Unreal Engine Unit Converter

Unreal Engine Unit Converter

Convert between Unreal Engine Units and real-world measurements easily. This tool helps you convert units like millimeters, centimeters, meters, inches, feet, and Unreal Engine Units for seamless game development and accurate scaling.

How the Conversion Works

Unreal Engine uses centimeters as its default unit, where 1 Unreal Unit (UU) equals 1 centimeter (cm). This converter helps you translate between Unreal Units and real-world measurements:

  • 1 millimeter = 0.1 centimeters = 0.1 UUs
  • 1 meter = 100 centimeters = 100 UUs
  • 1 foot = 30.48 centimeters ≈ 30.48 UUs
  • 1 inch = 2.54 centimeters = 2.54 UUs

Use this tool to ensure accurate scaling when importing or exporting models and assets in Unreal Engine.

As the creator of our new Unreal Engine Unit Converter, I’m delighted to elaborate on how it can enhance your workflow and ensure consistency in any game development or 3D project. Unreal Engine adopts centimeters (often referred to as Unreal Units, or UU) by default, and that can sometimes cause confusion when you’re modeling assets in meters, inches, or feet elsewhere. This converter eliminates that guesswork by providing fast, precise transformations between measurement systems—no more manual math or clumsy spreadsheets.

Comprehensive Features

  • Multiple Input Units: The tool supports meters (m), centimeters (cm), feet (ft), inches (in), and Unreal Units (UU). This breadth of options covers the most common scales used in 3D modeling and architectural workflows.
  • Direct Output: Once you’ve entered your value and selected both the origin and target units, the converter displays the result instantly, reducing trial-and-error.
  • Built-In Error Handling: If a user types a non-numeric character or leaves a field empty, the tool politely displays an error message, prompting for a valid input.
  • Intuitive Interface: The user-friendly layout presents input fields, dropdown menus for unit selection, and a concise “Convert” button. Even team members unfamiliar with conversion nuances can easily operate it.

Practical Applications

  1. Asset Creation: If you’re making a chair in a 3D software package that uses meters, you might model the seat height at 0.45 meters. When you bring it into Unreal Engine, you want that to translate to 45 Unreal Units. By using the converter, you verify the correct measurement instantly.
  2. Environment Prototyping: Designing a corridor or hallway in architectural software? Suppose it’s 3 meters wide. By converting 3 meters to Unreal Units, you get 300 UU, ensuring the gameplay space matches what you designed.
  3. Character Scaling: A character that stands 6 feet tall measures approximately 183 centimeters. With just a couple of clicks, you’ll discover it equates to 183 Unreal Units in engine, preserving the intended sense of realism.

Step-by-Step Example

Let’s say you have a door frame modeled to be 2.2 meters high and 0.9 meters wide in a third-party modeling tool. Here’s how you’d convert it to match Unreal Engine units:

  1. Enter 2.2 in the numeric field and select “meters” as the source unit.
  2. Choose “Unreal Units (cm)” as the target unit for the height.
  3. Press “Convert” to see that 2.2 meters equals 220 centimeters (UU) in Unreal Engine.
  4. Repeat for the width: 0.9 meters becomes 90 centimeters (UU).

Why It Matters

 

Maintaining correct proportions is essential for ensuring objects and characters move naturally and collide accurately within your scenes. A minor error in height or width can affect everything from animations and camera perspectives to player navigation. By centralizing all conversion needs into one tool, developers and artists can stay focused on creative tasks without worrying about unit mismatch or calculation errors.
