Hubble length

[Golfer]

I am presently reading a paper on Inflation. It uses the term Hubble length. Can someone provide the Hubble length in cm.

The Hubble time is about 14 billion years. That means the Hubble length is about 14 billion lightyears. 13.8 might be better.

definitions: the hub time is 1/H0
the hub length is c/H0

just use google calculator. type this into the google search window verbatim
71 km/s/megaparsec
and press "search"

you will get an inverse time in Hertz

now type c divided by that, verbatim, in other words
c/(71 km/s/megaparsec)
and say search again

you will get 1.3 x 1026 meters

that is the hubble length in meters
google calculator will just calculate it for you automatically and tell you that

Can someone provide the Hubble length in cm.about 14 billion lightyears.
Thus, it is probably silly to describe it in centimeters.

Google calculator also does automatic unit conversion, you can say things like

c/(71 km/s/megaparsec) in centimeters

It is a great tool.
