The National Measurement Institute (NMI) has released the final videos in the series explaining the 7 basic units of measurement simply for kids.

Australia’s Chief Metrologist and head of the NMI, Dr Bruce Warrington travels through time and space in the Tardis (which was kindly supplied by the ABC) to talk about each basic unit. In the videos, Bruce discusses how we measure each unit and how it has changed over time.

The final videos are on the candela which measures brightness, ampere which measures electricity, and mole which is the unit for measuring substance.
