How the Calculation Works
Forex position sizes are quoted in standard lots, mini lots, micro lots, nano lots, or raw currency units. This tool converts your input into the total number of currency units, then re-expresses that total in every other unit.
Formula
1 Standard Lot = 100,000 units
1 Mini Lot = 10,000 units
1 Micro Lot = 1,000 units
1 Nano Lot = 100 units
Example Calculation
2.5 mini lots = 25,000 units = 0.25 standard lots = 25 micro lots = 250 nano lots.
Frequently Asked Questions

Forex Lot Size Converter: Standard, Mini, Micro, and Nano Made Simple
New traders searching "forex lot size converter" or "what is a micro lot in forex" are usually running into the same confusion: brokers advertise minimum trade sizes in different unit types, and converting between them by hand is an easy place to make a costly mistake. This tool solves that instantly — enter an amount, choose whether it's in standard, mini, micro, or nano lots (or raw currency units), and every equivalent updates immediately, with no calculate button needed.
The four lot sizes are standardized across nearly every broker: a standard lot is 100,000 units of the base currency, a mini lot is 10,000, a micro lot is 1,000, and a nano lot — offered by a smaller number of brokers, mostly aimed at very small accounts or strategy testing — is 100 units. Searches for "standard mini micro lot calculator" spike heavily among traders opening their first account, since minimum trade sizes and account minimums are usually quoted in one of these four units, and matching your intended risk to the right lot size is a prerequisite for everything else you do as a trader.
This convert lots to units forex tool is intentionally minimal because the underlying math is simple multiplication and division — the value it adds is speed and the elimination of manual error, not complexity. That makes it a natural companion to the Position Size Calculator, which outputs a recommended position size in standard lots: if your broker's platform only accepts micro or nano lot increments, this converter instantly translates that recommendation into the units your broker actually uses.
Because lot size directly determines pip value (a pip on a full standard lot is worth roughly ten times what it's worth on a mini lot, and a hundred times a micro lot, for USD-quoted pairs), understanding lot conversions is also foundational to reading a pip value calculator correctly. If you're new to Forex and still building intuition for how position size, lot size, and pip value relate to each other, working through this converter alongside the Pip Calculator is one of the fastest ways to get comfortable with the unit conventions the entire market is built on.
This converter is also handy when comparing brokers before opening an account. Since minimum trade sizes and account funding requirements are often advertised in different lot units depending on the broker, being able to instantly translate a "0.01 lot minimum" into raw units — or the reverse — makes it much easier to compare offers apples-to-apples rather than getting tripped up by inconsistent terminology across platforms.
