得点からパーセントへの計算機

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.

  2. The calculator sums all obtained and all total marks.
  3. Read the overall percentage.

計算式

  • Comparing performance across subjects with different maximums.

よくある質問

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.
