I called my 13 yr old son with a favor the other day (home alone on spring break). Asked him to get a tape measure from my toolbox and measure the length of a fluorescent bulb so I could get a new one at lunch. I have several tape measures, one in English, on in metric and several in dual - he could have taken any of them. Without me prompting he read me the length as 300. I said is that millimeters he said yes.
Next I went to the store to find the bulb figuring id be looking for a 12" long bulb. To my surprise and delight I found what I needed on the shelf, only one choice. It was at Home Depot (do not remember the brand) and it was labeled as 30 cm with no English units. Al in all a very metrically illuminating experience for the day.
