Most people use measurements and metrics every day.
They are so ingrained in our normal way of doing things that we often do not realize we are using them. When we drive our car, we watch the gauges, especially the gas, to make sure everything is all right. When we prepare for a vacation and a long drive, we may check the oil and tire pressure to make sure we are not going to have any problems. While following a recipe, we measure the ingredients and make sure the temperature of the oven is within the correct thresholds. Women expecting babies go to their doctor on a regular basis to monitor how things are progressing.
