multiple choice question
if you use a celsius thermometer for one part of an experiment and a fahrenheit thermometer for another, what must you do before you graph these data together?
q you must convert your temperature readings to the same unit of measurement.
q you cannot graph them together. you must make two separate line graphs, then compare them.

You must convert your temperature readings to the same unit of measurement.
