Lot size conventions
1 standard lot = 100,000 units of base currency. 1 mini lot = 10,000. 1 micro lot = 1,000. 1 nano lot = 100. Brokers vary in which sizes they offer — this calculator converts freely between all four.
How this differs from Position Size
The Position Size Calculator recommends a lot size from your risk tolerance and stop-loss. This tool is the simpler reference conversion — 'how many units is 0.75 lots?' — useful any time you need to translate between broker quoting conventions.
Frequently Asked Questions
Why do lot conventions matter?
Position sizing, margin, and pip value all scale directly with the number of units traded — knowing the exact unit count behind a lot size keeps every other calculation accurate.
