How to visualize one part per million - Kim Preshoff + The TED-Ed Community

Translator: Nika Kotnik Reviewer: Matej Divjak

What does it mean to be one in a million?

Kaj pomeni biti eden na milijon?

Not in the greeting card sense,

Ne mislim napisa na voščilnici,

in the scientific sense,

mislim v znanstvenem smislu,

where one part per million is a unit of measurement.

kjer je en delec na milijon merska enota.

Parts per million counts the number of units of one substance

Delci na milijon merijo število enot ene snovi

per one million units of another.

na milijon enot druge.

It can measure concentrations when a small amount makes a big difference.

Lahko meri koncentracije, kjer majhna količina naredi veliko razliko.

For example, a concentration of just 35 ppm of carbon monoxide in the air

Na primer, koncentracija ogljikovega monoksida v zraku samo 35 ppm

is poisonous to us.

je za nas strupena.

We encounter measurements like this pretty often,

Take meritve srečamo precej pogosto,

but because it's hard to conceptualize really large numbers,

a ker si je težko predstavljati res velike številke,

it's difficult to wrap our brain around what one part per million really means.

težko razumemo, kaj en delec na milijon res pomeni.

So here are nine helpful ways to visualize it.

Tukaj je devet načinov, ki vam bodo pomagali pri vizualizaciji.

Če bi imel klavirske tipke 11.363-ih klavirjev,

If you had 11,363 pianos-worth of piano keys,

one of those keys would be about one part per million.

bi bila ena izmed teh tipk ena na milijon.

So would a single granule of sugar among 273 sugar cubes,

Tako kot eno samo zrno sladkorja v 273 kockah sladkorja,

one second in eleven and a half days,

ena sekunda v enajstih dneh in pol,

or four dots in the painting,

ali štiri pike v sliki

"A Sunday Afternoon on the Island of La Grande Jatte."

"Nedeljsko popoldne na otoku La Grande Jatte."

Your bath tub's capacity is about 60 gallons,

Kapaciteta vaše kopalne kadi je približno 227 litrov,

sedem kapljic črnila v njej bi bilo en del na milijon.

so seven drops of ink would be one part per million.

Angleška različica serije Harry Potter ima 1.084.170 besed,

The English version of the Harry Potter series has 1,084,170 words,

kar pomeni, da je beseda "hipogrif" na strani 221 v "Jetniku iz Azkabana"

which makes "hippogriff" on page 221 of "The Prisoner of Azkaban"

malo manj kot ena na milijon.

a little less than one part per million.

A million kernels of corn is about 1,250 ears,

Milijon zrn koruze je približno 1.250 storžev koruze,

so one kernel in that truckload would be one part per million.

tako da je eno zrno v tem kupu en del na milijon.

There are 10 million bricks in the Empire State Building,

V stavbi Empire State Building je 10 milijonov opek,

so one part per million would be a pile of just ten.

tako je en del na milijon kup samo desetih.

And finally, 100 people worked together to animate this video.

In na koncu, 100 ljudi je sodelovalo pri animaciji tega videa.

Collectively, they have about 10 million hairs on their heads.

Skupaj imajo na glavah približno 10 milijonov las.

Pluck ten of those hairs, and you have one in a million.

Izpuli deset teh las in imaš en del na milijon.
