Grade: F (Fail)
Percentage = (Part / Total) × 100. For example, if you scored 75 out of 100, percentage = (75/100) × 100 = 75%. Our calculator handles: percentage of a number, increase/decrease, difference between numbers, and grade calculations.
Percentage change = ((New Value - Old Value) / Old Value) × 100. If price increased from ₹100 to ₹120, change = ((120-100)/100) × 100 = 20% increase. For decrease, the result will be negative.
Conversion depends on university: For VTU, Percentage = CGPA × 9.5. For Anna University, Percentage = (CGPA - 0.75) × 10. For 4.0 GPA scale (US), Percentage = (GPA / 4) × 100. Use our CGPA calculator for accurate conversion.
Passing percentage varies: Most Indian universities require 40% (35% for each subject). CBSE/ICSE require 33%. Competitive exams like GATE have cutoffs around 25-30%. For placements, companies typically require 60%+ aggregate.
Grade to percentage (CBSE 10-point scale): A1 (91-100), A2 (81-90), B1 (71-80), B2 (61-70), C1 (51-60), C2 (41-50), D (33-40). Take the midpoint for estimation. Our calculator can convert grades to approximate percentages.
