The world doesn't grade on one scale. Neither do we.
105 calculators, one per country's real system - inverted scales, negative grades, and the local numbers (GWA, CGPA, moyenne, jämförelsetal) computed the way each registrar computes them, privately in your browser.
What is GradeKiln?
GradeKiln is a set of free grade calculators - 105 of them, one per country's real grading system, from the US 4.0 GPA to Chile's 1.0-7.0 escala and Denmark's 7-trin scale. Each one runs the credit-weighted arithmetic registrars actually use, entirely in your browser.
What makes GradeKiln different from other GPA calculators?
Three things. First, every country gets its real system, not a re-skinned 4.0: the scales where a lower number is better (Germany, Switzerland's opposite twin, the Philippines), Denmark's negative −3 grade, Italy's 30 e lode, Argentina's promoción at 7, Peru's tercio superior. Second, every calculation runs in your browser - grades are never uploaded, and pages work offline. Third, every page prints the exact grade table it uses, so you can verify the arithmetic against your own handbook.
Why does a generic GPA calculator give a different answer on a foreign transcript?
Because grading systems disagree about direction and shape, not just numbers. In Germany 1.0 is the best grade and 4.0 barely passes; across the border in Switzerland 6 is the best and 4.0 also passes; in the Philippines 1.00 is the top grade. Denmark's −3 actively subtracts from an average. A calculator built for the US 4.0 silently mangles all of these - GradeKiln implements each system's own arithmetic instead.
Which country-specific numbers can GradeKiln calculate?
The local metric each country actually asks about, by its local name: CGPA in India and Nigeria, GWA in the Philippines, WAM context for Australia, jämförelsetal and meritvärde in Sweden, the Notenschnitt in Germany and Switzerland, moyenne and mentions in France, média/CR in Brazil, promedio ponderado and tercio superior in Peru, UK degree classification from module marks, and more - with the honours or classification band computed live where the country uses one.
Does GradeKiln work without an account, and does it work offline?
Both. There is no sign-up, no email, and no limit - and because each page's calculator is plain JavaScript running locally, the page keeps working with the network disconnected once it has loaded. Your rows are saved in your own browser so they survive a refresh.
Is GradeKiln free?
Yes. Every calculator is free, with no signup, no account, and no limits. The site is supported by ads.
Does GradeKiln upload or store my grades?
No. The math runs as plain JavaScript in your browser. Courses and grades are saved only in your own browser's local storage so they survive a refresh; nothing is transmitted, and the pages keep working offline.
Which grading scales does GradeKiln support?
105 calculators grouped by region: North America (US college and high school, Canada's 4.33), Latin America (Mexico /10, Brazil's média/CR, Argentina 1-10, Chile's 1.0-7.0, Colombia /5, Peru's vigesimal /20), Europe (UK honours and UMS uniform marks, France /20, Germany 1.0-5.0, Switzerland's 1-6, Spain /10, the Netherlands 1-10, Italy's trentesimi, Denmark's 7-trin, Norway A-F, Sweden's jämförelsetal, Russia's 5-point scale, Poland's 2-5, Estonia's A-F, the 10-point scales of Latvia and Lithuania, Hungary's 1-5, Ukraine's 100-point scale), the Middle East (Saudi Arabia's 5.0 where an A is 4.75, Turkey's AA/BA letters into the AGNO), Asia (China's /100 average, Japan's 秀優良可, Korea's 4.5, Hong Kong's 4.3, Singapore's 5.0, Malaysia, Indonesia's IPK, Bangladesh's UGC scale, Vietnam's thang điểm 10, India's CGPA, Pakistan's HEC 4.0, Sri Lanka and SLIIT, the Philippine GWA, Kazakhstan's 4.0), Australia's 7-point, and Africa (Nigeria's 5-point NUC, South Africa's /100 with distinction at 75, Ghana's 4.0 with First at 3.60, Kenya's honours classes, Egypt's taqdeer percentages, Uganda's Makerere 5.0). Some pages are for one institution, where its arithmetic genuinely differs: Moratuwa's 4.2 A+, MIT's 5.0 scale, Cornell's 4.3, VTU's percentage formula, Anna University's no-arrears Distinction rule, and the four Hong Kong universities HKU, HKUST, CityU and CUHK. Each page shows the exact table it uses, including the scales where a lower number is better.
Where do the grading scales come from?
We take them. We do not work them out ourselves. Each scale comes from the body that sets it, which means a ministry of education, a national qualifications authority, or a university's own academic regulations. 64 of the 80 scales on this site come straight from that body, and every one of those pages names the document, links to it, and gives the date we last read it. 6 come from a document that reports the scale rather than setting it. Ten we had to assemble ourselves, because no authority publishes the scale anywhere we can reach. Those 16 pages say which they are, in plain words, right where you read the number, and explain how we arrived at it. The sources page lists every scale with its link and the date it gets read again.
How accurate are GradeKiln's calculators?
Each page implements the published scale it names and shows you the exact grade-point table it uses. Faculties set their own boundary and repeat-policy rules, so your institution's current handbook is always the final authority; if you spot a scale that is wrong or out of date, tell us and it gets fixed. We hold other sites to the same standard: the corrections page shows where published grade tables differ from the issuing body, with both versions and the sources.
Is GradeKiln affiliated with any university?
No. GradeKiln is independent and not affiliated with any university or institute. It is a sibling of FileKiln, in-browser file converters built on the same local-only principle.
