Why do scientists use a standard measurement system?

Answer 1

Everyone uses a standard system, not just scientists. How would we ever do business with each other if each of us were free to define our own measurements? Most of the world uses the metric system of weights and measures while only the US have their own standards, but it is some math to determine the equivalent of gallons in liters or kilograms in pounds.

Answer 2

Standard measurements make it easier for everyone to know what that measurement means. The metric system, which is the standard system used by scientists, is specifically designed to be easy to use. The English system is much more complicated, mathematically.

Answer 3

So that they can tell other scientists about their work, and the other scientists will

understand what they're talking about and possibly pick up where the first scientist

left off.

Answer 4

To avoid ALL MISTAKES. By using a standard system they know what unit to use in formulas and if all scientists use the same units, you don't get blunders like a rocket crashing because one of the builders used the wrong units.
