GPA Converter (100 ↔ 4.0 Scale)

Convert your grade out of 100 to the 4.0 scale using YÖK's general conversion table.

GPA Converter quickly handles a conversion or task that comes up often in everyday use. With GPA Converter, you get the answer instantly instead of calculating or looking it up by hand. Everything runs in your browser — your file or text is never uploaded to a server.

Step-by-step

Find the grade you want to convert on your transcript or diploma.
Enter it in the Grade out of 100 field. If your average has decimals, such as 78.45, enter it as is.
Click Run.
Note the 4.0-scale equivalent. If it's for an application, check which conversion table the institution expects.

Example

YÖK is Turkey's Council of Higher Education, and many Turkish universities grade out of 100. Say you graduated with an average of 82 and are now applying to a master's programme abroad that asks for a GPA on a 4.0 scale. Enter 82, run it, and you'll see the equivalent under YÖK's general table. When you put that figure on the form, mention that it was converted with the YÖK table, so the reviewer knows how it was calculated.

How does grade conversion work?

The tool converts a 0-100 grade to the 4.0 scale using YÖK's general conversion table: 90 and above gives 4.0; 85-89 gives 3.7; 80-84 gives 3.3; 75-79 gives 3.0; 70-74 gives 2.7; 65-69 gives 2.3; 60-64 gives 2.0; 55-59 gives 1.7; 50-54 gives 1.3; below 50 gives 0. Universities can differ slightly, so for official applications the institution's own table should be used.

Practical tips

Check the conversion rule of the university or institution you are applying to first.
Do not confuse a semester average with the overall average.
High-credit courses weigh more in an average, so you need to know the weights before converting.

Common mistakes

Using the tool's result in place of an official transcript.
Assuming 4.0 and 100-point scales are mapped the same way everywhere.
Treating small deviations caused by rounding as errors.

Things to keep in mind

Many universities have their own conversion table set by their senate. If your school has an official one, applications usually go by that.
Converting your overall average in one step can give a different answer than converting each course to a letter grade and re-averaging by credits.
Some institutions abroad recalculate your grades through their own credential evaluation service. In that case your conversion is for reference only.
For public sector jobs and official procedures, read which conversion the announcement asks for before using the result.

When is it useful?

It's useful when a master's, exchange programme or job application asks for a 4.0-scale GPA and you want a quick idea of what your grade out of 100 corresponds to. It gives you a reference point before you decide what to write on your CV.
