The phrase "to measure against" means to compare or evaluate something against a standard, criterion, or benchmark. It is used in various contexts such as business, science, and education. For example, when evaluating the performance of an employee, one may look at their achievements and compare them with the goals set for that position. Similarly, in scientific research, data collected from experiments are measured against predetermined hypotheses to determine if they support or reject it. In essence, "to measure against" is a way of determining how well something performs relative to an established standard.
