Why GPA Scales Differ
The 4.0 scale is standard in the U.S. and Canada, but many international institutions use different point systems - 5.0, 7.0, and 10.0 scales are all common depending on the country and school.
How the Scales Compare
| Scale | Top Grade | Common In |
|---|---|---|
| 4.0 | 4.0 | United States, Canada |
| 5.0 | 5.0 | Some weighted U.S. high schools; parts of Europe |
| 7.0 | 7.0 | Some Latin American and international systems |
| 10.0 | 10.0 | India and several other countries |
Converting Between Scales
Because each scale simply stretches the same relative grade distribution, GPA values can be proportionally converted between them. For example, a 3.0 on a 4.0 scale is roughly equivalent to a 7.5 on a 10.0 scale (3.0 ÷ 4.0 × 10.0 = 7.5). Our calculators for the 5.0, 7.0, and 10.0 scales apply this same proportional method automatically.
Important: proportional conversion is a widely-used approximation, not an official standard - always confirm your specific institution's exact conversion policy for anything official, like a transfer application.
