In the states, it’s easier to imagine someone’s height online or how long something is with feet, so like if someone says they are 5”7, (170 cm) you can just picture 6 of a medium sized measurement and then get rid of about half. I understand you could picture 170 tiny things or 1 and a half big things as a meter’s equivalent, but is there a commonly used middle point between the two? I apologize if this is a stupid question.
