by which 与in which 的用法
如果先行词是指时间的话，by which time 与in which 的用法区别如下：
(1) by which time 意思是“（到）那时”“（到）这时”，通常是指到某个时间点，即它的先行词通常应是时间点。如：
We arrived at noon, by which time the demonstration was over. 我们是中午到的，这时游行业已结束。
He came back eight months later, by which time the Japanese had decided to say yes. 八个月后他回来了，而当时日本人已经决定同意。
(2) in which 意思是“在此期间”，即它的先行词应该是时间段。如：
Galileo's ideas were well in advance of the age in which he lived. 伽利略的思想远远超越了他所生活的时代。
You have 14 days in which you can cancel the contract and get your money back. 你可在14天之内取消合同，收回钱款。

measured by是固定搭配，which引导定语从句，一般将by提前与which引导定语从句
by which在一般情况下与其他介词+which的用法是一样的，即与主语的谓语动词有关系，看谓语动词应该跟哪个介词。
