Question

why must a scientist use standard units of measure in experience and work

Answer 1

If a scientist says, "I measured a horse, and it was 20 hands tall," then other scientists will know the exact height of the horse if hands is a standard unit of measurement. However, if the term hands can mean a lot of different things depending upon whose hands are used, then other scientists will not know the height of the horse as accurately so that is your answer

Answer 2

Answer:

Standard units are commonly used units of measurement, which help us measure length, height, weight, temperature, mass and more. These units are standardized, which means that everyone gets the same understanding of the size, weight and other properties of objects and things.
