GPA Scale Converter

GPA Scale Converter: Convert a GPA between common 4.0, 4.3, 5.0, 7.0, and 10.0 scales using a proportional conversion, or enter a custom source and target scale.

How the GPA Scale Converter works

The GPA Scale Converter preserves the same proportional position on the source and target scales. A 3.50 on a 4.0 scale represents 87.5% of the maximum, so the proportional equivalent on a 4.3 scale is 3.76.

GPA conversion formula

Converted GPA = GPA value ÷ source maximum × target maximum. The percentage position equals GPA value ÷ source maximum × 100.

Worked example

To convert 8.2 on a 10.0 scale to a 4.0 scale, divide 8.2 by 10 and multiply by 4. The proportional result is 3.28 on a 4.0 scale.

When proportional conversion is appropriate

A proportional conversion is useful for rough comparisons, personal planning, and applications that explicitly request a linear scale conversion. It does not reproduce grade distributions, passing thresholds, course rigor, plus/minus rules, or institutional equivalency tables.

Universities and credential evaluators may require original grades or use their own conversion procedures. If an application provides a table or formula, follow that instruction instead of a general proportional result.

How to use the converter

Enter the GPA value, choose the original scale and target scale, and select Convert GPA. Choose Custom scale when your institution uses another maximum. The value must remain between zero and the selected source maximum.

Understanding international GPA scales

A higher scale maximum does not automatically mean easier grading. A 7-point or 10-point system may use different pass marks and grade bands. Keep the original GPA and source scale beside any converted estimate so readers understand its context.

For general information about U.S. institutions, visit the U.S. Department of Education College Scorecard. Official admissions decisions should rely on the receiving institution’s policy.

Choosing the right GPA scale

The GPA Scale Converter should always begin with the maximum shown by the original institution. Do not assume every transcript uses a 4.0 scale. Review the transcript legend, academic catalog, or admissions instructions before converting. If a school reports both weighted and unweighted GPAs, convert only the version requested by the recipient.

Rounding can also change the displayed result. This calculator keeps the full value during calculation and rounds only the final answer to the number of decimals you choose. For formal applications, retain the original GPA beside the converted estimate.

Frequently asked questions

Is a proportional conversion official?

No. It is an estimate unless the receiving organization explicitly accepts the proportional formula.

Can I convert a weighted GPA?

Yes for a mathematical estimate, but choose the correct weighted maximum and disclose that the original GPA was weighted.

Why is 3.5 on a 4.0 scale not always equal to 3.76 on a 4.3 scale?

Some institutions use grade-category mappings rather than a linear conversion, so official equivalents may differ.

Can I use a custom scale?

Yes. Choose Custom scale and enter positive source and target maximum values.
