable numbers. Storing amounts as integer Planck avoids floating-point rounding errors on-chain.
