How can I convert the old Microsoft word equations (version 3) to the new format?
Insert an equation with Equation Editor. On the Insert tab, in the Text group, click Object. In the Object dialog box, click the Create New tab. In the Object type box, click Microsoft Equation 3.0. If Equation Editor is not available, you may need to install it. Install Equation Editor. Exit all programs. This font will enable display of Math equations created using Microsoft Equation Editor 3.0. Microsoft Equation Editor 3.0 is no longer supported. Math Equations created using Microsoft Equation Editor 3.0 may not display due to absence of MT Extra font. To fix the issue download and install MT Extra font and restart the Office application. Micro patch rejuvenates abandoned Office add-on. This is mainly of concern to those dealing with equations in files created prior to Office 2007, which includes a separate equation writing component not implicated by the security issue. Microsoft retained Equation Editor 3.0 in later versions of Office to maintain backward compatibility. MathType-to-Equation in 3 steps. Save your document as Microsoft Equation - RTF GrindEQ using standard Save As menu: on the File tab, click Save As and then click Browse in the Save as type list, click Microsoft Equation - RTF GrindEQ (.rtf) and Save the document. Microsoft equation editor 3.0 free download - Microsoft XML Parser (MSXML) 3.0 Service Pack 7 (SP7), Free Equation Editor, Microsoft XML 3.0 Core Services Vulnerability Patch, and many more programs.
I have an old document file full of equations, and an automatic conversion solution rather than re-typing all equations will be a huge time-saver!
I also tried GrindEq,but word crahes after conversion!
Edit 1: I'm using Microsoft Office Pro Plus 2013 (64-bit) on Win 8.1
Edit 2: I also installed MathType. It supports lots of different formats to convert to, but I could not find Microsoft equation!

This is a bit lengthy, but it works!
- Download and LibreOffice. It's free. Only the Windows version works, the Mac (OS X) version won't work (I tried it).
- Go into Word and save your file as a .doc (if it's not already in that format)
- Go into LibreOffice, open the .doc file and save it as a .odt file
- Go into Word, open the .odt file and save it as a .docx
This reduced the file size of some of my Word files with lots of equations by 90%

When you open a document containing an equation that was written in an older version Word, you need to use Equation 3.0 or the add-in that was used to write the equation to change it. Equation 3.0 is available in Word 2013 and when you click in an equation written with Equation 3.0, it will open automatically.
Double-click the equation that you want to edit.

Make the changes that you want.
If you convert an older document to the current format, you can use Word 2013’s more powerful built-in tools to write an equation. However, any old equations written using Equation 3.0 or using an add-in must be manually recreated if you wish to use Word 2013’s built-in equation editor.
To convert a document, click File > Info > Convert.

Unless you try to convert a new document into an older one, you should see the compatibility options for your Microsoft Word.
Windows has many compatibility options. You can check their Help Site to see if your question is included in the Help center or in the Forums.
Offering more details would help us. Give us the solutions you tried.
You can install EQ 3.0 to edit equations in older word. Choose EQ 3.0 in object. If you want to make a full convert, you'll need to use a third party software.

Mathtype is a commercial program to convert equations in more than 500 formats.
It is well praised. I have seen many references to this program to deal with Word Compatibility Problems.
MathType has a free 30 day free trial you could use to convert your equations for free.

I use a trick that isn't a solution, but you can try a chance.
Log into One Drive with your Microsoft account, upload your file, and open it on Office Online, then save it or print as PDF.
