Equation conversion process from MathType 7 to MathType Add-in for Microsoft 365

If you are working in a Word document in Microsoft 365 and want to edit an equation created with MathType 7, you can do so using the MathType Add-in for Microsoft 365.

Convert from MT7 

You'll find the “Convert from MT7” tool in the MathType Add-in Ribbon tab:

This option scans the document for equations created with MathType 7 and prompts you to convert them to the Add-in's format. 

Please note that converted equations can't be edited by MathType 7 anymore. We recommend you to backup your document before converting the equations. 

To convert the equations, select the desired font and size, then click on Convert.

You'll get a confirmation once the conversion process has finished:

 

Conversion limitations

The converstion feature is only available in Word desktop app, not in Word online or Word for iPadOS/iOS.

 

In any conversion, some information may be lost:

• The appearance of equations may change after conversion; therefore, we recommend making a copy of the document before proceeding.
• This is a one-way conversion. Once you edit an old MathType 7 equation with the Add-in, it cannot be edited again with MathType 7; in the same way, you cannot edit with MathType 7 equations created with the Add-in.
• If the converted equations are not what you expected, you can undo the conversion (Ctrl+Z for Windows, ⌘+Z for macOS).
• Some format and style features are lost: “Only math” is translated. See the list below for more details.

Conversion result

Conversion examples

For instance, in the examples below, we show how the conversion could affect the style of your equations. Specifically, in the first example, we convert an equation written in MathType 7 with Times New Roman, size 12, to Classic, size 16. In the second example, both formulas are in Times New Roman size 16.

MathType 7 (Times New Roman, size 12) vs Add-in (Classic, size 16 [default])

MathType 7 vs Add-in (both Times New Roman 16)

What is kept in the conversion

• Symbols, and formula layout.
• Slant normal for functions.
• Slant normal and bold for vectors and matrices.
• Default slant italic for variables.
• Default slant normal for text.
• Greek letters.
• Fraktur and Doublestruck letters.
• Alignment:
  • Horizontal alignment for multiline: align left, centre, right, decimal and relational symbols.
  • Column alignment for matrices and tables: align left, centre, right, decimal and relational symbols.

What is lost in the conversion

When converting a MathType 7 equation, some custom format and style features may be lost. Notice that they can be tweaked again with the Add-in in most cases. The contextual tab will be your ally in doing these customizations.

• Font and size: equations will be converted to the default font and size in the Add-in.
• Colour: notice that once the equation is converted, you can modify the colour of its elements from the Add-in again.
• Nudges: Once the equations are converted, you can nudge the elements from the Add-in again if you want.
• Custom spacing: Custom spacing in multiline, matrices, scripts, big operators, fractions, radicals or embellishments.
• Custom style: MathType Add-in doesn’t allow defining custom styles for vectors, matrices, functions or other elements. Only default slant and weight for vectors, matrices, text, functions and variables will be kept.
• Alignment:
  • Custom vertical alignment for multiline: when converted, every multiline will align at the centre. Notice that you can modify the alignment again from the contextual tab.
  • Custom fence alignment: When converted, any fence alignment becomes baseline alignment. Notice that you can modify fence alignment again from the contextual tab.
  • Custom table and matrices row alignment: when converted, rows will align at the centre. Notice that you can modify alignment again from the contextual tab.
• Matrix separators: Notice that you can add matrix separators again from the contextual tab.
