Certain chemical reactions take place at certain temperatures. Try making beer or wine without measuring the temperature of the process, and you will get foul-tasting swill.

The above allows us to predict what will happen when the object being measured is used. For instance, we can find density from mass and volume, and that will allow us to predict what will happen when it is placed in water. We can find the mass of an object and use physics to predict what will happen when the object is going at a certain velocity towards another mass of another velocity. Temperature is a very important measurement because certain things occur at certain temperatures. All elements have melting/boiling/freezing points (the temperatures at which the element turns to liquid from solid, turns to gas from liquid, and turns to solid from liquid). And of course, when the temperature changes, so does the volume of the object (and thus changes the density, although that isn't one of your measurements in the question...) There are lots of other reasons, of course.

so that there is a basis for one to conduct experiments accurately and safely. otherwise we wouldn't be able to PROVE anything because there is nothing to measure it against.

stir it up and stick a thermometer in it.
