Ω Ohm Symbol Alt Code Shortcuts (Typing Omega on keyboard)

Meet the Ω (Omega) symbol: not just the last letter in the Greek alphabet, but a superstar in the world of science and math. It’s way more than just a symbol; it’s the key to talking about electricity. Omega stands for ohm, which is how we measure resistance in electrical stuff. Imagine it as a big deal in subjects like physics and engineering because it helps us understand how electricity flows. So, it’s not just the end of the alphabet—it’s where a lot of exciting science stories begin!

Whether you’re drafting a scientific paper, compiling data, or simply exploring the vast realms of science and technology, knowing how to input this essential symbol using your keyboard is a valuable skill.

This blog post aims to demystify the process, offering you various methods to type the Ω symbol using keyboard shortcuts and alt codes, regardless of your operating system or the type of keyboard you’re using.

Without any further ado, let’s get started.

Method #1: The Ohm Symbol Alt Code Shortcut

The Omega or Ohm Symbol Alt Code is 234. Using this shortcut, you can type this symbol (Ω) on any Windows keyboard or PC. To do this, press down the Alt key and type the Omega Alt Code (i.e. 234) using the numeric keypad, then release the Alt key.

How to use the Ohm Symbol Alt Code Shortcut

If the above quick guide didn’t make sense to you, obey the step-by-step instructions below to type the Omega symbol on a Windows Keyboard using this alt code shortcut:

  • Step 1: Place your insertion pointer where you need to type the Ω symbol.
  • Step 2: Press and hold the Alt key on your keyboard.
  • Step 3: While pressing down the Alt key, type the Ohm symbol’s alt code (234) using the numeric keypad.
  • Step 4: Release the Alt key after typing the Alt code.

Note that you must use the numeric keypad to type the alt code. You must also turn on your NumLock key to be able to use the numeric keypad. If you are using a Laptop that does not have the numeric keypad, you can press Fn+NmLk keys simultaneously to turn on the hidden numeric keypad for laptops with smaller keyboards. 

This is how you may use the Alt Code method to type the Ohm symbol anywhere on your Windows PC including Microsoft Word, Excel, One Note, Sticky Note, PowerPoint or even somewhere on your browsers like Google Docs or Word Online.

Method #2: Typing the Ohm Symbol on a Mac

For Mac users, typing the Ohm (Ω) symbol is a breeze, thanks to the operating system’s built-in shortcuts and features designed to make inserting special characters straightforward.

Whether you’re crafting a document, preparing a presentation, or working on a project that requires the frequent use of the Ω symbol, here’s how you can do it with ease.

Using the Character Viewer

The Character Viewer in macOS is a reliable tool for inserting various symbols, including the Ohm symbol.

Below are the steps:

  • Opening the Character Viewer: You can access the Character Viewer by clicking on the Edit menu in most applications and selecting Emoji & Symbols, or you can use the shortcut Control + Command + Spacebar. This opens a window showcasing a wide array of characters, from emoji to mathematical symbols.
  • Finding the Ohm Symbol: Once the Character Viewer is open, you can find the Ohm symbol by typing “Ohm” into the search bar at the top of the window. This will filter the results, showing you the Ω symbol.
  • Inserting the Symbol: Click on the Ω symbol to insert it into your document, presentation, or wherever you need it. You can also double-click the symbol to add it to your text.

Using the Keyboard Shortcut

Shortcut Key: The quickest way to type the Ω symbol on a Mac is by using a simple keyboard shortcut. Simply press Option + Z, and voilà, the Omega symbol will appear where your cursor is placed.

Ohm Symbol for Mac

This shortcut is an efficient way to insert the symbol without navigating through menus or remembering complex codes.

If using the Option + Z shortcut on a Mac doesn’t result in typing the Ohm (Ω) symbol, it’s possible that the keyboard layout or system settings might differ or have been updated. It’s worth checking your system preferences for keyboard shortcuts or consulting the macOS support documentation for up-to-date information.

Customizing Keyboard Shortcuts

For users who frequently need the Ohm symbol but cannot use the Option + Z shortcut, customizing a keyboard shortcut could be a more efficient solution.

