分数转百分比计算器
Add multiple subjects with different maximum marks and get the overall percentage. More accurate than averaging subject percentages because it sums obtained and total marks before dividing.
计算示例
80/100 + 45/60: (125 ÷ 160) × 100 ≈ 78.13%

Why is this more accurate than averaging subject percentages?
Averaging percentages ignores that subjects have different weightings. Summing obtained and total marks before dividing gives the true overall percentage.
