The Lot Size Converter is a unit-conversion tool for forex position sizes. It answers one question directly: given a number of standard lots and your instrument's contract size, exactly how many base-currency units — and how many mini, micro and nano lots — does that represent? It is a deterministic conversion, not a sizing recommendation.
Units = standard lots × contract size. From there each lot tier is a fixed fraction of a standard lot: mini lots = standard lots ÷ 0.1, micro lots = standard lots ÷ 0.01, and nano lots = standard lots ÷ 0.001. So 0.1 standard lots at a 100,000-unit contract equals 10,000 units, which is 1 mini lot, 10 micro lots and 100 nano lots.
For most currency pairs a standard lot is 100,000 units of the base currency, which is why this lot size converter uses 100,000 as the default contract size. Always check the contract size for non-FX instruments, as it can differ.
A mini lot is 0.1 of a standard lot (10,000 units), a micro lot is 0.01 (1,000 units) and a nano lot is 0.001 (100 units). Each step down divides your position size by ten.
A smaller lot reduces the units traded and therefore the money per pip, but your actual risk still depends on your stop distance and account size — this converter only translates the units, it does not set risk.
Keep in mind: This is a pure units conversion — it tells you how big a position is, not whether that size is appropriate for your account or stop distance. Confirm the contract size for your specific instrument, since a wrong contract size makes every converted figure wrong.
