Your numbers
Change a trade size between of different sizes, or to units.
Type a number and pick what it is measured in.
This sets how many units are in one standard lot.
Mini, micro and nano lots are 0.1, 0.01 and 0.001 of a standard lot. Brokers differ in the sizes they accept, so check yours.
Your answer
0.35 standard lots is the same size as 3.5 mini lots, 35 micro lots, 350 nano lots and 35,000 units.

- 1 standard lot = 100,000 units. A mini lot is a tenth of that (10,000), a micro lot a hundredth (1,000) and a nano lot a thousandth (100).
- First turn what you typed into standard lots: 0.35 standard lots = 0.35 standard lots.
- Then multiply: mini = 0.35 ÷ 0.1 = 3.5; micro = 0.35 ÷ 0.01 = 35; nano = 0.35 ÷ 0.001 = 350; units = 0.35 × 100,000 = 35,000.

What is a lot in forex?
A lot is the standard size of a trade. In forex, one standard lot is 100,000 units of the base currency, so buying one lot of EUR/USD means buying 100,000 euros. Because that is large for many accounts, brokers also offer smaller lots, and the size you choose sets how much each pip is worth.
Lot sizes and what they are worth
| Lot type | In standard lots | Units (currency pairs) | Pip value, EUR/USD in a USD account |
|---|---|---|---|
| Standard lot | 1 | 100,000 | $10 |
| Mini lot | 0.1 | 10,000 | $1 |
| Micro lot | 0.01 | 1,000 | $0.10 |
| Nano lot | 0.001 | 100 | $0.01 |
How to convert
- Lots to units: multiply by the contract size, which is 100,000 for currency pairs.
- Units to lots: divide by the contract size.
- Mini lots to standard lots: divide by 10. Micro lots to standard lots: divide by 100. Nano lots to standard lots: divide by 1,000.
Worked examples
- 0.35 lots is 35,000 units, which is 3.5 mini lots or 35 micro lots.
- 25,000 units is 0.25 lots, which is 2.5 mini lots or 25 micro lots.
- 5 micro lots is 0.05 lots, or 5,000 units.
- For gold, one standard lot is usually 100 ounces, so 25 ounces is 0.25 lots. Choose gold in the converter to use that contract size.
Things to check with your broker
- The smallest size and the step between sizes. Many brokers allow 0.01 lot; some allow less, and some trade in single units.
- The contract size for metals, indices, oil and crypto, which is often not 100,000. Use the custom option to enter it.
- How your platform labels sizes. Some show lots, some show units, and a few use a different name for a mini lot.
Position size is only one part of a trade. To see what a size is worth per pip, use the pip value calculator, and to find the size that fits a chosen risk, use the position size calculator.
Frequently asked questions
+How many units are in a lot?
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 is 100. For gold, a standard lot is usually 100 ounces.
+What is the difference between a mini lot and a micro lot?
A mini lot is 0.10 of a standard lot, or 10,000 units, and a micro lot is 0.01 of a standard lot, or 1,000 units. A micro lot is ten times smaller than a mini lot.
+How do I convert units to lots?
Divide the number of units by 100,000 for a currency pair. So 25,000 units is 0.25 lots, which is 2.5 mini lots or 25 micro lots.
+How much is one pip worth for each lot size?
On a pair quoted in US dollars, such as EUR/USD, in a USD account, one pip is worth $10 for a standard lot, $1 for a mini lot and $0.10 for a micro lot. For other pairs it depends on the exchange rate; the pip value calculator on this site works it out.
+Why does the smallest lot size depend on my broker?
Brokers set their own minimum size and step. Many allow 0.01 lot (a micro lot) and some offer smaller sizes or trading in single units. The contract size can also differ for metals, indices and other instruments, so check your broker's specification.
