What is the Lot Size Converter?

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.

How to use it

  1. Enter your position in the Standard lots field (for example 0.1).
  2. Set Contract size (units/lot) to match your instrument — 100,000 for most FX pairs, but confirm it for metals, indices or crypto CFDs where it differs.
  3. Read Units (base currency) for the raw number of units the platform will actually trade.
  4. Use the Mini lots (0.1 std), Micro lots (0.01 std) and Nano lots (0.001 std) rows to see the same size expressed in each common lot convention.

How it's calculated

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.

Frequently asked

How many units is one standard lot?

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.

What is the difference between a mini, micro and nano lot?

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.

Does a smaller lot size reduce my risk?

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.
