Byte of data: a grain of rice
Kilobyte: a cup of rice
Megabyte: 8 bags of rice
Gigabyte: 3 container lorries
Terabyte: 2 container ships
Petabyte: covers Manhattan
Exabyte: covers the UK (3 times)
Zettabyte: fills the Pacific Ocean

@lproven Sorry but I did some math on the byte to kilobyte comparison. 1000 grains of rice is nowhere near enough for a cup. I’m assuming we aren’t talking cooked rice (but even then…). Perhaps if instead a bit is a grain of rice then a kilobyte could be a cup of rice.

@IanStuart @lproven Given the other Britishisms, I suspect the original presenter isn't using "cup" as a well-defined unit of volumetric measure, but just as in "a small cup you might have in a kitchen".

But even so, that's a tiny cup.

Is this measurement of data to grains of rice accurate?

This image purports that you can measure data in grains of rice - one byte being one grain of rice and one gigabyte then being three container lorries. Byte of data : one grain of rice Kilobyt...

@JdeBP @lproven @romaindurand @bytebro There's no possible way that something can be not precisely accurate but still be a useful analogy for relative sizes
