What is the Lot Size Converter?

What Is a Lot Size Converter?

The Lot Size Converter instantly translates between different lot size formats used in forex trading: standard lots, mini lots, micro lots, nano lots, and raw units. Since different brokers, platforms, and regions use varying terminology, this tool ensures you always know exactly how much currency you're trading regardless of the format displayed.

Understanding lot sizes is fundamental to risk management. A "small" position of 0.1 lots might seem insignificant, but it actually represents $10,000 worth of currency (a mini lot). Misinterpreting lot sizes is one of the most common causes of unexpected losses among new traders.

Lot Size Reference Chart

  • 1 Standard Lot: 100,000 units of base currency — Pip value ~$10 (EUR/USD)
  • 1 Mini Lot (0.1): 10,000 units of base currency — Pip value ~$1
  • 1 Micro Lot (0.01): 1,000 units of base currency — Pip value ~$0.10
  • 1 Nano Lot (0.001): 100 units of base currency — Pip value ~$0.01

Why Lot Conversion Matters

  • Broker Differences: Some platforms display "units," others display "lots," some use decimals (0.01), others use thousands (1,000)
  • Risk Calculation: Accurate position sizing requires knowing exact unit exposure
  • Platform Migration: Moving between MT4, MT5, cTrader, and proprietary platforms often requires mental conversion
  • Cent Accounts: Some brokers offer "cent accounts" where 1 lot = 1,000 units instead of 100,000—causing massive confusion

How to Use This Calculator

How This Calculator Works

Step-by-Step Guide

  1. Select Input Format: Choose whether you're entering Standard Lots, Mini Lots, Micro Lots, or Units
  2. Enter Amount: Input your position size in the selected format
  3. View All Conversions: Instantly see the equivalent in all other formats
  4. Copy Values: Use the converted values for your trading platform or risk calculator

Real-World Example

Conversion Examples

Example 1: Converting Standard Lots to Units

  • Input: 1.5 Standard Lots

Conversion:

  • Standard Lots: 1.5
  • Mini Lots: 15
  • Micro Lots: 150
  • Units: 150,000

You are controlling 150,000 units of the base currency, worth approximately $150,000 for USD pairs.

Example 2: Platform Shows Units, Need Lots

Your broker displays position size in "units" and shows you have 25,000 units open.

  • Input: 25,000 Units

Conversion:

  • Standard Lots: 0.25
  • Mini Lots: 2.5
  • Micro Lots: 25

This is equivalent to a quarter of a standard lot, or 2.5 mini lots.

Example 3: Mixed Lot Sizes

You want to risk exactly $75 on a trade with a 30-pip stop loss. After calculating, you need 0.25 standard lots.

  • Your broker only allows mini and micro lots (not partial standard lots)
  • Solution: 0.25 Standard = 2 Mini + 5 Micro lots (0.20 + 0.05)

The converter helps you split positions when your broker has lot size restrictions.

When to Use

When to Use This Calculator

  • Switching Brokers: When moving between brokers that display lot sizes differently
  • Using Multiple Platforms: MT4 might show 0.01, while your broker's web platform shows 1,000 units
  • Risk Calculator Output: Position size calculators often output in lots—convert to units if your platform requires it
  • Cent Account Trading: Cent accounts use different lot sizes—always verify with the converter
  • Calculating Pip Value: Once you know units, you can accurately calculate pip value for any pair
  • Partial Position Sizing: Break down odd lot sizes into combinations your broker supports

Common Mistakes

Common Mistakes to Avoid

  • Confusing Lots Across Brokers: Some brokers define 1 lot as 100,000 units (standard), while "cent account" brokers define 1 lot as 1,000 units. Always verify your broker's contract specifications.
  • Decimal Confusion: Entering "0.1" when you meant "0.01" results in a position 10x larger than intended. A small decimal error can blow your risk management.
  • Ignoring CFD Lot Sizes: Indices, commodities, and crypto CFDs have different contract sizes than forex. Gold might be 100 oz per lot, not 100,000 units.
  • Not Checking Platform Settings: Some platforms allow changing the "default lot size" display. Ensure you know whether you're viewing standard lots or something else.
  • Mental Math Errors: Trying to calculate "0.37 lots in units" mentally leads to mistakes. Always use a converter for precision.
