Elo等级计算器
使用Elo等级系统，根据比赛结果计算球员或队伍等级的变化。
Elo等级计算器 gives you a faster way to work through practical calculation scenarios without rebuilding the same calculation from scratch every time. Start with A 球员的等级, B 球员的等级, 结果：A 球员的结果, and K因子（发展系数） and use the live outputs to estimate B 球员的预期得分, A 球员的预期得分, and B 球员的新等级 in one pass. This page is built to help you compare scenarios quickly, validate rough assumptions, and move into a related calculator when you need a second angle on the same problem.
Use The Calculator In A Few Steps
Work through the inputs deliberately, then compare outputs instead of relying on a single scenario.
Scenario Checks
Use these examples to verify the behavior of the calculator before you run your own values.
