1 XLM = 10,000,000 stroops, and 1 stroops = 0.0000001 XLM. Convert any amount with the live converter above, or see the stroops to xlm or xlm to stroops tables.
Stellar's ledger runs out of decimals at the stroop: the smallest unit of the lumen, native currency of the Stellar network. Slicing one XLM yields 10,000,000 stroops, and each stroop is worth 0.0000001 lumens. Since nothing smaller exists, every Stellar amount is, in the end, a whole count of stroops.
The place most people meet stroops is in transaction fees. Stellar quotes its minimum per-operation base fee in stroops, so the cost of submitting a transaction is counted in this unit rather than in fractions of a lumen. Working in the smallest unit avoids rounding ambiguity: a fee expressed in stroops is always an exact whole number.
Stellar launched in 2014, founded by Jed McCaleb, who had previously co-founded XRP. The stroop is Stellar's answer to the XRP drop: each network gives its smallest denomination a short name of its own instead of forcing people to write long decimal fractions. Naming the base unit makes fees and tiny balances easier to talk about precisely.
Counting decimal places by eye is the slow, fallible way; the converter applies the exact ratio of 10,000,000 stroops per XLM instead. Enter lumens or stroops and the other side appears at full precision — no slipped places, no guesswork.
