We encounter measurements every day, from the moment our alarm clock wakes us up and we adjust the water temperature for our shower, get dressed in clothes that fit, take doses of medicine, cook our meals & coffee, drive to work, buy gas & groceries, turn on a light switch, pay our bills, use gas/electricity, watch TV, build anything, pay for anything. How do we know these measurements are correct? What happens when these measurements happen in another country? How do we know the measurements “translate” from country to country & language to language? International System of Units and metrological traceability are the backbone of measurements. What does that mean? What are examples of non-traceable measurements? What happens when measurements go wrong? Proper measurements bring confidence & peace-of-mind to our lives. Understanding what measurements are help to ensure better measurements happen and life goes more smoothly.
