Show the math
- 1 lot of EUR/USD = 100,000 units of EUR
1 lots - Units
1 lots × 100,000 = 100,000 units - Mini = 0.1 lot, micro = 0.01 lot, nano = 0.001 lot
1 lots = 10 mini = 100 micro
Quick answer
Lots = units ÷ contract size. In forex, 1 standard lot is 100,000 units of the base currency, a mini lot (0.10) 10,000, a micro lot (0.01) 1,000 and a nano lot (0.001) 100, so 25,000 units of EUR/USD is 0.25 lots. For gold at 100 oz per lot, 0.25 lots is 25 oz.

Lot sizes in units, ounces, contracts and coins
A lot is a fixed quantity of the underlying, and that quantity depends on the market. Read across a row to see what the same lot size buys in forex, metals, indices, oil and bitcoin.
| Lot type | Lots | Forex(units) | Gold(oz) | Silver(oz) | Indices(contracts) | Oil(barrels) | Bitcoin(coins) | EUR/USD pip(USD) |
|---|---|---|---|---|---|---|---|---|
| Standard | 1 | 100,000 | 100 | 5,000 | 1 | 1,000 | 1 | $10.00 |
| Mini | 0.1 | 10,000 | 10 | 500 | 0.1 | 100 | 0.1 | $1.00 |
| Micro | 0.01 | 1,000 | 1 | 50 | 0.01 | 10 | 0.01 | $0.100 |
| Nano | 0.001 | 100 | 0.1 | 5 | 0.001 | 1 | 0.001 | $0.010 |

Forex lots are standardised; metals, indices, oil and crypto contract sizes vary by broker (some use 10 oz gold lots or 0.1 index contracts), so check the contract size in your platform's symbol specification. Nano lots are offered only on some cent and micro accounts.
What is the Forex Lot Size Converter & Chart?
A lot is a standard quantity of the instrument you trade. The lot size converter turns any amount into standard, mini, micro and nano lots and into units, using the contract size of the instrument you pick.
Lots = Units ÷ Contract size
1 standard lot = 1.00, mini = 0.10, micro = 0.01, nano = 0.001
For forex, 1 standard lot is 100,000 units of the base currency, a mini lot 10,000, a micro lot 1,000 and a nano lot 100. Other markets use different contracts: gold is commonly 100 oz per lot, silver 5,000 oz, oil 1,000 barrels, index CFDs 1 contract and crypto 1 coin. Brokers vary for these, which is why the contract size can be changed.
Forex lot size chart
| Lot | Lots | Units (forex) | Pip value, EUR/USD | Gold (100 oz lot) |
|---|---|---|---|---|
| Standard | 1.00 | 100,000 | $10.00 | 100 oz |
| Mini | 0.10 | 10,000 | $1.00 | 10 oz |
| Micro | 0.01 | 1,000 | $0.10 | 1 oz |
| Nano | 0.001 | 100 | $0.01 | 0.1 oz |
What is 0.01 lot in dollars? On EUR/USD a 0.01 lot is 1,000 euros, worth about $1,100 at a 1.10 rate, and each pip moves it by $0.10. On gold a 0.01 lot is 1 oz, so a $1 move in the gold price is $1. The money you need to open it is that value divided by your leverage: about $37 at 1:30 for the EUR/USD example.
How to use this calculator
- Instrument — the contract size is set from it (100,000 units for forex, 100 oz for gold, and so on). Account currency is not needed for this calculator.
- Amount — the quantity you want to convert.
- Convert from — whether the amount is in Lots, Mini lots, Micro lots, or units (labelled Oz, Contracts, Barrels or Coins for non-forex instruments).
The result shows the same size in standard lots, mini lots, micro lots (with nano lots underneath) and units. If your broker's contract differs, change it under Contract specs. Show the math and Copy link with these numbers are below the result.
Worked example
Units to lots, EUR/USD. 25,000 units ÷ 100,000 = 0.25 lots = 2.5 mini lots = 25 micro lots.
Micro lots to lots. 35 micro lots × 0.01 = 0.35 lots = 35,000 units.
Gold. 0.25 lots × 100 oz = 25 oz. A broker with 10 oz per lot would need 2.5 lots for the same 25 oz.
When to use it
- Moving between platforms — some quote size in units, others in lots.
- Checking a position-size result — see what 0.37 lots means in units.
- Different contract sizes — compare the same exposure on brokers with different gold, index or oil specifications.
Common mistakes
- Assuming every instrument is 100,000 units per lot. Only forex is; check gold, indices, oil and crypto.
- Confusing "1 mini" with 1.0 lots. A mini lot is 0.10 lots.
- Forgetting minimum sizes. Many brokers accept 0.01 lots as the minimum; nano lots (0.001) are only available on some cent or micro accounts.
