Just two years ago my car’s 50 kWh battery weighed around 350 kg, now you can get a 45 kWh battery that fits in the palm of your hand!

    The moon is roughly 385 megameters away, or 0.4 gigameters!

    Do we use MM for megameters and mm for millimeters? i think this might start to get confusing. We should probably clarify a few things before some tradie apprentice builds the galaxy’s largest bookshelf.

      Yes, millimeters, or any other milli measurement (EG milliamps) starts with a lower case.

      Kilo and up is capitalised.
