1. Convert 70 CWA to GPA
A CWA (Cumulative Weighted Average) of 70 is typically considered a "B" grade in many grading systems. On a standard 4.0 GPA scale:
70 CWA can convert to a GPA of around 3.0 to 3.3, depending on the specific conversion formula of the institution.
For example, if using a direct percentage-to-GPA formula (CWA ÷ 25), 70 ÷ 25 = 2.8.
However, some institutions may round this up to 3.0 for simplicity.
2. Convert 63 CWA to GPA
A CWA of 63 generally translates to a "C" grade.
Using the direct formula (63 ÷ 25), this gives approximately 2.52 GPA.
Depending on the school’s specific scale, this could be rounded to 2.5 or 2.6 GPA.
3. What is 60 CWA to GPA?
A CWA of 60 is considered a lower "C" grade.
On the 4.0 scale, 60 ÷ 25 = 2.4 GPA.
Depending on their scale and rounding rules, some institutions may classify this as a 2.0 or 2.5 GPA.
4. Convert 66 CWA to GPA
With a CWA of 66, this is often viewed as a "C+" or "B-" grade.
Using the standard calculation (66 ÷ 25), you get a 2.64 GPA.
In some schools, this could be rounded to 2.7 GPA.

Offered by World Education Services (WES), this free online resource helps international students and professionals assess how their academic performance aligns with the 4.0 GPA scale commonly used in the United States and Canada.
How is CWA calculated?
To understand the CWA-GPA conversion better, it's essential to understand how both are calculated. Here are the steps involved in the CWA calculation.
- To start, one must have information about all the units they have been assessed for, the credit hours for the said units, and the marks scored in each unit.
- Multiply the score attained in each unit by its credit hours. So, if you attained 75 in unit A, which had three credit hours, your weighted marks for the unit would be 75*3, which is 225. Do this for all the units you have done so far.
- Add all the weighted marks. The sum is known as the cumulative weighted marks.
- Add all the credit hours you have attained so far. If, for example, you have done 11 units with two credit hours each, your cumulative credits are 11*2, which is 22.
- Divide the cumulative weighted marks by the cumulative credits to obtain the Cumulative Weighted Average. This means if your cumulative weighted marks are 1,500 and your cumulative credits are 20, your CWA is 1,500/20, which is 75.
Here is a look at the degree classifications under the CWA grading system
- First Class: 70.00 and above
- Second Class Upper: 60.00 – 69.99
- Second Class Lower: 50.00 – 59.99
- Pass: 40.00 – 49.99

How can I calculate my GPA? To calculate their grade point average, they must know the number of credits attempted (similar to credit hours in CWA), the final grades for each unit taken, and the point values for those grades. Under the Grade Point Average system, an A is 4.00 points, a B is 3.00 points, a C is 2.00 points, and a D is 1.00 points.
Here is how one can calculate their cumulative GPA.
- Multiply the credit attempts by the grade obtained. If, for example, you sat for a 3-credit exam in Introductory IT and attained an A, you would multiply 3 (the credits) by 4(the grade point) to obtain the weighted grade points.
- Repeat step one for all units covered so far.
- Add the weighted grade points to obtain the cumulative weighted grade points.
- Divide the cumulative weighted grade points by the cumulative credits to obtain the Grade Point Average.
How do you convert CWA to GPA?
How do you calculate GPA from marks? Here are the steps to converting CWA to GPA in Ghana
- Start by dividing your marks by 100 (essentially converting them into percentages). If, for example, you have a CWA of 83, divide it by 100 to obtain 0.83.
- Multiply the result by 4. This step is done since we are doing a conversion into a 4.0-point GPA.
- From the previous example, we would multiply 0.83 by 4 to obtain 3.32 (approximately 3.3).
- The figure obtained after the multiplication is the Grade Point Average. From our example, the student with 83 marks in CWA would have a GPA of 3.3.
However, it is important to note that the actual conversions are done by the institutions and may vary from those of the general formula given above.
How do I convert my Indian GPA to a 4.0 scale?
Most Indian universities use the 10-point GPA grading system. When students from these institutions move to other universities in Europe or America, their 10-point scores are converted into 4.0-point scores. Here is a table with the conversions.
10-point GPA | Equivalent 4-point GPA |
8.5-10 | 4.0 |
8.0 – 8.4 | 3.7 |
7.5 – 7.9 | 3.3 |
7.0 – 7.4 | 3.0 |
6.5 – 7.9 | 2.7 |
6.0 – 6.4 | 2.3 |
5.5 – 5.9 | 2.0 |
5.0 – 5.4 | 1.7 |
4.5 – 4.9 | 1.3 |
4.0 – 4.4 | 1.0 |
How to convert GPA to CWA
Those students coming from a GPA system to one that uses CWA need to have their CGPA converted into CWA. Here are the steps to do this conversion.
- Take your 4.0-point GPA and divide it by 4. If, for example, you have a 3.5 Grade Point Average, divide the 3.5 by 4 to obtain 0.875.
- Multiply the result by 100.
- From the above example, the student would have a CWA of 87.5, obtained by multiplying 0.875 by 100.
What are the different GPA models?
The two main Grade Point Average models are the weighted and unweighted systems. The unweighted GPA system does not consider the difficulties in each unit and thus has no credit hours. The weighted system considers each unit's difficulty, thereby giving more weight to more challenging ones.
What is a CWA of 70 in GPA?
A CWA (Cumulative Weighted Average) of 70 typically translates to a GPA of around 3.0 - 3.3 on a 4.0 scale, depending on the conversion formula used by the institution. Some schools may use a direct percentage-to-GPA scale, while others apply a more complex calculation.
What is 70% in GPA?
On a standard 4.0 GPA scale, 70% is typically a 2.7 or 3.0 GPA.
However, this can vary depending on the grading scale used by your institution.
How can I convert my marks to GPA?
Convert your total marks or percentage to a standard scale (typically 0-100%).
Use the GPA conversion formula of your institution (e.g., percentage ÷ 25 for a 4.0 scale).
Calculate the GPA for each course and find the weighted average if needed.
What is 70% of a 4.0 GPA?
70% of a 4.0 GPA is 2.8.
This is calculated as
0.7×4.0=2.8
How does KNUST calculate GPA?
The Kwame Nkrumah University of Science and Technology, commonly known as KNUST, does not use a GPA grading system. Instead, it uses a CWA system.
At Kwame Nkrumah University of Science and Technology (KNUST), the primary grading system is based on the Cumulative Weighted Average (CWA), which reflects the average performance of a student across all courses, weighted by their respective credit hours. However, when students need to transition to systems that use GPA, understanding the KNUST CWA to GPA conversion becomes essential.
Figuring out how to convert CWA to GPA is essential for students looking to move from schools that use the CWA system to those that use GPA. Conversion is easy to do when one has all the necessary information and figures.
