How This Tool Works

This tool has two parts. The first converts a grade from one country's or institution's system into another (percentage, CGPA, GPA, WAM, UK classification, and more). The second converts credit hours into ECTS, the credit system used across Europe. Both use standard, publicly documented conversion methods — not made-up numbers — but both are still estimates. Neither replaces an official credential evaluation from a body like WES, NARIC, or your target university's admissions office. If you're preparing applications right now, our CV and cover letter guide for agriculture jobs walks through how to present these credentials effectively.

What You Can Convert With This Tool

This free GPA calculator, CGPA converter, and grade conversion tool works as an all-in-one calculator for students comparing academic results and credit hours across different countries and university systems. Here's every conversion it supports:

• Percentage to GPA and GPA to Percentage — convert marks obtained into a 4.0 GPA scale, or the reverse.
• Percentage to CGPA and CGPA to Percentage — convert your marks into a CGPA out of 10 (or any scale you choose), and back again.
• CGPA to GPA and GPA to CGPA — convert between a CGPA out of 10 and a GPA out of 4.0, 4.3, or 4.5.
• GPA to WAM and WAM to GPA — convert a Weighted Average Mark (used by Australian universities) into GPA, or GPA into WAM. If you're targeting Australian programs, see our guide to funded agriculture PhDs in Australia.
• Letter Grade to GPA converter — convert a letter grade (A, A-, B+, B, and so on) directly into its GPA point value.
• UK Classification to GPA — convert a UK degree classification (First, 2:1, 2:2, Third) into an estimated GPA or percentage. See UK qualification levels explained for official context.
• 7-point GPA scale converter — convert to and from the 7-point GPA scale used by Australian and New Zealand universities.
• German grade calculator — convert a percentage into the German 1.0–5.0 grading scale, or a German grade back into a percentage, using the official Modified Bavarian Formula. See anabin for Germany's official foreign qualification database.
• EU/Nordic 10-point scale converter — convert a percentage or GPA into the 10-point scale used in the Netherlands, Denmark, and other Nordic countries.
• Credit hours to ECTS converter — convert your university's credit hours into ECTS credits for European university applications, credit transfer, or study abroad programs.
• Semester GPA calculator and cumulative CGPA calculator — calculate your GPA from individual course grades, marks, or credit hours, and combine it with your existing CGPA.

Part 1: Grade Conversion — How the Numbers Are Calculated

Every grade conversion in this tool works in two steps, no matter which system you start from.

1 Convert your grade into a percentage first

Percentage is the one common unit every grading system can be translated into, so the tool always converts to percentage internally before doing anything else.

• If you already have a percentage, no conversion is needed.
• If you have a CGPA or GPA, the formula is:

If you have a UK Classification (First, 2:1, 2:2, Third) or a Letter Grade (A, B+, etc.), these are bands, not exact numbers, so the tool uses the commonly accepted midpoint of that band as a working percentage (for example, a UK 2:1 is treated as roughly 64.5%, since a 2:1 covers 60–69%).

2 Convert that percentage into your target system, using country-specific grading bands

This is the part most conversion tools get wrong: the same percentage does not mean the same thing in every country. A strict grading country (where 85% is considered an excellent, top-tier result) needs a different conversion table than a country where percentages are graded on a gentler curve.

The German Grade Scale — Its Own Formula

Germany's 1.0–5.0 scale (where 1.0 is the best grade and 5.0 is a fail) doesn't use a country-band lookup like the others — it uses a direct mathematical formula, because German universities themselves define grades this way. This is called the Modified Bavarian Formula, and it's the real method used to convert an exam or coursework percentage into a German grade:

Any percentage below 50% is treated as a flat 5.0 (fail), because German transcripts don't further distinguish how someone failed — once you're below the passing line, the specific percentage no longer changes the recorded grade.

The same formula also works in reverse, to turn a known German grade back into an estimated percentage:

Course-Based GPA Calculator — How Your Semester GPA Is Worked Out

If you're entering individual courses rather than converting a single known grade, the tool calculates a credit-weighted average:

You can enter each course's result three different ways, and the tool converts each into grade points automatically before averaging them together:

• Letter grade — uses the standard US-style point scale (A = 4.0, A- = 3.7, B+ = 3.3, B = 3.0, and so on down to F = 0.0). This follows the common AACRAO grading conventions used by US institutions.
• Marks obtained (%) — the percentage is run through the same percentage-to-GPA conversion described above.
• Grade points earned — if you already know the exact quality points a course gave you, you can enter that number directly, with no further conversion.

For combining a new semester with your existing CGPA, the tool uses:

This works by converting both your old CGPA and your new semester GPA into a common 0–1 fraction of their respective maximums, combining them as a credit-weighted average, and then scaling the result back up to whichever maximum you want your cumulative CGPA expressed in (commonly out of 10 or out of 4).

Part 2: Credit Hours to ECTS — How the Conversion Works

ECTS (the European Credit Transfer and Accumulation System) is built around one fixed rule that never changes: one full-time academic year always equals 60 ECTS credits, no matter the country or subject. This tool uses that fixed rule as an anchor point, combined with your own program's real numbers, using the same duration-proportional method that many European admissions offices use for exactly this kind of conversion:

Two things are worth understanding about this formula:

• The factor is calculated fresh from your own program, not applied as one fixed number for every visitor. A 4-year, 240-credit-hour program produces a factor of exactly 1 (because 240 already equals 60 × 4). A 4-year, 130-credit-hour program — closer to how many Pakistani university programs are structured — produces a factor of about 1.85, which matches the "quick conversion formula" some Pakistani universities themselves publish for their students. The Higher Education Commission (HEC) of Pakistan publishes credit hour definitions and program frameworks that align with this approach.
• "Credit hours you actually completed" is your own real, exact number — it does not assume you finished with precisely the total your program requires. If your program requires 240 credit hours but you actually completed 243 (for example, from taking an extra elective), the tool reflects that real number rather than rounding you to a fixed total.

Why These Are Estimates, Not Official Conversions

Every number this tool produces is a published, standard approximation — the same kind of method real evaluators use as a starting point — but two important limits apply:

• Individual universities sometimes publish their own fixed conversion ratio (for example, some state directly that "2 ECTS = 1 credit hour" for their specific program). Where your target institution has published its own number, that number takes priority over this tool's estimate.
• For anything that actually matters — a real admissions decision, a credit transfer, or a visa application — the only source that counts is an official credential evaluation service (such as WES, ENIC-NARIC, or your target country's national recognition body) or the receiving university's own international office.
