I still root for metric prefixes over language-based numbers
(kilogram over one thousand grams, even megameter over
one thousand kilometers).
But it’s still hard to imagine some
Meter
1 nanometer, a few atoms wide
1 micrometer, thinner than hair, or paper
1 millimeter, as thin as thin pasta
1 meter, within arm’s reach
1 kilometer, a short jog
1 megameter, as wide as Montana
1 gigameter, as far as to the Moon & back
1 terameter, as far as to Jupiter
1 petameter, to the other side of the Milky Way
Gram
1 nanogram, 50 trillion carbon atoms
1 microgram
1 milligram
1 gram, a small noodle
1 kilogram, a pizza
1 megagram, a small sports car
1 gigagram, 3-4 Airbus A380s (or 2 ISSs)
1 teragram, 2 of the largest supertankers
1 petagram, maybe 5% of Lake Michigan
Second
1 nanosecond, a few CPU cycles
1 microsecond, a context switch
1 second, one 1000, two 1000…
1 kilosecond, 16 minutes
1 megasecond, 12 days
1 gigasecond, 32 years
1 terasecond, uh.. 32,000 years
1 petasecond, …… 32 million years
