Have you ever stopped to wonder what ruler rules them all? How we set the standard for height, for weight, for everything around us? What if you weighed one thing one day, and travelled to another country and suddenly gained 5 kgs or had to use an entirely different weight system? What if you weighed one thing this week and more the next? This week we find out the history measurement systems, how we've standardised them and come up with unique and repeatable measures that don't rely on artefacts (real and metaphorically).
