Scales & formulas

Grading scales, formulas & use cases

How each scale is calculated, who typically uses it, and where it shows up in practice.

4.0 Scale (US)

The standard US grading scale

User case

A student applying to US universities needs their transcript expressed on the familiar 4.0 scale for the application.

How it's calculated

CGPA = Σ(Grade Points × Credits) ÷ Σ(Credits)
A(4.0)+B+(3.3) at 3 credits each → 3.65

Who uses it

  • US college and university students
  • Study-abroad applicants

Applications

College applications, scholarship eligibility, transcript review.

5.0 Scale (India)

Common in Indian schools

User case

A student at an institution using O–F grading wants their overall CGPA on the 5.0 scale for a report card.

How it's calculated

CGPA = Σ(Grade Points × Credits) ÷ Σ(Credits)
O(5.0)+A(4.0) at 4 credits each → 4.5

Who uses it

  • Students at O–F grading institutions
  • School-level report cards

Applications

Report cards, internal school records, local scholarship criteria.

10.0 Scale (Global)

Common at Indian universities

User case

A university student enters direct 0–10 grade points per subject to track their CGPA each semester.

How it's calculated

CGPA = Σ(Grade Points × Credits) ÷ Σ(Credits)
8.5 and 9.0 at 3 credits each → 8.75

Who uses it

  • Students at VTU, JNTU, Mumbai University and similar
  • Engineering and postgraduate programs

Applications

Semester mark sheets, placement eligibility, higher-study applications.

Percentage Scale

Traditional 0–100% grading

User case

A school student wants their overall percentage across subjects for a job or admission form that asks for marks, not grade points.

How it's calculated

Percentage = Σ(Marks × Weightage) ÷ Σ(Weightage)
85% and 90% at equal weight → 87.5%

Who uses it

  • School students (CBSE, state boards)
  • Anyone filling forms that ask for marks

Applications

Job applications, admission forms, certificate verification.

Semester-wise CGPA

Cumulative across terms

User case

A student partway through a degree wants to know their cumulative CGPA across every semester completed so far, not just the current one.

How it's calculated

Enter every course from every semester together — the calculator weighs them all by credit hours in one pass.

Who uses it

  • Multi-semester degree students
  • Students tracking progress toward graduation

Applications

Degree progress tracking, honors and distinction eligibility checks.

CGPA to Percentage

Converting between scales

User case

A student with a 10-point CGPA needs a percentage figure for a form that only accepts marks out of 100.

How it's calculated

Percentage = CGPA × 9.5 (10-point scale)
CGPA 8.5 → 80.75%

Who uses it

  • Students filling job or visa application forms
  • Anyone reconciling scales for a form

Applications

Job applications, visa and immigration paperwork, credential evaluation.

Frequently asked questions

Quick answers about grading scales and using the calculator.

Understanding CGPA

How is CGPA calculated?

CGPA is calculated by summing the product of grade points and credit hours for each course, then dividing by the total credit hours: CGPA = Σ(Grade Point × Credits) ÷ Total Credits.

What's the difference between GPA and CGPA?

GPA usually refers to your average for a single semester. CGPA is the cumulative average across every semester combined, weighted by credit hours.

How do I convert CGPA to percentage?

On a 10-point scale, multiply your CGPA by 9.5 — a CGPA of 8.5 equals 80.75%. On a 4-point scale, divide by 4 and multiply by 100. This calculator does the conversion automatically.

Why might my CGPA differ from my official transcript?

Institutions sometimes apply their own rounding rules, retake policies, or scale-specific adjustments that this general-purpose calculator doesn't know about. Always treat the official transcript as the source of truth.

Using & Troubleshooting

What can I calculate with this tool?

Enter your courses, credit hours and grades on the 4.0, 5.0, 10.0 or percentage scale to get your CGPA, plus an automatic breakdown and conversions to the other three scales.

No. Every calculation runs locally in your browser — nothing you enter is sent to or saved on a server.

Why isn't my result showing?

Make sure at least one course has a valid credit-hour value greater than zero and a grade selected or entered, then click Calculate CGPA again.