  • Go to System Preferences > Keyboard > Text.
  • Click the + button to add a new text replacement.
  • In the “Replace” column, type a short sequence of characters you’ll remember (like “ohmsymbol”).
  • In the “With” column, paste the Ω symbol (you can copy it from here or from the Character Viewer).

This method allows you to type your custom shortcut in any text field, and it will automatically be replaced with the Ω symbol.

Whether you prefer the immediacy of keyboard shortcuts or the versatility of the Character Viewer, your Mac has you covered. With these tools at your fingertips, integrating the Ω symbol into your work is easier than ever, allowing you to focus on the content rather than how to type special characters.

Method #3: Typing the Ohm Symbol in Microsoft Word with 2126, Alt+X shortcut

One of the most efficient methods to insert this symbol is by using the Unicode character code followed by a simple keyboard shortcut.

Here’s how you can do it using the code 2126 and the Alt+X command.

Step-by-Step Instructions

  1. Place your cursor at the location in your Word document where you want the ohm symbol to appear.
  2. Type 2126 while your cursor is positioned where you want the symbol. This code is the Unicode reference for the Ohm (Ω) symbol. Remember, you won’t see the symbol just yet.
  3. After typing 2126, press Alt+X on your keyboard. This command tells Word to convert the code you’ve just typed into its corresponding Unicode character. As soon as you press Alt+X, the code 2126 should instantly transform into the Ω symbol.

Tips for Success

  • Immediate Conversion: Make sure to press Alt+X immediately after typing 2126, without adding any spaces. If you type anything else or move the cursor before pressing Alt+X, Word might not recognize the code correctly, and the conversion won’t happen.
  • If It Doesn’t Work: Occasionally, the Alt+X shortcut might not work, possibly due to specific settings in Word or your keyboard configuration. If this happens, you can try inserting the symbol using Word’s built-in Symbol menu (Insert > Symbol > More Symbols) and searching for the Ohm symbol there. Alternatively, check your Word or system settings to ensure keyboard shortcuts are enabled.

Using the Unicode 2126 followed by the Alt+X command in Microsoft Word is a quick and straightforward method to insert the Ohm symbol into your documents.


We’ve journeyed through various methods to type the Ω symbol, catering to users across different platforms, from Windows shortcuts and Mac’s Character Viewer to the precise Unicode technique in Microsoft Word.

Embracing the Ω symbol in your work not only enriches your documents but also connects you to the broader narrative of scientific discovery.

Thank you for diving into this guide. May your work be seamless, your knowledge deepens, and your documents shine with the clarity and precision that symbols like Ω bring to the table.

After a little research I found that Alt + 234 = Û where code page 850 is used (the default OEM code page for UK and some other English speaking countries) and Alt + 234 = Ω where code page 437 is used (the default OEM code page for US) so maybe you could update your header to read "Ohm Symbol Alt Code & Shortcut (Omega Ω on a US keyboard)". Hope that helps.

Thanks Les for shearing your findings. I really appreciate your input

Hi Abarika Abdulai, my PC is an i7-4790 CPU with a Gigabyte Technology motherboard running Microsoft Windows 7. Yes I would agree that the OS is rather old but I would not have thought that there would be any reason for the alt-codes to change with a later version OS. Note that if you go through the thread you will see that FRANCO P and TJUKKEN are getting the same result that I am getting. Maybe you need to rethink what you once assumed was an absolute. There must be a reason for the difference of course.

Of course there is definitely a reason for the difference and the reason is what I want to find now. To be specific, please which brand is your PC.

Windows OS. Microsoft Word. Numeric keypad on the right. I make sure NumLock is turned on. I will copy & paste what happens when I perform ALT + 234 as I don’t want you to think I am making this up… Alt + 234 = Û Please. It doesn’t work. Alt + 234 = Û

@Abarika Abdulai, Yes, in MS Word, but not anywhere else. If you’re typing an email eg, it doesn’t work. So forget Word here.

Hi Les, I'm not really sure why this isn't working on your end. However, you can also use Alt + 8486 in Microsoft Word.Thanks
